A rock's long life 15

  • A boulder sits on a mountain for ten thousand years of weathering. Write its life in five short diary entries, a long time apart. Fact: weathering breaks rock down where it sits, with little or no movement.
  • A desert rock is being worn by salt, not rain. Write its puzzlement at what is happening in its cracks. Fact: salty water seeps into cracks and dries, and the salt crystals left behind break the rock.
  • A limestone statue has stood in the rain for three hundred years. Write what its face remembers looking like. Fact: rainwater takes up carbon dioxide and becomes a weak acid that dissolves limestone.
  • A rock explains the difference between weathering and erosion to a pebble that keeps mixing them up. Fact: weathering happens in place; erosion is the carrying away by water, ice, wind or gravity.
  • A tree root finds a crack in a rock. Write their hundred-year arm wrestle. Fact: in weathering, plant roots sometimes enter cracks in rocks and pry them apart.
  • An old stone step near you has been worn into a dip. Write who and what wore it down. Angle: weather did some of it; ten thousand shoes did the rest.
  • Sheets of rock peel off a great bare dome like the layers of an onion. Write the dome's opinion of losing a layer. Fact: in weathering, sheets of rock breaking away from exposed rock is called exfoliation.
  • Two rocks sit side by side on a hill; one is crumbling and one is not. Write the talk they have about weathering. Angle: one sits in the shade where the ice lasts; one sits in the sun.
  • Water seeps into a crack in a rock and freezes every winter. Write the slow widening as the rock feels it. Fact: frost weathering is the most important form of physical weathering.
  • Write a race between a mountain being worn down and a snail crossing a road. Decide who the crowd cheers for. Fact: once mountain building stops, weathering and erosion slowly level the mountain.
  • Write a rock's complaint about the lichen that has moved onto it without asking. Fact: lichens have been seen prying mineral grains loose from bare rock, a kind of weathering.
  • Write a rock's long life backward: start with the pebble in your hand and end with the mountain it came from. Angle: with every step back in its weathering, it gets bigger and sharper.
  • Write a thank-you note from a handful of soil to the rock it used to be. Fact: what is left after weathering breaks rock down mixes with organic material to make soil.
  • Write the autobiography of a grain of sand that used to be part of a cliff, before weathering and erosion got to it. Angle: tell it in three homes: the cliff, the river, the beach.
  • You are a rock that ice has just split in two. Write the first conversation between your halves. First line: Well. This is new.

The river's work 15

  • A dry streambed in the desert waits months for rain. Write the hour the water comes and erosion starts again. Fact: in dry lands, running water in a flash flood can carry tremendous amounts of material.
  • A glacier carved the valley; a river moved in later. Write the river's thoughts on the old owner's taste. Fact: valleys made by glaciers may now be free of ice and occupied by streams or rivers.
  • A river bank loses a little soil to erosion every day. Write the bank's diary for the week a tree on its edge starts to lean. Angle: the river is not angry; it is just busy.
  • A river is a slow sculptor. Write the review an art critic gives of a valley the river has spent ages on. Fact: most valleys are formed by rivers or streams eroding the land over a very long period.
  • A river is asked what it does all day. Write its answer about erosion, in its own bragging voice. Fact: rivers erode the land, carry the sediment along and drop it to make new landforms.
  • A river slows where it meets a lake and drops everything erosion gave it to carry. Write the pile that grows there. Fact: after erosion comes deposition, the arrival of the material at a new place.
  • A trickle cuts a tiny canyon across a sandy beach in one afternoon. Write the afternoon as a thousand years of erosion. Angle: the first channel, the walls falling in, the fan of sand at the bottom.
  • After a flood goes down, a river leaves a layer of new mud on its floodplain. Write the mud's arrival speech. Fact: in a flood a stream overflows its banks and drops sediment on the floodplain.
  • Follow one pebble down a river from a mountain stream to the sea. Write how erosion changes its shape on the way. Fact: eroded material may travel a few millimeters or thousands of kilometers.
  • Stones in a river knock the corners off each other. Write a sharp new rock's first week in the current. Angle: it arrives with edges and opinions, and loses some of both.
  • Write a muddy river's answer to a kid who asks why it is brown today. Angle: erosion upstream; it is carrying a hillside to the sea one grain at a time.
  • Write a river's apology to the bridge whose feet it keeps wearing away. First line: I want you to know it is nothing personal.
  • Write a river's side of the story of the V-shaped valley it has been cutting since before anyone lived there. Fact: a valley cut by a river tends to be V-shaped; one carved by a glacier is U-shaped.
  • Write the work song a river sings while it wears down its bed. Angle: a verse for the sand, a verse for the gravel, a chorus for the boulders it cannot move yet.
  • Write what a river says to a hill it plans to move to the sea by erosion, and the hill's reply. Angle: the hill has patience; the river has time.

A canyon diary 15

  • A canyon has kept a diary for longer than it can count. Write what it has learned about the river that is making it. First line: It never stops, it never hurries, and it never says sorry.
  • A canyon reaches the last page of its diary so far. Write what it expects to look like after another age of erosion. Angle: deeper, wider, or both? Let the canyon guess.
  • A canyon writes in its diary about its echo. Write why the echo has gotten better over the ages. Angle: the walls moved apart so slowly that the echo never noticed.
  • A canyon's diary records the wettest spring it can remember. Write what the river took from its walls. Fact: physical erosion typically goes fastest on steeply sloping surfaces.
  • A tall spire of rock stands alone in a canyon. Write its diary entry on being the last piece left. Fact: a rock spire forms as the remnant of a butte that erosion has worn away.
  • Keep a canyon's diary for the four seasons of one year: ice in the cracks, snowmelt, a dry summer, a fall storm. Fact: water freezing in cracks and roots prying at them are both kinds of weathering.
  • The stripes in a canyon wall are like pages. Write the diary entry in which the canyon reads its own walls. Angle: what does each stripe hold: sand, mud, pebbles, shells?
  • Write a canyon's diary entry about the wind, which carves too and gets less credit than the river. Fact: in wind erosion, surfaces are worn down by the particles the wind carries.
  • Write a canyon's diary entry for a quiet day, listing every small thing weathering did while nobody watched. Angle: one grain let go; one crack took in a drop; one seed put down a root.
  • Write a canyon's diary entry for a year in which it grew by too little for anyone to see. Angle: nothing happened, and it was the usual amount of nothing.
  • Write one day in a canyon's diary twice: once as the proud canyon, once as the rock that erosion is taking away. Angle: carved or robbed? The same day, two words for it.
  • Write the canyon's diary entry for the day a slab of its wall fell in. Angle: the sound, the dust, and the river going around the new rock as if nothing happened.
  • Write the canyon's diary entry for the first time a person looked over its rim. Angle: it has been at this for ages and suddenly has an audience.
  • Write the diary of a side canyon that is dry all year except for one afternoon. Fact: arroyos, or washes, are dry stream beds that fill for a short time during rain storms.
  • Write the first entry in a canyon's diary: the day it was only a crack with a stream in it. Fact: a canyon comes from weathering and the erosion of a river over a very long time.

After the storm 15

  • A dust storm crosses a dry field. Write it as the wind's shopping trip for soil. Fact: in the kind of wind erosion called deflation, wind picks up loose particles and carries them off.
  • A puddle dries after the storm and leaves a tiny map of where the mud settled. Describe it like an explorer. Angle: deltas, islands and a shoreline, all the size of your shoe.
  • A sea cliff loses a piece in a winter storm. Write the news report as a gull would give it. Fact: wave pounding is when the sheer energy of a wave hitting a cliff breaks pieces off.
  • A single raindrop hits bare soil. Write the splash in slow motion, from one grain of soil's point of view. Fact: in splash erosion a falling raindrop makes a small crater and throws soil particles out.
  • After a storm, the path to your favorite place is washed out. Write how you would rebuild it so the next rain runs off gently. Angle: where should the water go instead?
  • After the storm a gully has opened in the hillside behind the school. Write the class meeting about what to plant there. Fact: rain erodes soil in stages: splash, sheet, rill and, most severe, gully erosion.
  • After the storm, a kid finds a rock on the beach that was not there yesterday. Write where the waves brought it from. Angle: somewhere down the coast, a cliff is missing exactly this much.
  • After the storm, the creek runs brown. Write where the brown came from and where it is going. Fact: erosion removes soil from one place and carries it to another, where it is deposited.
  • The morning after a storm, the beach is a different shape. Write what the waves took and what they left. Fact: shoreline erosion happens mainly through the action of currents and waves.
  • One garden bed is bare and one is planted. Write what each looks like after the same storm. Fact: heavy rain erodes most where the soil's surface is not well protected by plants.
  • People speed erosion up as well as storms do. Write a letter to your town about one bare patch that needs covering. Fact: human activity has raised the rate of soil erosion worldwide by 10 to 40 times.
  • Walk outside after a hard rain and write every sign of erosion you can find between your door and the corner. Angle: a fan of sand on the sidewalk, a new groove beside the path, mud on the low step.
  • Write a sandcastle's last hour as the tide and the storm waves arrive. Angle: tower by tower. Keep it funny; the builder is already planning the next one.
  • Write the before and after of a sand dune that a storm wind moved across a road overnight. Angle: the road crew arrives at dawn; the dune is not sorry.
  • Write the storm's own account of the erosion it caused, as a postcard home. First line: Arrived Tuesday. Rearranged the beach. Wish you were here.

How it works

A writing prompt about weathering and erosion has one problem to solve: nothing seems to happen. These hand the story to a rock, a river or a beach and let it run for thousands of years.

A canyon diary

Fifteen prompts are entries in one very long diary. One is the day the canyon was a crack with a stream in it; others record a wet spring, a fallen slab, the first person to look over the rim. A few written together make a canyon's life story.

A weathering and erosion writing prompt to take outdoors

The storm prompts can be checked outdoors: a fan of sand on the sidewalk, a creek running brown, a beach with a new shape. They ask where the soil went and what would hold it next time.

  • Pick a clock. A rock's story jumps a century at a time; a storm's moves by the minute.
  • Give the slow thing a rival in a hurry: a snail, a tourist, a kid waiting for a bus.

Questions and answers

What is a good writing prompt about erosion?

Follow one pebble down a river from a mountain stream to the sea, and write how erosion changes its shape on the way. Or write a sandcastle's last hour as the tide and the storm waves arrive.

What is the difference between weathering and erosion?

Weathering breaks rock down where it sits, with little or no movement. Erosion carries the loose material away by water, ice, wind, waves or gravity and deposits it somewhere else. One prompt has a rock explain this to a confused pebble.

What causes weathering?

Water above all. It freezes in cracks, and rain that has taken up carbon dioxide slowly dissolves limestone. Plant roots pry cracks apart, lichens loosen grains, and salt crystals break rock from inside.

How does a river make a canyon?

A canyon is a deep cleft between cliffs that comes from weathering and the erosion of a river over a very long time. The river cuts down through the rock and carries the sediment away downstream.
