Where might you see moving water?

Oceans have waves that move. Rivers have water that flows from place to place. At home you might see moving water in the sink or shower.

Where might you see the wind move things?

If you look at the trees you can see the wind moving the leaves. If you stand outside on a windy day, you might see the wind moving loose objects like empty containers.

How can the land change over time?

Land can change from natural disasters, humans changing it, water and wind can change land as well through a process called erosion.

How could wind or water change the land around you?

Wind could blow the soil around or water from the rain could carry the soil downhill.

What happens at the beach when water meets the land?

Waves move the sand around on the beach. The waves also crush shells making them into tiny pieces that look like sand.

What happens when wind moves fast over the land?

Wind can move sand, dry soil or dust. Strong winds can carry heavier things.

How can wind change the shape of the land?

Wind can carry soil across a distance, such as sand dunes forming or being blown away. This is called wind erosion.

How can water change the shape of the land?

Water can carry tiny pieces of the Earth’s surface downstream, like how the Grand Canyon was formed by the flowing water of the Colorado River.

What are some examples of erosion?

Wind breaking down rocks and carrying the particles away is an example of erosion. You can also see how over time a river carries soil downstream and makes rocks in the river smoother.

How was the Grand Canyon formed?

Flowing water carved into the rock and carried the particles downstream. Over a long time, the river carved deeper and deeper and the Grand Canyon became how it is today.

What can help to reduce or stop water erosion?

Natural and manmade objects can block the water from eroding soil. Humans can plant grass or add mulch and stones on top of soil to keep it from moving away.

What can help to reduce or stop wind erosion?

You could plant trees to slow down the wind. You could also add plants like grass, whose roots will keep the soil in the ground.

DEFINITION OF EROSION

Erosion is when tiny pieces of the Earth’s surface are moved from one place to another. This is usually caused by moving water or wind. Erosion usually happens very slowly.

LET’S BREAK IT DOWN!

The shape of land can change over time.

The shape of land is constantly changing. You may not have noticed because it usually happens very slowly. People can slow down or stop erosion using the power of science!

Flowing water can move sand and soil.

As water flows in a river, it can carry sand and soil from one place to another. This is called water erosion and it is how the Grand Canyon was formed over a long time.

Wind can change the shape of land.

Wind is just moving air. It can blow sand and soil from one place to another. Wind can move tiny pieces of the Earth’s surface very far and very fast.

Erosion can cause major damage.

If the land beneath a house is moved away because of erosion, the house can fall down. If sand on the coast is moved away by ocean waves, the beach will be gone.

Erosion usually takes a long time.

It took a long time for the Grand Canyon to be carved by moving water. Erosion can take millions of years! It can also happen fast such as in a flood.
