Soil! A natural resource found in our own backyard!!

Soil is the loose material in which plants can grow in the upper layer of Earth. It is made up

of rock, humus, air, and water.Soil is made up of 5 important components and

has 3 layers!

The 5 Components of Soil

• Humus• Sand• Silt• Clay• Rock

Page 5: Soil Vocabulary. Soil! A natural resource found in our own backyard!! Soil is the loose material in which plants can grow in the upper layer of Earth.

Sand

Sand is made up of small grains of weathered rock.

DOES NOT hold water well! Few nutrients

Silt

Made up of very small pieces of broken rock.

Sand > Silt > Clay

3 Layers of Soil!

• Topsoil• Subsoil• Bedrock

Page 9: Soil Vocabulary. Soil! A natural resource found in our own backyard!! Soil is the loose material in which plants can grow in the upper layer of Earth.

Topsoil

• This is the top layer.• It is where animals live and plants

grow.• It is a mixture of humus and rock

fragments.• It is the best layer for growing plants!

Subsoil

• Made up mostly of clay• Under the topsoil

• Not as good for growing plants

Bedrock

This is the third and bottom layer of soil. It is under the subsoil.

It is made up of weathered rock and solid rock.The worst part of soil for plant growth.

Nutrients

These are the materials that plants and animals need to grow. Do you remember where they can be found in soil?

What layer? Which components?

Weathering(breaks down)

When rocks and other materials on the Earth’s surface are broken down into smaller pieces by weather, water, and living things.

Erosion(moves it)

This is a force that gradually wears away soil and its nutrients. Can be caused by natural elements such as

wind, water, and ice. This is because of the flow due to gravity.
