S3.D.1.3.1 S3.D.1.3.1

Identify ways that cause Earth’s surface to be constantly changing (e.g., wind and water erosion, contraction and expansion of surfaces).

Activities

Define weathering.

Define erosion.

Weathering and erosion are both ways the earth is slowing changing. Identify one natural event that may change the earth’s surface quickly.

Predict how ice can affect the Earth’s surface.

Compare and contrast wind and water erosion.

Hypothesize whether or not living things can cause erosion.

Answer Key/Rubric

Weathering is when rocks are broken down into smaller pieces.

Erosion is defined as the process of which something is worn away.

Acceptable responses may including, but are not limited to:

Earthquake

Mud/land slide

Volcano eruption

Tsunami

Acceptable responses may include, but are not limited to:

Water can get into cracks in rocks and turn into ice.

As water freezes it expands.

As the ice gets bigger, it will force the crack to get larger and could eventually dislodge part of the rock

Acceptable responses may include, but are not limited to:

Both wind and water erosion change the surface of the Earth.

Wind erosion happens in drier climates when the wind picks particles up.

Wind can erode hills and mountains by wearing away at the surface

Water erosion can happen from rivers, lakes, and oceans or from flooding.

Water can wear away at the surfaces, and carry these particles to make different landforms.

Acceptable responses may include, but are not limited to:

Living things can cause erosion.

Plants roots can break apart soil and rocks.

Insects move soil around.

Animals with claws can move soil around.
