Chapter 14 Lesson 1

How does weathering and erosion change the Earth's surface?

• Wind and water can carve soft rock into different shapes

• The convection currents in the mantle can cause the plates to move

• Magma reaches the Earth's surface and creates new landforms

• weathering and erosion don't change the surface of the Earth

The two types of weathering are

• sediments and rocks

• rocks and physical

• chemical and rocks

• physical and chemical

___________ weathering includes rust and cavern formation.

• Physical

• Chemical

• Sediments

• Mass wasting

One example of wind erosion is

• glaciers moving rocks to other locations

• when the wind blows sand and the dunes are constantly changing

• when the tides pull the sand from the beach out into the ocean

• when the wind blows leaves into a pile

Erosion from places with a high elevation to places with a low elevation is called

• till

• humus

• moraine

• mass wasting

Why is it important to conserve soil?

• Soil cannot easily be replaced

• Animals don't really need soil

• Soil can be easily put back if it erodes away
