• Growing more plants along a road

• A glacier moving down a valley

Volcanoes and earthquakes are both caused by:

• Erosion and weathering

• The movement of Earth’s plates

• Water moving under the Earth’s surface

How did this rock crack?

• Erosion

  The rock was carried away and split in half

• Weathering

  Water froze in a small crack of the rock, causing it to split in half.

• The rock was always like it is in the picture.

• Weathering

  A storm caused rain to spit the rock in half.

What type of weathering is in the picture?

• Biological Weathering

  Color change caused by nature

• Mechanical Weathering

  Color change caused by movement of rocks

• Chemical Weathering

  Color change caused because of a reaction to the rust on the chain

• This is not an example of weathering

What is weathering?

• The movement of rocks that have been broken down into smaller pieces by water, wind, and ice.

• The breaking down of rock ibto smaller pieces by water, wind, and ice.

• What is happening outside on any given day.

• People knocking down trees to build houses.

What type of weathering is in this picture?

• Biological Weathering

  Changes caused by nature

  (rain, snow, ice)

• Chemical Weathering

  Changes caused by a reaction to another force such as acid rain

• Mechanical Weathering

  Changes caused by the breaking down of the rock or pressure applied to the rock.

How does weathering and erosion affect Earth's surface?

(There is more than one answer)

• Makes cracks in Earth's surface.

• Changes the shape of a landform

• Rocks are broken down into smaller pieces

• Makes holes in landforms

The images show two design solutions for protecting humans from earthquakes. Assume that both structures are made from the same materials. Which solution would you choose?

• Design A

  Lower Structure

  Wide Structure

  Lots of beams to keep the structure steady

• Design B

  Taller Structure

  Narrow Structure

  Less Beams
