Question 4

These things can cause physical weathering

Answer 4

Ice
Living things
Temperature

Question 5

Acid rain, a form of chemical weathering is,

Answer 5

Rain mixing with carbon dioxide to form an acid

Question 6

Tell the difference and similarities between chemical and physical weathering.

Answer 6

Physical weathering changes the size of rocks only. Chemical weathering rock is broken into smaller pieces and the material that makes up the rock or soil also changes. Both types of weathering change the rock.

Question 7

An example of erosion is

Answer 7

Water running downhill wears away rocks and soil.

Question 8

Glaciers erode landforms by

Answer 8

As glaciers slide along on the water, they wear away bits of rock and soil.

Question 9

Deposition can change Earths surface by

Answer 9

By building up new layers of land (deltas)

Question 10

What is a delta? How does it tie in with erosion and deposition?

Answer 10

A delta is a fan shaped area of land. When erosion occurs, waters carry the eroded material (deposition) and drops the material elsewhere creating new areas of land.

Question 11

Landslides and avalanches both

Answer 11

Happen quickly or rapidly.

Question 12

What are some ways to control erosion?

Answer 12

Fault

Question 16

Earthquakes can change surface by

Answer 16

Causing fires

Question 17

Tell the similarities and differences between volcanoes and earthquakes.

Answer 17

Both volcanoes and earthquakes cause rapid changes to Earth’s surface. An earthquake is the shaking of Earth’s crust. A volcanoes has magma and gases.
