Flashcards in Chapter 9 Deck (20):
1

Earths surface is

Constantly changing

2

This landform is found along a coast--

Peninsula

3

_________ is what Earth undergoes all the time

Weathering

4

These things can cause physical weathering

Water
Ice
Living things
Temperature

5

Acid rain, a form of chemical weathering is,

Rain mixing with carbon dioxide to form an acid

6

Tell the difference and similarities between chemical and physical weathering.

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.

7

An example of erosion is

Water running downhill wears away rocks and soil.

8

Glaciers erode landforms by

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

9

Deposition can change Earths surface by

By building up new layers of land (deltas)

10

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

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.

11

Landslides and avalanches both

Happen quickly or rapidly.

12

What are some ways to control erosion?

Build barriers
Terracing
Plant trees or grass

13

A weak spot in the Earths crust where magma is forced upward and reaches the surface.

Volcano

14

Liquid that flows out of a volcano

Lava

15

A break in the Earths crust

Fault

16

Earthquakes can change surface by

Causing fires

17

Tell the similarities and differences between volcanoes and earthquakes.

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.

18

List some slow changes to Earth's surface.

Weathering - physical and chemical
Erosion and deposition

19

List some rapid changes to Earth's surface.

Erosion and deposition
