1. EARTH’S LANDFORMS
CHAPTER 1
LESSON 1

2. LANDFORMS Landforms are the shape of a part of Earth’s surface.
Examples of landforms:
Plains
Mountains
Hills

3. PLATE TECTONICS
This is the theory that Earth’s surface is divided into several major, slow-moving plates or pieces
When the plates push together, their edges may fold creating mountains.

4. CONTINENTAL DRIFT This is the movement of the continental plates.
Scientists believe that Earth’s landmasses were once a supercontinent known as Pangaea.

5. FAULT A break in the Earth’s crust where movement occurs
Earthquakes are most commonly found along faults.

6. MAGMA
Melted rock within the Earth

7. LAVA
Magma that has broken through Earth’s crust and is on the surface

8. WEATHERING
The process of breaking rocks into smaller pieces through heat, water, or other means
There are many different types of weathering such as wind, water, and ice.

9. EROSION The natural process of moving sediment
It shapes the Earth’s surface.

10. DEPOSITION
The process of dropping, or depositing, sediment in a new location

11. FLOODPLAIN
A landform of level ground made up of sediment deposited by a river or stream

12. DELTA
A triangle-shaped piece of land built from soil deposited at the mouth of a river

13. How do people change the land?
By building farms
By building cities
By planting crops
By reshaping waters and creating new ones
By draining water from wetlands to create dry land for cities and farms
