What can cause erosion to increase in an area?
Wind
The gradual wearing down by wind, water, air and natural events
Erosion
All the plants found in a particular area
Vegetation
A sudden release of energy under the Earth's surface that makes the ground shake or cracks
Earthquake
Slide 9: The plant will break the rock into smaller pieces as what happens?
The roots get longer and thicker.
A force that causes objects with mass to attract each other (to fall)
Gravity
A mixture of sand, silt, clay, rock, and humus (plant and animal remains)
Soil
Mixture of sand, silt, clay, rock and humus (plant and animal remains)
Soil
True or False:
Having vegetation in an area can slow down the amount of soil lost.
True
The breakdown of solid materials into very small particles by water, air and natural events
Weathering
The breakdown of rocks into very small particles by gravity, water, wind, and ice.
Weathering
A preserved part or trace of an animal or plant that lived in the past
Fossil
What can create sediments?
Water and ice breaking rocks into smaller pieces
The smallest unit of a substance
Particle
What happens when wind blows on a sand dune?
The pieces of sand are moved and deposited to a new location.
OR
The size and shape of the dunes change.
A design or sequence that is repeated
Pattern
Sand or small pieces of rock broken down by weathering and deposited on land or at the bottom of a body of water
Sediments
How fast the process by which water, ice, wind, and gravity transport sediments from one place to another
Rate of erosion
What is the difference between weathering and erosion?
If a rock is changed or broken but stays where it is, it is called weathering.
If the pieces of weathered rock are moved away, it is called erosion.
Stacked levels of rocks with different compositions and fossils deposited over time with the oldest layer on the bottom and the youngest at the top
Rock Layers
