The rocks are broken into small pieces of different shapes without changing their original composition. (MEHNACLCIA)
(a)
Type of weathering that involves a change in the composition of the rock as they broke down into pieces.
(C M I L A H E C)
(a)
The repeated expansion and contraction of rocks due to this change will result in weathering.
(E R E T U M A P R T E)
(a)
Mining, use of different equipment, or simply kicking of rocks can contribute to cause weathering.
(U M A S N H)
(a)
One of the most common agents of weathering is pounding rocks that cause them to break into fragments.
(R T E W A)
(a)
The movement of rocks and soil from one place to another is called erosion.
Weathering
Erosion
Erosion of rock fragments greatly contributes to soil formation as well as formation of landforms.
True
False
What is not an agent of soil erosion?
water
wind
animals
humans
plastic
How does water causes erosion?
When soil is mixed to water, it dissolves
As water flows, its force transports rocks and soil particles from one place to another.
It doesn't contribute to erosion
The speed of flowing water affects the rate of erosion, too. The faster the water flows, the faster and the farther the erosion would be.
True
Flase
How does wind causes soil erosion?
As the wind blows, it carries light particles of rocks and soil, transporting and depositing them into another place.
As the wind blows, the particles of rock will be crushed.
It doesn't cause soil erosion
How does animal contribute to soil erosion?
Burrowing animals can carry away soil with their fur and claws
A chicken that scratches its feet on the ground causes the transport of some soil particles.
All of the above.
This agent has the major contribution to the rate of soil erosion.
Humans
Animals
Water
Gardening can cause erosion.
True
False
Weathering and soil erosion is the same.
True
False
Bonus question:
Where do you think would erosion be faster?
Which of these might be carried by the wind, which causes the weathering of rocks?
Fog
Mud
Pollen
Sand
Write at least one factor that may cause the weathering of rocks.
(a)
What is the process called when Earth’s surface is broken down into smaller pieces?
(a)
What is the process called when pieces of Earth’s materials are moved to another location?
(a)
Which of these does not cause erosion?
liquid water
ice
sunlight
wind
Sedimentary rock is formed by deposition.
True
False
Erosion ________________________.
breaks down rock
