Constructive Forces
These build up or create new landforms
What are constructive forces?
These are the three main agents of change (you must name all three!)
What is water, wind, and ice?
These have roots that will grow into rocks and break them down
What are plants?
These are natural processes that wear away or break down the Earth's surface
What are destructive forces?
A natural shape or area on the Earth's surface that we can see
What is a surface feature?
This force drops materials like sediment and soil
What is deposition?
This agent of change can create canyons by eroding sediment from river banks
What is water?
When small animals burrow in the dirt and loosen the soil it has this effect
What is weathering?
These include things like hurricanes, earthquakes, tsunamis, and tornadoes
What are natural disasters?
The type of practices that led to the creation of Providence Canyon
What are poor farming practices?
These are created on beaches by the force of deposition
What are sand dunes?
These two agents can smooth a rock's surface (you must name both)
What are wind and water?
This Georgia landmark was created by nature after humans altered the landscape, leading the way for its creation
What is Providence Canyon or the Little Grand Canyon?
This force is responsible for creating the Grand Canyon using the Colorado River
What is erosion?
Small particles of rock and soil that can be transported by wind or water
What is sediment?
This constructive force may build new land out of volcanic rock
What is volcanic activity?
Accumulations of dirt and rocks that have been pushed along by a glacier and deposited when the glacier melts
What are moraines?
Clearing land which removes the roots and structure of landscape causes this force to more easily occur
What is erosion?
This force breaks down rocks into smaller pieces through physical or chemical means
What is weathering?
The term for something that was not created by humans
What is natural?
These are created when tectonic plates shift
What are mountains?
This is when water seeps into cracks in rocks and freezes which causes rocks to break over time
What is ice wedging?
These three activities caused by humans can lead to rapid changes in the earth's landscape (name all three)
What are construction, mining, and agriculture?
During erosion, this agent scrapes away mountains and carries rocks with it as it moves
What is ice?
These make Providence Canyon unique to Georgia and interesting for scientists to study
What are colorful soil layers?
