Constructive Processes
What is a constructive process?
Natural process that builds up Earth's surface, such as deposition.
What is a destructive process?
A natural process that breaks down Earth's surface, such as erosion.
Erosion
The process of moving soil and rock from one place to another.
What is a delta?
What is a landform created by the deposition of sediment at the mouth of a river.
How do plate movements create mountains?
When tectonic plates collide, they force the ground upward.
How does weathering affect rocks?
Deposition
The process where materials are laid down after being transported.
Formed by erosion
Canyons
Example of deposition.
The laying down of sediment in a river delta.
What is the impact of erosion on soil?
Erosion can remove the nutrient-rich top layer of soil, making it less fertile.
The breakdown of rocks into smaller pieces without movement.
Type of Surface is a sand dune?
Role do organisms play in constructive processes?
Organisms, like coral, can build structures that create new landforms.
How can human activities contribute to erosion?
By clearing land or constructing buildings, which can disrupt natural processes.
Plate tectonics
The theory that explains the movement of the Earth's plates and how they shape the surface.
Sea arches are formed...
By the erosion of rock by wave action over time.
How sedimentary rock is formed.
Through accumulation and compaction of sediment over time.
Describe how an impact event, like a meteorite strike, can change surface features.
It can create craters and alter the landscape significantly.
What is a "landform"?
A natural feature of the Earth's surface, such as mountains or valleys.
What is a volcano?
A mountain/hill with a crater through which lava, rock fragments, or gas can erupt.
