What is a constructive force?
Processes that cause the earths surface to build up.
What is formed by destructive forces
Weathering & erosion
What is weathering?
A process of breaking down rock into smaller pieces.
What is deposition?
The process by which sediment is laid down by erosion & builds up the earths surface/
Earthquakes.
Trick question : Both
What are three of the main constructive forces?
Rustal deformation, volcanic eruptions, and deposition of sediment.
What is an erosion?
It is a destructive force that breaks down existing landforms to create new ones
What is erosion?
The carrying away of broken down sediment from one place to another.
What are volcanic eruptions?
Process by which magma reaches the surface & cools to add new rock to surface of the earth.
Floods.
Destructive
What do constructive forces depend on
What is a destructive force?
Its the process by which rock is broken down, such as erosion and weathering either through violent actions of volcanoes and earthquakes or by the steady flow of a river.
What are two types of weathering?
Mechanical & Chemical
What is deformation?
A change in the shape or dimensions of crust resulting from stress.
Breaking down of landforms?
Destructive
Water, gravity, wind & glaciers.
What are destructive forces?
Its a type of force that destroys landforms
True or false : Weathering and erosion can construct landscapes.
False
What is a delta?
A land form that is formed at the mouth of a river?
Both
