Constructive
What are three constructive forces?
Three of the main constructive forces are crustal deformation, volcanic eruptions, and deposition of sediment.
What was formed by destructive forces?
Weathering & erosion
What is deposition?
The process by which sediment is laid down by erosion & builds up the Earth's surface
What is weathering?
process of breaking down rock into smaller pieces
constructive
An example of constructive forces:
Earthquakes
Erosion is a destructive force that _________
breaks down existing landforms to create new ones
A change in the shape or dimensions of crust, resulting from stress.
What are the two types of weathering?
mechanical & chemical
Breaking down of landforms?
Destructive
What do constructive forces depend on?
Constructive forces depend on Earth's internal heat for their source of energy.
What is a destructive force?
The process by which rock is broken down, such as erosion and weathering either through the violent actions of volcanoes and earthquakes or by the steady flow of a river
What are volcanic eruptions?
Process by which magma reaches the surface & cools to add new rock to the surface of the earth
What is erosion?
The carrying away of broken down sediment from one place to another.
Volcanoes
What is constructive force?
