Earth's Layers
100
The names of the four layers of the earth, in order starting with the outer most layer.
What is the crust, mantle, outer core, and inner core?
100
The changing of materials by chemical processes.
What is chemical weathering?
100
This is the force people feel when two plates go against each other into a new position?
What is an earthquake?
100
The placing of sediments in a new place.
What is deposition?
100
Most geologists think that the movement of Earth's plates is caused by this.
What is the convection currents in the mantle?
200
This causes the plates to move.
What are convection currents?
200
The breaking down of rock into smaller pieces by forces.
What is mechanical weathering?
200
Name a CONSTRUCTIVE force of nature.
What is a volcano?
200
The destructive process which moves materials away from their place (due to gravity, water and wind).
What is erosion?
200
Earth's outermost and thinnest layer.
What is the crust?
300
The Appalachian and Himalayan Mountains were formed by which type of boundary?
What is convergent.
300
Give an example of how mechanical weathering may occur.
What is the force of gravity, ice or plant roots, animals digging.
300
This is where most Earth Features happen.
What is at plate boundaries?
300
This is how farmers can prevent wind erosion of topsoil?
What is surrounding fields with natural barriers (such as trees)?
300
This famous tourist attraction was formed when a river continued to erode rock over a long period of time.
What is the Grand Canyon?
400
CT River Valley was formed at this type of boundary.
What is Divergent
400
Give an example of how chemical weathering may occur?
What is acid rain, lichens, rust, oxidation
400
The place where two plates come together.
What is a convergent boundary?
400
These kind of forces build new features on the Earth's surface (such as mountains)?
What is constructive forces?
400
Earth's magnetic field results from movements in this.
What is the outer core?
500
This is created when a oceanic plate collides with a continental plate.
What is a subduction zone.
500
BOTH mechanical and chemical weathering accomplish this.
What is the breaking down of rock into smaller pieces called sediment?
500
This is what a crack ( a deep hole mostly found underwater) in the Earth's crust is called.
What is a fault?
500
These kind of forces wear away or tear down features on the Earth's surface?
What is destructive forces?
500
Earth's inner core is made of this.
What is a dense ball of solid metal?
