Science Chapter 9 Review

How do convection currents occur

a crack in the earth's curst along which movement occurs

Which type of soil has less minerals and nutrients and is light brown

the upper layer of soil

What type of fault/boundary is shown by C

the thick layer of hot dense rock just below earth's crust

What is created at a fault with the boundary shown in A

What type of weathering makes cave formations?

the lithosphere is made of what two main layers of earth?

What section of earth are the plates located in

What type of fault/boundary is shown in B

What happens when plates push together or collide

What type of landform is created at the fault with the boundary labeled C

the process by which rocks are gradually broken down

a state of rest or balance

What type of landform is created at the fault with the boundary shown in B

the melted rock inside earth

the dense center of the earth

the layer of soil under the top soil

What layer is made of solid rock

the study of how earth's lithospheric plates interact

what happens when plates pull apart or separate

a nutrient rich material made of decayed plant and animal matter

What happens when plates slide past each other

what layer is the thinnest and coolest

what main layer of earth is hottest

Why is life possible on earth?

the outermost layer of earth

contains the most nutrients, minerals, and humus

What layer of earth do convection currents occur in

Name three things deforestation has affected

the horizontal layers of material

Where do convection currents generate earth's magnetic field

What are two types of weathering

the circular movement of heated materials to a cooler area

what layer is the thickest

What type of boundary/fault is shown in A

What type of weathering causes rocks to break apart and wear away by being frozen and thawed

What type of chemical weathering produces stalactites and stalagmites?

solid layer of rock beneath the subsoil

What layer do convection currents occur in
