Three types of plate boundaries

divergent, convergent, transform

name of the scientist that developed theory of plate tectonics

J. Tuzo Wilson

What is created when two oceanic plates diverges

mid ocean ridge

When two continental plates collide

Mountains are formed

When two continental plates diverge

A rift valley is formed

When two oceanic plates converge what forms

ocean trench

when two plates diverge what is formed

a valley is formed

continental drift is supported by pieces of evdience like

continents fitting like a puzzle piece and the same fossils found on different contients

what is pangea

supercontinent

Why was Alfred Wegener's theory rejected?

He did not know what caused the continents to drift.

the evidence suppoorting sea floor spreading is

the reversal of the poles magnetic fields new crust being created and old crust being subducted, or pushed down into the Earth.

who developed the idea for sea floor spreading

harry hess

What is erosion?

The process in which rocks break apart from wind, sun and water

What is deposition?

The process in which bits of brown rock are transported to another place

what is the sun a driving force of?

ocean currents and atmospheric movements

Does cooler air have a higher pressure? What about warm air?

Cooler air has high pressure and warmer air has low

What has air is more denser cooler air or warmer air

cooler air is denser

What is the Coriolis Effect?

the curved path the wind follows due to the Earth's rotation on its axis

What is a doldrum?

An area of very little wind at the equator

How many convection cells are there?( due to to the uneven heating of the Earth and the Coriolis

The process of evaporation

water changes from a liquid to a gas

The process of condensation

Gas to liquid

What is carbon transfered to

through the atmosphere from processes that happen in plants and
