Geography

Question 1

Wegners theory

Answer 1

Wegners theory is the theory that all the continents were connected at one point

Question 2

How is the wegners theory proven

Answer 2

The same rtypss of animals were found on the borders of continents. The animals couldnt swim and had to of come from the same continent

They also fit like a jigsaw puzzle

Question 3

3 types of plate boundries

Answer 3

Convergant
Divergant
Transform

Question 4

Convergant

Answer 4

Where 2 plates collide

When this happens (usually at and oceanic and continental crusts) the oceanic moves below, thus melting the crust, lava seeps above the oceanic and creates granite, extending the continental crust

Question 5

Divergant

Answer 5

Where 2 plate move apart

This allows volcanoes to form and lava to come from the mantle

Question 6

Transform

Answer 6

Where 2 plates slide past each other

This creates earthquakes

Question 7

Convection currents

Answer 7

Found in the mantle and rotate to create divergant plates
The plates make new oceons or largen existing ones

They also keep the earth hot

Question 8

Destructive boundry:

Answer 8

Make the earth cause volcanic eruptions of earthquakes or other things

This is caused because when the oceanic plate goes under a continental plate the oceanic plate melts and due to friction this could cause lava to turn to magma, thus making a volcanic eruption

Question 9

Consructive boundry

Answer 9

They make new mountains or volcanoes

When 2 plates meet they have a chance to go up by squeezing into each other this creates volcanoes or mountains
