Q

Erosion

A

The moving of broken up rocks

17
Q

Platforms

A

A platform created by waves mainly where the wave crashes

18
Q

Caves

A

Caves are created when a Rosian affects a non-resistant rock platforms or more resistant rocks

19
Q

Notch

A

Strong rocks on the top and weak rocks on the bottom so it makes the water go under the shore

20
Q

Cliffs

A

Cliffs are formed by erosion on resistant rocks

21
Q

Longshore drift

A

Materials moving down a shore with the wind

22
Q

Spit

A

A piece of land that sticks out from the shore

23
Q

Barrier islands

A

Stretches of land that are parallel to the main land

24
Q

The Toronto islands

A

Erosion is eating away at the shore raising the lake floor level

25
Q

Global distribution of earthquakes

A

Earthquakes happen along the edges of the tectonic plates

26
Q

Why does earth have tectonic plates

A

Earth has tectonic plates because it has a molten core

27
Q

The theory of continental drift

A

Tectonic plates move and the Continents that were once close to each other are now farther apart

28
Q

Evidence for continental drift

A

Continents look like they could fit together and there are related species on different continents

29
Q

The theory of plate tectonics

A

There are tectonic plates that move around the planet

30
Q

Causes of subduction earthquake

A

One tectonic plate going underneath the other

31
Q

Crustal earthquake

A

When the ground on top releases its energy

32
Q
