What are ocean ridges.
100
This is what is known as the distance from one crest to the next.
What is wavelength.

This can be described in terms of temperature, wind speed and direction, air pressure, and moisture (precipitation).

What is continental shelf.
200
This is when a wave collapses onshore in a tumble of water.
What is a breaker.
200
This is when it takes a large amount of heat to increase waters temperature a small amount.
What is specific heat capacity.
200
These areas of land is a lowland area that is saturated water for part or all of the year.
What are wetlands.
300
These are the large pieces of a glacier that break off and crash into the ocean.
What are icebergs.
300
These are the wide open features between the high mountain ranges at the center of the basin and the beep trenches at their edges.

400
Also known as a watershed this is an area of land that drains into a body of water.
What is a drainage basin.
400
This uses sound waves to probe the seabed.
What is sonar mapping.

Referred to the process of heat transfer in the air.
What is convection.
400
This is an area of wetland that builds up where a river meets the ocean.
What is an estuary.
500
When water does not soak into the ground or evaporate, but instead flows across the Earth's surface.
What is run-off.
500
This forms when an oceanic plate collides with a continental plate, the denser ocean plate is forced to bend steeply down beneath the less dense continental plate.
What is a trench.
