what affects climate in landlocked areas?

Elevation and terrain

What is the wind section in the same area as the poles called?

Polar easterlies

Which direction are Polar easterlies coming from?

east

What are the two sections closest to the equator from 30S-30N called?

Trade Winds

what is the section between the Trade winds and Polar Easterlies called?

Westerlies

How are convection currents caused?

The sun heating certain areas of the globe certain amounts, causing differences in temperature and constant movement of air/wind

Down-welling

When denser water sinks (cold and salty) to the bottom of the ocean to replace less dense (nutrient filled) water which rises to feed fish, plants, etc.

Current

Continuous flow of water that travels predictably, many currents create the global conveyor belt.

Surface current

A current on the surface of the ocean created by global winds

Density currents

The act of denser water sinking, and less dense water rising creating currents in the ocean.

Salinity

Measure of how much ice is in the ocean

warm currents are on which side?

East

Cold currents are on which side?

West

Cold currents are pushed ______ the equator

Towards

Climate

the weather conditions prevailing in an area in general or over a long period.

Weather

the state of the atmosphere at a place and time
