The atmospheric conditions that occur from season to season and year to year with in a specific region.

The uneven heating of the earth's surface directly affects the weather.

High pressure systems create what type of weather?

Low pressure systems move counter clockwise.

Air masses sink, making it difficult for clouds to form

Low pressure systems form which of the following: (check all that apply)

Why is the ocean warmer at the equator?

Convection in ocean currents occurs when warm waters which are heated by the sun, loose their heat and then sink as they become cooler and more dense.

Warm ocean currents move towards the equator and cold currents move toward the equator.

Hurricanes form during certain times of the year when a low pressure system occurs over warm ocean waters.

Which symbol below indicates that cold air is sinking and pushing warmer air upward?

High pressure systems that push cold air downward often accumulate unstable moist air ahead of it causing severe storms.

Energy from the sun is transfered by which of the following?

Energy from the sun heats up the oceans and then is distributed throughout the Earth by distribution of convection currents.

A boundary that happens when two air masses collide but do not mix.

Which symbol below indicates that cold air meets with warm air and neither move causing a stationary front?

Which symbol below indicates that warm air is trapped by cold air creating an occluded front?

If you see this symbol approaching Houston on a weather map, what type of weather can you expect in the next 24 hours?

Meterologiest can easily forcast the direction and path of a hurricane.

The force of a hurricane dimishes as it moves over land because of loss of warm waters to fuel it's energy.

The winds of a hurricane alwsy move in a counter clockwise direction in the northern hemisphere.
