What is the main cause of air movement around the Earth. Answer

Differences in temperature Home

The Coriolis Effect is when winds curve instead of moving in straight lines. What causes this to happen? Answer

The rotation of Earth on its axis. Home

What do cooler temperatures do to the air to cause wind? Answer

Cooler air is more dense and sinks, warm air moves in above the cool air. Home

What commonly causes ocean breezes on the coast? Answer

When the water and land is heated at different speeds Home

Answer

The Sun Home

The main reason air moves around the Earth is… Answer

Differences in temperature between air masses Home

Thunderstorms often happen when cooler air forces underneath warm air. The line where the storms move through is called… Answer

A cold front Home

What will form when a large lowpressure air mass meets a large highpressure air mass? Answer

A front will form Home

What are the properties that describe a cold air mass? Answer

High pressure and high density Home

What do we call the measure of the amount of water vapor in the air? Answer

humidity. Home

A rapidly rotating cloud that forms over land causes destruction over a multi state area. Answer

tornado Home

Which storm is longer lived, larger in size and generates more rainfall: tornadoes or hurricanes? Answer

Hurricanes Home

Why do hurricanes lose energy when they travel on land for a few days? Answer

The air above the land is dry and cooler than the ocean where it forms. Home

Why don’t hurricanes form near the cold dry air of the polar climate zone? Answer

Hurricanes need warm and moist air that is found at the equator. Home

What causes hurricanes to move to the east after moving onto land for several days? Answer

Global winds or Coriolis effect Home

Why do coastal towns have a smaller temperature range from coldest to warmest of the year? Answer

The temperature of the coastal towns is influenced by the slow changing ocean temperatures. Home

The change in temperature and humidity of a small area over a few days is called. . Answer

weather Home

The average temperatures and humidity levels of a large area over time, that is influenced by its closeness to oceans and distance from the equator or poles. Answer

climate Home

What causes the temperatures at the equator to stay nearly the same all year? Answer

The sun’s angle stays directly overhead all year at the equator. Home

An air mass that blows down to the United States from Canada would have which name: a. Maritime tropical b. Continental polar c. Continental tropical Answer

continental Polar c. P Home

Where does the energy come from that causes weather on our planet? Answer

The Sun Home

What type of thermal energy transfer best describes how the surface of the Earth is heated by the Sun? Answer

radiation Home

What causes high tide and low tide in the Earth’s oceans? Answer

The pull of the moon’s gravity Home

What characteristic of Earth is responsible for the seasons? Answer

the tilt of its axis Home

How does the tilt of the Earth’s axis affect differences in daylight and weather at the poles? Answer

Since the Earth’s axis is tilted, the poles are farther away from the sun in winter and the light is spread out over the land, closer to the sun in summer, more daylight. Home
