Entry Task Monday, March 24th For problems 1-3, Decide if the statements are true. If they are write them out as is. If they are false, correct the statement. 1. The gas that varies from 0%-4% in Earth’s atmosphere is nitrogen. 2. The Coriolis effect influences air motion across Earth’s surface 3. The changing of a gas to a liquid is evaporation. Problem 4, answer IQIA 4. Based on the reading/RSG you did for 17.1, why do you think we are reviewing the above information? Schedule: • 17.1 notes Objective: • I can understand that weather changes as air masses move Homework: • 17.1 Review Questions- page 581 #1-6. Answer using full sentences, IQIA. Please have on desk: • 17.1 RSG Weather Changes As Air Masses Move Air Masses Are Bodies of Air That Move Through The Atmosphere • Air Mass – A large volume of air in which temperature and humidity are nearly the same in different locations at the same altitude. • An air mass forms when the air over a large region of Earth sits in one place for many days. The air gradually takes on the characteristics of the land or water below it. • Earths surface can affect the air on Earth. The Four Types of Air Masses • Continental air masses form over land. Air becomes dry as it looses moisture. • Maritime air masses form over water. Air becomes moist as it gains water vapor. • Tropical air masses form near the equator. Air becomes warm as it gains energy from the warm land or water below. • Polar air masses form far from the equator. Air becomes cool as it loses energy from the cold land or water below. How Air Masses Move • Air masses can travel away from the regions where they form. They move with the global pattern of winds. • When an air mass moves to a new region, it carries along its characteristic moisture and temperature. Cold Front • Front – A boundary between air masses. • Cold fronts can move into regions quickly. A front is steeper then any other fronts. Cold fronts often produce cumulonimbus clouds, which can cause heavy storms. Cold Front Warm Front • Warm fronts move more slowly than cold fronts. Warm air moves up and over a mass of denser and colder air. As a warm front approaches, you may first see high cirrus clouds, then stratus clouds, then lower stratus clouds. Often a warm front brings many hours of steady rain or snow. Warm Front Stationary Front • Stationary fronts occur when air masses first meet or when a cold or warm front stops moving. For a while the air masses stay in the same location. If the air pushes up it may produce clouds that cover the sky. Stationary Front Pressure Systems • High-pressure system is formed when air moves all the way around a high-pressure center. Generally brings clear skies and calm air or gentle breezes. • Low-pressure system is a large weather system that surrounds a center of low pressure. Usually develops between a warm air mass and a cold air mass. Entry Task Tuesday, March Write your objective and homework down and then clear your desk off.
