Name: ____________KEY__________________ Date: _______ Period: ___ 2023-2024 Earth Science Final Review Atmosphere Be able to answer the questions at the end of each chapter associated with the atmosphere, weather and climate – 17, 18, 19, 20, 21 You should be able to answer the following questions: 1. What are the layers of the atmosphere? (Be able to put them in order from top to bottom) Thermosphere (gets warmer) Mesosphere (gets colder) Stratosphere (gets warmer) Troposphere (gets colder) How does temperature change in each layer? - look over your lab or textbook p. 480 2. What are the three main types of clouds and what do they look like? If you add nimbus to a cloud name, what does that mean? Nimbus means dark rain cloud. Cumulous: Look like fluffy cotton balls with flat bases Stratus: Flat, low layered clouds Cirrus: High altitude icy clouds. Look feathery or wispy 3. What causes air to rise? What happens when it rises? Heated air expands and becomes less dense so it rises. As it rises, it cools. If it cools enough, it can reach the dew point and form a cloud; and even precipitation. 4. How does dew form? Why do droplets form on the outside of a cold glass? Air cools down to the dew point and condensation (dew) forms on surfaces. The cold glass causes the air just outside the glass to reach the dew point. 5. What are the four types of fronts? Draw how they would appear on a weather map. Understand the weather conditions for each. Cold Front: fast moving; can produce stronger storms with higher winds, maybe hail. Warm Front: Slower moving; slow steady precipitation for a day or so. Not so strong. Occluded Front: Possibly slow steady precipitation. Stationary Front: Possibly slow steady precipitation for a few days or more. 6. What are the three types of energy transfer and define them. Convection: The flow of a heated substance. (warm air rising) Conduction: The movement of heat by touch. (walking on hot sand) Radiation: Heat moving through open space. (warm of the sun on your face) 7. What is atmospheric pressure? The force that air molecules exert on a surface. 8. Explain how land and sea breezes operate. Be able to recognize one from the other. As warm air rises, cooler air slides in to take its place. 1  Name: ____________KEY__________________ Date: _______ Period: ___ 9. Understand the water cycle and all of the processes. 10.

Air pressure _decreases__ because fewer molecules are in the same space. In cold air, molecules move __closer___ together, making the air more _dense_, and air pressure increases.
