Earth’s Atmosphere and Pressure The Earth’s pressure ___________________as you go up in Earth’s Atmosphere rapidly decreases Which layer of Earth’s Atmosphere is 80% of the Earth’s air located in? Troposphere

Earth’s Atmosphere and Temperature True or False: the layers of the atmosphere are determined by the change of air pressure. False- it is determined by the change in temperature True or False: The temperature steadily decrease as you rise in elevation in Earth’s atmosphere. False- temperature decreases, increases, decreases, and then increases at each layer change

Global Prevailing Winds Wind blows from one direction more than any other direction The pattern of prevailing winds influences global climates- Winds move moisture and heat around the world and also produce much of our weather. Ocean and wind circulation video
