Semester 1 Exam

heat transfer

• a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.

• the movement of energy from a warmer object to a cooler object

• thermosphere

• a layer in the stratosphere (at approximately 20 miles) that contains a concentration of ozone sufficient to block most ultraviolet radiation from the sun. Absorbs energy from the sun causing temps to rise.

• decrease

• heat

The temperature of a metal spoon will ________ because heat energy from the boiling water will transfer to the spoon.

• increase

• The outermost layer of Earth's atmosphere, contains ionosphere, temperature increases, pressure is the lowest

• Energy that is radiated or transmitted in the form of rays or waves or particles. Comes from the sun.

• decrease

Troposphere

• An underwater mountain chain where new ocean floor is formed

• The layer of Earth's atmosphere where most jets are found

• The lowest layer of Earth's atmosphere and where most weather occurs.

• differences in water density. (Causes convection currents: warm rises while cold sinks)

________ flows from the hot object to the cold object and can cause an object's temperature to change.

• heat

• 12 to 50 km, Ozone held here, absorbs UV radiation, second layer from earth.

• warm

• A gently sloping, shallow area of the ocean floor that extends outward from the edge of a continent

Stratosphere

• The direct transfer of heat from one substance to another substance that it is touching.

• a steep incline of the ocean floor leading down from the edge of the continental shelf

• 12 to 50 km, Ozone held here, absorbs UV radiation, second layer from earth.

• 1% because the other 97% is salt water and 2% is groundwater and glaciers/ice .
