1 Name: Date: # Weather and Climate Unit Review Directions: Complete this packet to help you prepare for your unit test by filling in the blanks to complete the definitions. Then if no picture is provided, please draw a picture that helps you to remember the meaning of the word. Vocabulary Review Word Definition Picture Atmosphere The of that surrounds the Earth. Carbon Dioxide A greenhouse that has produced the most global. Climate The average, year-after-year conditions of temperature, precipitation, winds, and clouds in an area.

2 Cold Front Cold air slides warm air This causes abrupt weather changes (i.e. ). Conduction The transfer of heat from a region of temperature to a region of temperature (usually through direct contact). Highlight this air mass in the picture below. Continental Polar A and air mass.

3 Highlight this air mass in the picture below. Continental Tropical A and air mass. Convection The transfer of heat in a (either a liquid or gas) when a higher-temperature fluid and moves.

4 Electromagnetic waves A form of that can travel through space. Flash Flood A accumulation of water on normally dry land. Greenhouse gases Gases in the atmosphere that trap (i.e. Carbon Dioxide). Hurricane A that has winds of 119 kilometers per hour or higher.

5 The cycle by which water circulates between the earth's oceans, atmosphere, and land. Condensation-Water vapor in the air cools and becomes liquid water. Hydrologic (Water) Cycle Evaporation-Liquid water that escapes into air as water vapor. Precipitation-Any form of water that falls from clouds. Surface Runoff-The flow of water that occurs when excess storm water, melt water, or other sources flows over the Earth's surface. Label the arrows above to show the steps of the water cycle. Keeling Curve A graph which plots the ongoing change in concentration of carbon dioxide in Earth's atmosphere since With an annual peak in May.

6 Highlight this air mass in the picture below. Maritime Polar A and air mass. Highlight this air mass in the picture below. Maritime Tropical A and air mass.

7 Shade the part of the graph that represents Nitrogen. Nitrogen Makes up of the gas in dry air. It is the most abundant gas. Occluded Front A warm air mass gets caught between cooler air masses. The cooler air masses move the warm air mass and push it. Shade the part of the graph that represents Oxygen. Oxygen Makes up of the gas in dry air. It is the second most abundant gas.

8 Pollutants substances in the,, or. Radiation The movement of heat. Stationary Front and air masses meet but neither is strong enough to force the other to. Thunderstorm A storm that produces and and sometimes,, and. Tornado A tornado is a rotating column of air known as a that has reached the ground.

9 Warm Front A air mass collides air mass. The warm air mass moves the cold air mass. Weather The condition of the Earth s at a particular time and place. Other things to consider as you study for this test: - Review all notes, notebook checks, skills checks, line graphs, flipped videos, and any other materials from our unit in order to prepare. - You will need to know how to analyze a line graph. - If you get stuck, remember to ask your teacher for help!

10 Answer Key-Weather and Climate Unit Review Directions: Complete this packet to help you prepare for your unit test. Vocabulary Review Word Definition Picture Atmosphere The layers of gases that surrounds the Earth. Carbon Dioxide A greenhouse gas that has produced the most global warming. Climate Cold Front The average, year-after-year conditions of temperature, precipitation, winds, and clouds in an area. Cold air rapidly slides under warm air This causes abrupt weather changes (i.e. thunderstorms).

11 Conduction Continental Polar The transfer of heat from a region of higher temperature to a region of lower temperature (usually through direct contact). A dry and cold air mass. Continental Tropical A dry and hot air mass. Convection The transfer of heat in a fluid (either a liquid or gas) when a higher-

12 temperature fluid expands and moves. Electromagnetic A form of energy that can travel through space. Flash Flood A sudden accumulation of water on normally dry land. Greenhouse gases Gases in the atmosphere that trap heat (i.e. Carbon Dioxide). Hurricane A tropical storm that has winds of 119 kilometers per hour or higher.

13 Hydrologic (Water) Cycle Keeling Curve Maritime Polar The cycle by which water circulates between the earth's oceans, atmosphere, and land. Condensation-Water vapor in the air cools and becomes liquid water. Evaporation-Liquid water that escapes into air as water vapor. Precipitation-Any form of water that falls from clouds. Surface Runoff-The flow of water that occurs when excess storm water, melt water, or other sources flows over the Earth's surface. A graph which plots the ongoing change in concentration of carbon dioxide in Earth's atmosphere since With an annual peak in May. A humid and cold air mass.

14 Maritime Tropical A humid and warm air mass. Nitrogen Makes up 78% of the gas in dry air. It is the most abundant gas. Shade the part of the graph that represents Nitrogen. Occluded Front A warm air mass gets caught between two cooler air masses. The cooler air masses move under the warm air mass and push it upward.

15 Oxygen Makes up 21% of the gas in dry air. It is the second most abundant gas. Shade the part of the graph that represents Oxygen. Pollutants Radiation Stationary Front Harmful substances in the air, water, or soil. The movement of heat waves. Cold and warm air masses meet but neither is strong enough to force the other to move. Thunderstorm Tornado Warm Front A storm that produces lightning and thunder and sometimes hail, violent winds, and tornadoes. A tornado is a rapidly rotating column of air known as a vortex that has reached the ground. A warm air mass collides cold air mass. The warm air mass moves over the cold air mass.

16 Weather The condition of the Earth s atmosphere at a particular time and place.
