Atmosphere, Oceans, and Weather

QuestionAnswer
How is heat moved around the world? The sun
Why do we have seasons? The Earth's inclination on its axis and the distance of the Earth from the Sun.
Why are the poles cold and the equator warm? The sun is over the equator
Explain the water cycle. Water evaporates, vapor rise and condense into clouds, the clouds move over land, precipitation falls, water fills the streams and rivers, and then back into the ocean.
Why does the wind blow from the ocean to the beach during the day? The sun heats up both land and water. The air is hotter above the sea than the land. The air pressure at the water is higher and flows to the lower pressure.
How does the wind blow from the ocean to the beach during the night? Land to the sea
Where does most of the evaporation on Earth take place? Over the Oceans
How do high and low pressure areas affect wind?

How do high and low pressure areas affect wind? Air flows from high pressure to low pressure.
Explain low pressure characteristics of air. High winds, warm air, clouds, precipitation
Explain high pressure characteristics of air. No clouds, High temperatures and lower low temperatures
What is a front? The boundary separating two masses of air of different densities.
What is an air mass? A volume of air defined by its temperature and water vapor content.
How are characteristics of air masses determined? By the source region, which is the surface area over whichthe air mass originates.
What is a cold front? The leading edge of a cooler mass of air, replacing a warmer mass of air. Moving from NW to SE with cold, dry air.
What is a warm front? The transition zone where a warm air mass is replacing a cold air mass. Moving from SW to NE with warm, moist air.
What layer of the atmosphere does weather occur in? Troposhpere.
What measures air pressure? A barometer
What measures wind speed? An anemometer
Which way do prevailing winds blow 30 degrees north and south on Earth? The winds push back to the equator.
Where do warm currents originate? Near the equator
Where do cold currents originate? Polar region

Where do cold currents originate? Polar region
Why do we have strange weather in Texas? Texas is 30 North of the Equator and winds push back to the equator
How do ocean currents regulate climate? North or south currents have warm or cooled water that can warm or cool the air.
Why do we have strange weather in Texas? Texas is 30 North of the Equator and winds push back to the equator
How do oceans regulate the temperature of the Earth? Oceans cover about 70 % of Earth's surface and can store and release a lot of heat.
How does elevation affect temperature? Temperature falls 1.6 degrees for every 1000 feet high.
How does elevation affect temperature? Temperature falls 1.6 degrees for every 1000 feet high.
Name all of the effects of El Nino. Wet in the midwest
Name all of the effects of La Nina Dry in the midwest
How do hurricanes get their power? From the evaporation from warm ocean water
What do you think would happen if the ocean's temperature increased? Ice would melt, global warming
Can you draw a warm front and a cold front on a map? yes or no?

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
