All 25 flashcards from this kit, free and with no sign-up.
1. What causes the apparent movement of the Sun north and south?
Show the answer
The Earth's revolution around the Sun combined with the tilt of Earth's axis.
2. On June 21st, which hemisphere experiences the longest night?
Show the answer
The southern hemisphere.
3. What is the Circle of Illumination?
Show the answer
The imaginary circle that separates the illuminated (day) half of the Earth from the dark (night) half.
4. Why are days and nights equal at the equinoxes?
Show the answer
Because the Sun's rays fall perpendicularly on the equator, so the Circle of Illumination passes through both poles.
5. What is perigee?
Show the answer
The point in the Moon's orbit when it is closest to the Earth.
6. What is apogee?
Show the answer
The point in the Moon's orbit when it is farthest from the Earth.
7. What is an eclipse?
Show the answer
The partial or complete hiding of one celestial body by another, such as the Sun or Moon.
8. What causes high and low tides?
Show the answer
The gravitational pull of the Moon and the Sun on the Earth's water.
9. What are spring tides?
Show the answer
Tides with the largest tidal range, occurring when the Sun, Moon, and Earth are in a straight line (new moon and full moon).
10. What are neap tides?
Show the answer
Tides with the smallest tidal range, occurring when the Sun and Moon are at right angles to each other (first and third quarter moon).
11. What is tidal range?
Show the answer
The difference in height between high tide and low tide.
12. What unit is air pressure measured in?
Show the answer
Millibars (mb).
13. What are isobars?
Show the answer
Lines on a weather map joining places with equal air pressure.
14. What is a pressure belt?
Show the answer
A zone on Earth where air pressure is consistently high or low, such as the equatorial low pressure belt or polar high pressure belt.
15. What is a barometer?
Show the answer
An instrument used to measure atmospheric pressure.
16. What are trade winds?
Show the answer
Steady winds that blow from the subtropical high pressure belts toward the equatorial low pressure belt.
17. What are westerlies?
Show the answer
Winds that blow from the subtropical high pressure belts toward the subpolar low pressure belts, from west to east.
18. What is the Coriolis effect?
Show the answer
The apparent deflection of winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to Earth's rotation.
19. What are the Roaring Forties?
Show the answer
Strong westerly winds that blow in the Southern Hemisphere between latitudes 40°S and 50°S.
20. What is an anemometer?
Show the answer
An instrument used to measure wind speed.
21. What are the characteristics of the Tundra region?
Show the answer
Very cold climate, permafrost, low biodiversity, and vegetation like mosses and lichens.
22. What is characteristic of the Equatorial region?
Show the answer
High temperature and heavy rainfall throughout the year, supporting dense tropical rainforests with high biodiversity.
23. What is the Taiga region known for?
Show the answer
Coniferous forests with pine, fir, and spruce trees, and a cold climate with long winters.
24. What are the characteristics of Savanna regions?
Show the answer
Tropical grasslands with scattered trees, a distinct wet and dry season, and diverse wildlife.
25. What is monsoon dependency?
Show the answer
The reliance of agriculture and livelihoods on the timely arrival and amount of monsoon rainfall.
