Radiation

2. The slant of Earth's axis, causing the North Pole to always point toward the North Star. The reason for the seasons.
5. An imaginary axle that a planet spins on.
6. Energy that is radiated or transmitted through space in the form of rays or waves or particles.
10. Caused by the tilt of Earth on its axis as it revolves around the Sun causing varied amounts of sunlight on Earth; divides our year into quarters.
11. The state of the atmosphere at a particular place and time.
13. The long-term prevailing pattern of weather.
14. Direct light in the Northern Hemisphere, warmest season.
15. Energy Energy that travels through air and space.
18. The study of a region's climate over 30 or more years.
20. Poles The Sun's rays hit Earth at a lower intensity, ~30° angle here.
21. Observable evidence of energy.

1. A scientist who studies climate.
3. Angle The angle at which the radiant energy from the Sun strikes the surface of Earth.
4. Mixture of gases surrounding Earth.
7. Shape of the Earth that causes the solar angle at high latitudes to be less than at the equator.
8. Indirect light in the Northern Hemisphere, coldest season.
9. One factor that can affect a region's climate; how far north or south a location is from the equator.
12. 0° Latitude. The Sun's rays hit Earth at a high intensity, ~90° angle here.
14. Energy Radiant energy from the Sun.
15. A thin beam or line of radiant energy, such as light.
16. To soak up or take in.
17. Star The tilt of Earth at the North Pole always points toward the North Star.
19. Energy Radiant energy that heats.
