Earth Science 15-13 (pages 520-526)

Climate is mostly determined by these two factors:

• Time of year and lengths of day

• Temperature and the amount of precipitation

• Pressure and humidity

• Solar energy and seasons

(pg 520) The climate is North America is:

• mostly the same wherever you are

• often affected by earthquakes

• has a lot of variation

• Is very similar to most of the other continents

(pg. 521) The sun strikes the Earth's surface at different angles because:

• The earth's surface is curved

• The earth orbits on its axis

• The sun moves from East to West through the day

• The Earth is not a perfect sphere.

Lines of latitude measure distance

• north or south from the equator

• East or west from the equator

• from the sun

• above or below sea level

( pg. 521) At 90 degrees north ..

• You're at the North Pole

• You're directly above the equator

• You're at the highest elevation on Earth

• You live at the place with the average summer temperature in the North.

(pg. 521) Latitude determines the amount of ______ an a place on earth receives.

• Solar Energy

• Daylight

• Heat

• Wind energy

(pg. 521) The place (s) on earth where the sun's rays hit at a 90 degree angle to the surface is:

• The North or South pole

• The equator

• The Tropic of Cancer

• The Summer Solstice

( pg. 521) The place on the earth where the sun's rays are most spread out is:

• The poles

• The equator

• Tropical Regions

• The Center of Asia

( pg. 521) When the sun's rays are less concentrated....

• Energy is more spread out so temperature is lower

• The sun's rays heat more of the land, so the temperature rise

• The ocean is able to stay warmer than the land

• The wind pattern in an area are harder to predict

The average weather conditions in a area over a long period of time is:

• temperature

• latitude

• climate

• elevation
