WG: 3.1 & 3.2

Compare/contrast weather to climate.

• Weather is the long-term average of atmospheric conditions; climate is short-term.

• Weather is short-term atmospheric conditions; climate is the long-term average.

• Weather and climate are the same.

• Weather is the study of stars; climate is the study of planets.

What is the Earth's axis?

• The axis is an imaginary line through the Earth's center; it affects seasons.

• The axis is a real line on the Earth's surface; it affects gravity.

• The axis is a line that changes daily; it affects the moon phases.

• The axis is a line that causes earthquakes; it affects tectonic plates.

Earth's Rotation: In which direction does the Earth rotate, how long does it take to complete a rotation, and how can this impact the temperature on Earth?

• Earth rotates east to west; it takes 48 hours.

• Earth rotates west to east; it takes 24 hours.

• Earth rotates north to south; it takes 12 hours.

• Earth rotates south to north; it takes 36 hours.

In which direction does the Earth revolve around the sun, and how long does it take for the Earth to complete a full revolution?

• Earth revolves clockwise; it takes 365 days.

• Earth revolves counterclockwise; it takes 365 days.

• Earth revolves clockwise; it takes 30 days.

• Earth revolves counterclockwise; it takes 30 days.

Label the Tropic of Cancer, the Tropic of Capricorn, the Equator, and the Prime Meridian.

• The Tropic of Cancer is at 0° latitude.

• The Equator is at 23.5° north latitude.

• The Prime Meridian is at 0° longitude.

• The Tropic of Capricorn is at 66.5° south latitude.

Define the Summer Solstice in the Northern Hemisphere (use Tropic of Cancer in your response).

• The longest day of the year, when the sun is directly over the Tropic of Cancer.

• The shortest day of the year, when the sun is directly over the Tropic of Capricorn.

• The day when day and night are of equal length.

• The day when the sun is directly over the equator.

Define the Winter Solstice in the Northern Hemisphere (use the Tropic of Capricorn in your response).

• The longest day of the year, when the sun is directly over the Tropic of Cancer.

• The shortest day of the year, when the sun is directly over the Tropic of Capricorn.

• The day when day and night are of equal length.

• The day when the sun is directly over the equator.

Label the Arctic Circle and Antarctic Circle.

• Arctic Circle at 66.5° N, Antarctic Circle at 66.5° S.

• Arctic Circle at 23.5° N, Antarctic Circle at 23.5° S.

• Arctic Circle at 0°, Antarctic Circle at 180°.

• Arctic Circle at 90° N, Antarctic Circle at 90° S.

Define Midnight Sun (include Arctic/Antarctic Circles in your response).

• A phenomenon where the sun is visible at midnight during summer months in the Arctic and Antarctic Circles.

• A phenomenon where the sun is visible at midnight during winter months in the Arctic and Antarctic Circles.

• A phenomenon where the sun is never visible at midnight in the Arctic and Antarctic Circles.

• A phenomenon where the sun is visible at noon during summer months in the Arctic and Antarctic Circles.

How does the Greenhouse Effect influence Earth’s surface temperature?

• It decreases Earth's surface temperature by reflecting sunlight.

• It increases Earth's surface temperature by trapping heat.

• It has no effect on Earth's surface temperature.

• It decreases Earth's surface temperature by absorbing heat.
