b. 500 miles per hour
c. 1,000 miles per hour
d. 1,500 miles per hour

1. what tool did foucault use to demonstrate earths rotation?

a. a solar panel
b. a pendulum
c. a sundial
d. a compass

1. during winter, why do we receive less heat from the sun?

a. the sun produces less energy
b. the earth is farther from the sun

1. what happens to daylight hours as we approach the summer solstice?

a. they decrease gradually
b. they increase gradually
c. they remain constant
d. they change randomly

Explanation:

• For question 9: The Earth's tilt affects the angle of sunlight, thus changing shadow - lengths.
• For question 10: The Earth rotates at approximately 1,000 miles per hour at the equator.
• For question 11: Foucault used a pendulum to demonstrate Earth's rotation.
• For question 12: In winter, sunlight hits the surface at an angle, resulting in less heat.
• For question 13: As we approach the summer solstice, daylight hours increase gradually.

Answer:

1. b. They change based on the Earth's tilt
2. c. 1,000 miles per hour
3. b. A pendulum
4. c. Sunlight hits the surface at an angle
5. b. They increase gradually
