Questions and Solutions:

#### 1. What is the line labeled A?
- Answer: Perihelion
- Explanation: The line labeled A represents the point in Earth's orbit where it is closest to the Sun. This point is called perihelion.

#### 2. What is the line labeled D?
- Answer: Aphelion
- Explanation: The line labeled D represents the point in Earth's orbit where it is farthest from the Sun. This point is called aphelion.

#### 3. What is the name of the object labeled L?
- Answer: Moon
- Explanation: The object labeled L is the Moon, which orbits the Earth.

#### 4. What is the name of Earth's movement in its orbit?
- Answer: Revolution
- Explanation: Earth's movement around the Sun is called revolution.

#### 5. How long will it take Earth to move once around its orbit from point D to point D?
- Answer: 1 year
- Explanation: One complete revolution of Earth around the Sun takes approximately 365.25 days, or 1 year.

#### 6. What date will Earth reach point F?
- Answer: June 21 or 22
- Explanation: Point F represents the summer solstice in the Northern Hemisphere, which occurs around June 21 or 22.

#### 7. What is the season in the United States when Earth is at point E?
- Answer: Winter
- Explanation: Point E represents the winter solstice in the Northern Hemisphere, which occurs around December 21 or 22.

#### 8. At what point on this diagram will Earth be closest to the Sun?
- Answer: Point A
- Explanation: Point A is labeled as perihelion, which is the point in Earth's orbit where it is closest to the Sun.

#### 9. What season will occur in the United States when Earth is closest to the Sun?
- Answer: Winter
- Explanation: When Earth is closest to the Sun (at perihelion), it is winter in the Northern Hemisphere (including the United States).

#### 10. When Earth is at point F, does the Northern Hemisphere receive direct or slanted rays from the Sun?
- Answer: Direct
- Explanation: At point F (summer solstice in the Northern Hemisphere), the Northern Hemisphere is tilted toward the Sun, receiving direct rays.

Multiple Choice Questions:

#### 1. Day and night are caused by Earth’s:
- a. revolution
- b. rotation
- c. equator
- d. axis

- a. Mars
- b. Venus
- c. Polaris
- d. Canada
- Answer: c. Polaris
