Earth Space Quiz 1 Worksheets - Free Printable

Problem Description:

The task is to solve a quiz about Earth and Space by selecting the correct answer for each question. The quiz involves terms related to celestial objects, astronomical events, and concepts in space science.

Solution:

Let's go through each question one by one and provide the correct answer with an explanation.

#### Question 1:
Large object of matter that moves around (orbits) the sun (star).

- A. comet: A small body of ice and dust that orbits the sun.
- B. eclipse: An event where one celestial body passes into the shadow of another.
- C. galaxy: A large system of stars, gas, dust, and other objects held together by gravity.
- D. planet: A large object that orbits a star and is spherical in shape.

Correct Answer: D. planet

Explanation: A planet is a large object that orbits a star (like the sun) and is not a moon or smaller body like a comet.

#### Question 2:
A ball of ice and rock that orbits the sun.

- A. comet: A small body made of ice and rock that orbits the sun.
- B. planet: A large object that orbits the sun.
- C. constellation: A group of stars forming a pattern in the sky.
- D. equinox: A time when the sun is directly above the Earth's equator.

Correct Answer: A. comet

Explanation: Comets are known for their icy composition and orbit around the sun, often leaving a visible tail as they approach the inner solar system.

#### Question 3:
The shape of the part of the moon that is illuminated or not (when it’s in a new phase).

- A. phase: The appearance of the moon as seen from Earth, depending on its position relative to the sun.
- B. luminous: Emitting light.
- C. crater: A bowl-shaped depression on the surface of a celestial body.
- D. solar system: The sun and all the objects that orbit it.

Correct Answer: A. phase

Explanation: The "phase" of the moon refers to how much of its surface is illuminated by the sun as seen from Earth. This changes over time due to the moon's orbit.

---

#### Question 4:
The planets, the moons, meteors, and other objects that revolve around the sun.

- A. revolution: The motion of an object around another object.
- B. rotation: The spinning of an object on its axis.
- C. solar system: The sun and all the objects that orbit it.
- D. tilt: The angle at which an object is tilted relative to its orbital plane.

Correct Answer: C. solar system

Explanation: The solar system includes the sun and all the objects that orbit it, such as planets, moons, asteroids, comets, etc.

---

#### Question 5:
An astronomical event when a moon or planet passes between another planet, moon, or a star.

- A. orbit: The path of an object as it revolves around another object.
- B. solstice: The point in the year when the sun reaches its highest or lowest point in the sky.
- C. gravity: The force that attracts objects with mass toward each other.
- D. eclipse: When one celestial body passes into the shadow of another.

Correct Answer: D. eclipse

Explanation: An eclipse occurs when one celestial body passes into the shadow of another, such as during a lunar eclipse (moon passing into Earth's shadow) or a solar eclipse (moon passing between Earth and the sun).

---

#### Question 6:
The galaxy that contains our solar system.

- A. ads: Not relevant to astronomy.
- B. star: A massive, luminous ball of plasma.
- C. milky way: The galaxy containing our solar system.
- D. asteroid: A small rocky body orbiting the sun.

Correct Answer: C. milky way

Explanation: Our solar system is located within the Milky Way galaxy, which is a spiral galaxy containing billions of stars.

---

#### Question 7:
The repeating path an object takes around another object.

- A. ads: Not relevant to astronomy.
- B. star: A massive, luminous ball of plasma.
- C. tides: The rise and fall of water levels caused by gravitational forces.
- D. orbit: The path of an object as it revolves around another object.

Correct Answer: D. orbit

Explanation: An orbit is the path that one object takes as it revolves around another object, such as a planet orbiting the sun.

---

#### Question 8:
One complete orbit of earth around the sun is called a revolution.

- A. solar system: The sun and all the objects that orbit it.
- B. revolution: One complete orbit of an object around another.
- C. galaxy: A large system of stars, gas, dust, and other objects.
- D. asteroid: A small rocky body orbiting the sun.

Correct Answer: B. revolution

Explanation: A revolution refers to one complete orbit of an object around another, such as Earth completing one orbit around the sun.

---

#### Question 9:
A large hole in the ground that is shaped like a bowl.

- A. comet: A small body of ice and rock that orbits the sun.
- B. crater: A bowl-shaped depression on the surface of a celestial body.
- C. milky way: The galaxy containing our solar system.
- D. gravity: The force that attracts objects with mass toward each other.

Correct Answer: B. crater

Explanation: A crater is a bowl-shaped depression on the surface of a celestial body, often formed by impacts from meteorites or comets.

---

#### Question 10:
Rise and fall of the ocean (water level) due to the moon’s gravity.

- A. star: A massive, luminous ball of plasma.
- B. tides: The rise and fall of water levels caused by gravitational forces.
- C. crater: A bowl-shaped depression on the surface of a celestial body.
- D. meteoroid: A small rocky or metallic body in space.

Correct Answer: B. tides

Explanation: Tides are the periodic rise and fall of water levels in the ocean, primarily caused by the gravitational pull of the moon and, to a lesser extent, the sun.
