What are impact craters evidence of?

• The existence of water on celestial bodies

• The age of the solar system

• Collisions that have happened in the universe

• The presence of life on other planets

What factors determine the size and shape of impact craters?

• The color and temperature of colliding objects

• The mass and speed of colliding objects

• The distance from the sun and the presence of an atmosphere

• The age of the celestial body and its rotation speed

Why is it harder to find craters on Earth compared to the Moon?

• Because Earth is larger than the Moon

• Because of Earth's weather and plants

• Because the Moon has more craters

• Because Earth's craters are smaller

How does the angle of impact affect the shape of a crater?

• It does not affect the shape at all

• It determines the color of the crater

• It affects the crater shape

• It changes the size of the crater only

Which celestial body is known to have a lot of craters?

• Venus

• Mars

• Earth

• Moon

What was the original state of matter according to Kant's Nebular Hypothesis for the formation of the solar system?

• A) A small, dense core

• B) A giant cloud of dust and gas

• C) A series of small, disconnected particles

• D) A solid mass

According to Kant's Nebular Hypothesis, how did particles in the early solar system begin to form clumps?

• A) They were randomly distributed without any attraction.

• B) They were pulled into orbit around a central object.

• C) Attractive forces between particles made them stick together.

• D) They collided at high speeds and fused together.

What was a limitation of Kant's Nebular Hypothesis in explaining the formation of the solar system?

• A) It could not explain the presence of comets.

• B) It did not explain the formation of stars.

• C) It did not explain the orbits of planets.

• D) It could not account for the different types of planets.

According to Pierre-Simon Laplace's refinement of Kant's model, what did the cooling and compacting of the sun lead to?

• The sun began to spin slower.

• The sun's rotations became faster.

• The formation of multiple stars.

• The expansion of the matter cloud.

What did Laplace state would happen to the matter cloud as a result of the sun's movement according to his hypothesis?

• It would disperse into space.

• It would form a spherical shape.

• It would flatten into a disc called the protoplanetary disc.

• It would condense into a single planet.
