Exploring Impact Craters on the Moon

Why are impact craters on the moon more visible than those on Earth?

• The moon has a thicker atmosphere that preserves craters.

• The moon has no atmosphere to erode craters.

• The moon's surface is softer, allowing craters to form more easily.

• The moon is hit by larger meteorites than Earth.

If a meteorite with a diameter of 1 km creates a crater with a diameter of 10 km, what would be the expected diameter of a crater created by a meteorite with a diameter of 2 km?

• 5 km

• 10 km

• 20 km

• 40 km

What is the primary reason that meteorites create craters upon impact?

• Their large size

• Their high kinetic energy

• Their chemical composition

• Their temperature

In an experiment to investigate crater size, which variable should be changed to study the effect of mass on crater size?

• The type of sand used

• The height from which the object is dropped

• The mass of the object

• The color of the object

How does the speed of a meteorite affect the size of the crater it creates?

• Faster meteorites create smaller craters.

• Speed has no effect on crater size.

• Faster meteorites create larger craters.

• Slower meteorites create larger craters.

Which of the following best explains why some meteorites explode on impact?

• They are made of volatile materials.

• They have high kinetic energy that converts to explosive energy.

• They are too small to create a crater.

• They are traveling at a low speed.

In the home experiment described, why is it important to smooth the surface of the sand before dropping the marbles?

• To ensure the marbles bounce off the surface

• To create a uniform surface for consistent results

• To make the experiment more visually appealing

• To prevent the marbles from rolling away

What conclusion can be drawn about the relationship between the mass of a meteorite and the size of the crater it creates?

• Larger mass results in a smaller crater.

• Mass has no effect on crater size.

• Larger mass results in a larger crater.

• Smaller mass results in a larger crater.

Which of the following is a controlled variable in the home experiment on impact craters?

• The type of marbles used

• The depth of the sand

• The height from which the marbles are dropped

• The size of the pan

How does the concept of kinetic energy relate to the formation of impact craters?

• Kinetic energy is irrelevant to crater formation.

• Kinetic energy is converted to thermal energy, melting the surface.

• Kinetic energy is transferred to the surface, creating a crater.

• Kinetic energy is absorbed by the meteorite, preventing crater formation.
