The large cracks in this rock are called expansion cracks. As the overlying rock erodes away, the rock expands, causing the cracks. The cracks are an example of:
-
Erosion
No. Erosion means that the pieces of rocks are being carried away. The overlying rocks have been eroded, but the cracks are not carrying the pieces to a new location. -
Weathering
Yes! As the rocks expand unevenly, tension builds up. When there is enough stress, the rocks break. That breaking of large rocks into smaller pieces is called weathering. -
Both erosion and weathering
No. The rocks are being broken (weathering), but the pieces are staying in place, so there is not erosion. -
Neither erosion nor weathering
No. The cracks show that the rocks are breaking, which is weathering..

Which position would the Moon be in during an eclipse of the Sun?
-
A
No. In this position, the Earth would not be in the Moon's shadow. -
B
Yes! Solar eclipses only happen during a new moon, but even then, the alignment has to be just right for the Moon's shadow to fall on the Earth. -
C
No. In this position, the Earth would not be in the Moon's shadow. -
D
No. In this position, the Earth would not be in the Moon's shadow. You might get a lunar eclipse in this position, but not a solar eclipse.

When water freezes into ice, its volume increases. What happens to its mass?
-
It increases.
No. When water freezes, it takes up more space, but the mass stays the same. -
It stays the same.
Yes. When water freezes, it expands to take up more space, but its mass stays the same. Mass is the measure of how much "stuff" is there. Freezing water does not create new water or add more "stuff". It just makes the water take up more space. -
It decreases.
No. The mass stays the same, even when the water freezes. -
Water does not have mass.
No. Everything that is made out of matter has mass.

The Earth stays in orbit around the Sun because:
-
The Sun's gravity pulls on the Earth
This is only part of the answer. -
The Earth's gravity pulls on the Sun
This is only part of the answer. -
The gravity of the Sun and the Earth pull on each other
Yes! The gravitational attraction between the Earth and the Sun is a result of both the Sun pulling on the Earth and the Earth pulling on the Sun. -
Gravity does not keep the Earth in its orbit.
No. Without the pull of gravity, the Earth would continue moving in a straight path instead of curving around the Sun.

What do you have to do to replicate an experiment?
-
You do the same experiment several times.
No. Doing the same experiment several times is repetition, not replication. -
You do the same experiment that someone else did.
Yes. By replicating an experiment exactly, you should get the same results as the original experiment. -
You do an improved version of someone's experiment.
For replication, you do the experiment exactly as the original scientist did, without making any changes. -
You look for errors in someone's experiment.
The purpose of replication is to verify, not to look for errors.
