Answer: An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow
The answer would be D. "I made just one request for the camping trip: I wanted to stay in a cabin instead of a tent."
Generally colons are used after phrases that are complete sentences. "I made just one request for the camping trip" is a complete sentence, and should therefore have a colon after it.
