Geologists study Earth's inside using waves that spread out from earthquakes. Those are:

  1. Seismic waves
  2. Seasonal waves
  3. Selective waves
  4. Sequential waves
Show answer and solution

Correct answer: A. Seismic waves

1. The waves start at a quake or blast. 2. They travel through the interior. 3. They are seismic waves. _Source: OpenStax Astronomy 2e, Chapter 8, Earth as a Planet._

The outermost solid layer of Earth is called the:

  1. Cranny
  2. Crust
  3. Crest
  4. Cradle
Show answer and solution

Correct answer: B. Crust

1. It is the layer we walk on. 2. It is the one geologists know best. 3. That layer is the crust. _Source: OpenStax Astronomy 2e, Chapter 8, Earth as a Planet._

Oceanic crust covers roughly what share of Earth's surface?

  1. 55 percent
  2. 5 percent
  3. 95 percent
  4. 15 percent
Show answer and solution

Correct answer: A. 55 percent

1. Oceans cover most of the planet. 2. Continental crust takes the remaining 45. 3. So oceanic crust is 55 percent. _Source: OpenStax Astronomy 2e, Chapter 8, Earth as a Planet._
