A) The strong ocean currents are undermining both areas causing earthquakes.
B) Both areas are subjected to strong ocean wind and waves that causes earthquakes.
C) Both areas are located near the edge of the Pacific Ocean, the unstable sand causes earthquakes.
D) Both areas are on the boundary of active plate margins, the motion of the plates causes earthquakes.

I don't know what you're trying to say about number 2. As for the rest the answers are somehow D. Looks sketchy, but to the extent of my knowledge those are the answers.

2: D

3: D

4: D

5: D

Explanation:

1. In some areas of the world, like California and Japan, earthquakes are a common occurrence. How can this best be explained?

  • The surface of the Earth is formed by tectonic plates. These plates sometimes move and the friction between the edges generate the earthquakes.

2. In the diagram of the ocean basin, where is the oldest oceanic crust found?

  • The surface of the Earth is formed from the liquid magma that comes out from the center, through the volcanoes. So, the surface furthest from the volcano is the oldest.

3. When an experiment is repeated and the new results are different from the original results, what could you assume to be true?

  • To get a conclusion, from an experiment, you have to repete it many times and see what is the result that repeted. You can not draw conclutions from one or two results.

4. Which piece of lab equipment has specific markings for highly accurate measurements of liquid volumes?

  • The graduates cylinder, made from glass or plastis, it's transparent and lets you see precisely where the liquids are.

5. Which question can be answered by an experiment?

  • Cancer is a multi-causal disease. You can't, through an experiment, say that its generated by replacing sugar.
  • You can guess about what kill them all, but not by an experiment.
  • Again, you can guess or do a reserch about it but you can't do an experiment.
  • Hunta Virus is a disease, so you could took a group of people and expose them to this disease and see if all of them got it.
