1. Is there a relationship between the locations of earthquake epicenters, volcanoes, and plate boundaries? If so, describe the relationship. 2. According to the theory of continental drift, all of the world’s continents were once connected as one large landmass and have, over the course of hundreds of millions of years, drifted apart into the positions they occupy today. Do the results of this activity support the theory of continental drift? If so, how? Explain your answer. 3. Why is it easier to predict where an earthquake epicenter will occur than it is to predict when it will occur? Explain. 4. The Richter scale describes how much energy an earthquake releases. With every increase of 1.0 on the scale, 32 times more energy is released. How many times more energy would be released by a quake measuring 2.0 more units on the Richter scale? 5. Why do you think the area around the Pacific Plate is called the Pacific Ring of Fire? 6. The Hawaiian Islands have formed as the Pacific Plate moves northwestward over a hot spot of Earth’s interior that provides magma to form several volcanos. Explain what could happen if the Pacific Plate continues to move. 7. How can volcanic eruptions be predicted?

1Earthquakes occur along fault lines, which are all the types of plate boundaries.

Volcanoes are located along converging plate boundaries and diverging plate boundarie

2Yes. The reason that earthquakes and volcanoes occur is the plate moving. The magma rises and pushes the

both-side crust. That causes continents moving and volcanoes and earthquakes happen.

3Now people know earthquakes happen along the plate boundaries, so they can predict where it is going to

happening. However, they cannot know when it happens. People cannot predict when the plates are going

to move.

4 64 time more

5There is the area that volcanoes and earthquakes happen usually.6

6Those formed islands are going to keep moving northwesrward and the magma from the hotspot will rise,

cool, and form a new island.

7Before an eruption, magma will rise toward the surface and break the rocks. That causes the hotter surface

and an earthquake. For these two reasons, people can predict volcano eruptions.

answer: option d : 3.85 units

step-by-step explanation: in the given figure the blue line is diameter   .the diameter is the blue line which equals 7.7 units.radius is half of diameter .radius = 7.7÷2=3.85 units.

option d is the right answer.
