EARTH STRUCTURES STUDY SHEET
A. Review all the
materials in your science folder (when you take it home). This
includes notes, labs and work sheets. You can study for the test by also reviewing the images and videos
on this website.
B. It is important to be able to answer the following questions. You should be able to find the answers in your science folder. If the answer is not in the folder, could it be that we discussed it in class??
C. If possible, have someone quiz you on these questions. When you do answer them, make sure that you are able to give examples or draw and label diagrams whenever possible.

-
How long ago was the Big Bang?
- How did our solar system form?
- What are the names and the order of our planets from the sun?
- Approximately how old is the Earth?
- What are the three main layers of the Earth?
- Can you draw and label all the layers of the Earth? (hint: remember the class project we worked on that’s hanging on the bulletin board?)
- What is the lithosphere composed of?
-
What are tectonic plates?
- What is the difference between the oceanic and continental plate?
- In our ooblick lab, how did pressure affect the consistency of the ooblick? How does this relate to the mantle?
- Define density. Why does a ping pong ball float in water, but a rock of equal size sinks?
- Why does ice float in water? When ice melts in room temperature water, where does the melted, cold water go? Where does the warmer water in the beaker go?
- What is a convection current? Use a labeled diagram to help explain it.
- You should be able to tell me the 3 states of matter and how molecules behave in these different states.
- You should be able to explain how heat affects density. What happens to molecules as you add heat?
- Why is water wonky compared to other substances?
- Can you explain how the lava lamp works in terms of density? How is a lava lamp like the earth’s mantle?
- What heat source causes convection currents in the Earth’s mantle?
- What are the 3 main types (and 2 subtypes) of tectonic plate movement? Draw a diagram to show how each one moves.
- Why do some tectonic plates collide and form mountains, while some tectonic plates subduct underneath the other? Give examples of mountains formed by continental collision and mountains formed at subduction boundaries.
- What happens when tectonic plates move? They can cause several things to happen. What are they?
- Where are volcanoes most likely to occur?
- What and where is the “Ring of Fire”?
- Some volcanoes occur within (not on the edges of) tectonic plates. Can you give 2 examples in the United States?
- What is a hot spot in the lithosphere? How is it different from a subduction zone?
- Can you explain how volcanoes occur at subduction zones? Use labeled diagrams to illustrate.
- What causes earthquakes and where are they most likely to occur?
- Can you give an example of where two continental plates are colliding to form mountains?
- What kind of tectonic plate movement is occurring in Iceland?
- What is seafloor spreading? Where does it occur and how fast does it occur?
- What are the 4 main types of volcanoes? Can you explain the difference between them?
- What is the difference between magma and lava?
- What is a magma chamber?
-
What causes some volcanoes to be more explosive
than others? (play with the interactive that lets you make your own volcano)
- What is the main difference between how the Himalayas and Mt. St. Helens were formed?
- What causes a tsunami?
