Earth Science

What is the name of the theory that states Earth's crust is broken into many pieces that float around on the mantle (or sometimes stated as floating on the asthenosphere)?

What process or processes would cause a big, tall mountain to become a much smaller mountain or hill over thousands or millions of years?

Which of the following is the name of a break in rock that could rearrange rock layers so that they no longer line up in neat rows?

If you see rocks that look like they have been pushed together in ribbon-like layers, such as in the diagram below, what process would cause this change in the rock layers?

Which rock layer below most likely is the newest or youngest?

Which of these rock layers would be most the most likely to be made up of sedimentary rock?

Theory of Pangaea: In the early twentieth century, a scientist named Alfred Wegener noticed that, if you cut the continents out of a map, they would fit nicely together into one large super continent. He named this super continent, Pangaea. He predicted that Pangaea existed about 200 million years ago. Using that time period, he looked at what animals lived during that time and began to search for fossils on each continent. He was able to find fossils of the same kinds of animals on both continents where they would have been joined so his theory was supported. However, the best supporting evidence wasn’t found until the 1060’s. The idea of continental drift, where tectonic plates move around on Earth's mantle, explains how the continents have ended up in their current positions. Based on this information, which of the following is a true statement?

Lithosphere: The outer crust of the earth is known as the lithosphere and it is composed of the seven large plates and many smaller pieces. These are all known as tectonic plates. In Wegener’s theory, Pangaea broke apart and the pieces started moving over the earth’s surface and into their current locations. In fact, the plates are still moving and, if you could revisit the earth in a few million years from now, you would notice that the continents are not in exactly the same places they are today. Tectonic plates move because of convection currents within the mantle. As hot magma moves up, it starts to cool and sinks back toward the core where it heats back up, lowering the density and causing it to rise and cool again. What is the lithosphere?

Water on Earth is always changing. Its repeating changes make a cycle. As water goes through its cycle, it can be a solid (ice), a liquid (water), or a gas (water vapor). Ice can change to become water or water vapor. Water can change to become ice or water vapor. Water vapor can change to become ice or water. What type of change is this when a substance changes from a solid to a liquid or a liquid to a gas?

What was the total distance this plane flew?

Look at the graph above. In this experiment, what was the dependent variable?

According to this graph, which of the following would be the BEST conclusion to the experiment?

In many locations the hot molten magma from deep within the Earth rises up through the crust to reach the surface. This sometimes happens in the middle of plates. When a hot spot forms in the middle of a plate, it remains constant, as the plate continues to move over it. The result is that a trail of volcanoes is left behind, with older volcanoes moving away from the hot spot, and newer ones forming over top of the hot spot. What moves to form a hot spot volcano?

What is the difference between a fault and a fold?

Which processes are considered destructive?

Which type of plate boundary forms folded mountains?

What causes seafloor spreading?

What kind of plate boundary makes a subduction zone and often makes big earthquakes?

What causes seafloor spreading?

What kind of plate boundary makes a subduction zone and often makes big earthquakes?

The India Continetnal Plate is constantly pushing north up into the Eurasian Continental Plate. What kind of plate boundary is this, and what kind of landform is being created?

What is the place beneath earth where rock breaks and sends out seismic waves in all directions from the point where the rock broke to cause earthquakes called?

Which type of plate boundary is considered a constructive Earth process as new igneous rocks are being formed?

Which part of the water cycle happens when water RELEASES thermal energy?

Which of the following is the correct definition for density?

What are the two main things that make a metamorphic rock?

This diagram shows many of the processes that change rocks from one form to another. Uplift is a term that refers to rocks being pushed up from faulting or folding of rock. Weathering breaks down rock. Extrusive igneous rock will form on the OUTSIDE of the volcano from cooled lava as it erupts. The intrusive igneous rock forms from cooled magma inside earth. What process provides the transportation of rock down the mountain?
