  7. 7Theory 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?
    1. AEarth's tectonic plates have very slowly moved over a long period of time. They used to be pushed together in one large continent, called Pangaea, but over time, the continents drifted apart to where they are today. They are not likely to move any further apart or closer together over the next few million years because the process has stopped. Fossil evidence proves the continents were once pushed together.
    2. BEarth's tectonic plates float around on the mantle because of convection currents. They used to be pushed together as one large continent, called Pangaea. Over millions of years, the continents have drifted apart to their current positions. One major piece of evidence to support this theory are the fossils found and the shapes of the continents that seem to fit like puzzle pieces. Over the next few million years, the continents will continue to drift apart in places and drift closer together in other places.
    3. CAlfred Wegener figured out that Earth's tectonic plates were moving around and called the idea continental drift. He realized this process happens very quickly, so over the next hundred years or so, North America will probably be touching China because of the convergent plate boundary around the Pacific Ocean.
    4. DContinental drift is the idea that explains how earth's continents have pushed together to their current positions, which is called Pangaea. Alfred Wegener was the person who proposed the idea that fossils change as the continents move around. By working with Charles Darwin, Alfred Wegener was able to figure out how Pangaea happened from convection currents by studying fossils.
  8. 8Lithosphere: 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?
    1. AAll of Earth's Land
    2. BAll of Earth's Water
    3. CAll of Earth's Living Things
    4. DAll of Earth's Air
  9. 9Water 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?
    1. AChemical only.
    2. BPhysical only.
    3. CBoth chemical and physical
  10. 10What was the total distance this plane flew?Imagen de la pregunta 10
    1. A200 km
    2. B0 km
    3. C400 km
    4. DNone of these
