the motion of continents
B.
earth's orbit around the sun
C.
how seismic waves travel
D.
the size of volcanoes on the earth’s surface
The correct answer is C. How seismic waves travel
Explanation:
The Earth is composed of different layers that include the crust, the mantle, the outer core and the inner core, each of these layers and the features of them have been discovered throughout the years by topographers, and other experts mainly by studying seismic waves. This can be explained as seismic waves that occur due to earthquakes, eruptions, explosions and other phenomena, travel through the different layers of Earth and depending on which layer they are they display different features and speed which is the main information scientists used to determine the layers of Earth and other features of Earth's interior. Thus, it is how seismic waves travel the one that provides scientific data about the earth's interior.
Iceland is a country that is located right above a mid-ocean ridge. This actually makes the country being divided in two parts geologically speaking, as the western half is part of the North American plate, while the eastern half is part of the Eurasian plate.
Iceland has formed because of intense volcanic activity at the mid-ocean ridge in the North Atlantic Ocean. As more and more magma has been propelled at the divergent boundary, the mid-ocean ridge has been growing in size, and over time it gradually became so high that it came out above the surface of the water.
The volcanic activity has continued, and it still is, and the volcanic eruptions constantly provide new lava flows, which create new crust, thus solidify the island and make it a long lasting one, not allowing the erosion to gradually level it and destroy it.
