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.

hope this helps!
The surface analysis allows one to identify and locate the large scale features of the sea level pressure field and the surface fronts. Isobars with the lowest value will encircle the region with the lowest point in the pressure field, while the closed isobar with the largest value isolates the highest sea level pressure.
B) Both are often created by the subduction of oceanic crust
C) Volcanoes and earthquakes both occur along plate boundaries
D) Volcanic eruptions open new fault lines between plates, which causes earthquakes
*DON'T ANSWER IF YOU AREN'T 100% SURE*
The earthquake and volcanoes occur in the same area and this has a 90% chance. The place where most of the volcanoes and earthquakes occurs is called as ring of the fire.
Therefore, earthquakes also occur due to the movement of tectonic plates and the same results in the formation of volcanoes. It can be concluded that "volcanoes and earthquakes both occur along plate boundaries" option C is correct.

First, you have to understand what convection is.
Did you know that the hotter something, the more it expands? This happen because heat, at an atomic level, is nothing but vibration. If a liquid is hot, it means that there is more vibration between it's atoms. And, more vibration causes to have more space between the atoms, which causes the density to decrease.
So, when a liquid has it's top cold, and it's bottom hot, the top will be more attracted by the gravity than the bottom, because it's more dense. This will cause the top to want a lot to get down, and the bottom, because of the pressure of the top, will want to go up. This will cause a spiral movement; the bigger the difference, the faster and the more violent this spiral movement will be (and that's what causes hurricanes)
So, what this has to do with Earthquakes and stuff?
The Earth, when it was formed, was really, REALLY hot. It has being losing it's heat ever since, but, since there is not air in the space, it can only lose it's eat though radiation, which is very slow. And also, the bigger something is, the slower it cools down, because there is more vibration, more movement, more energy to be lost. The earth was formed 4,5 BILLIONS of years ago. That's A LOT of time. But the lost of heat by radiation is so slow, and the earth has so much heat to be lost, that it still didn't cool down that much.
You can think of Earth like a hot potato that got out of the oven just a little ago; the outer part is already cold, but just take a bite, and you will see how HOT it's insides are. You can't take a bit out of earth, of course, but it's insides are a lot hotter that the outside, because it's the outside that loses eat. The insides have to wait for the outsides to cool down, and then lose eat to the outside.
So... we got a planet that's really hot in the inside, so hot that it's mantle is made out of liquid rocks!
So, now, it's the time to connect the dots: the upper part of the mantle loses heat faster than the inner one. This causes a spiral movement, and, since the tectonic plaques are floating in this liquid, they move as well!
When two plaques move one against each other, they crash against themselves, and this causes an earthquake. If they keep moving against each other, one will go down and the other will go up, forming a montain. If they move away, this creates an open space; and since the liquid of the mantle has, like, THE WHOLE CRUST OF THE PLANET CRUSHING IT, the mantle is craving to get out, so when there is an opening, it squirts out like crazy, creating an eruption. After a while, the magma solidifies, creating a volcano.
