Question

Does Earth become smaller or bigger when plates move?
A. Bigger. New ocean floor is continuously being formed at the MidAtlantic Ridge which means that the Atlantic Ocean is expanding.
B. Bigger. Iceland is located at the boundary between the North American plate, which moves to the west and the Eurasian plate which moves to the east. This opposing movement increases the width of Iceland approximately two centimeters every year, about one centimeter to the right and one centimeter to the left.
C. Smaller. Because subduction continuously takes place and some plates keep colliding. These form new volcanoes and mountains in the Andes and the Himalayas.
D. Neither. When new crust is created at the Mid-Atlantic Ridge, which is a divergent plate boundary, the same amount of crust is absorbed into the earth during subduction at convergent plate boundaries like the Nazca Plate subducting beneath the South American Plate responsible for the formation of the Andes Mountains, which are actively growing.​

Answer 1

Answer:

D.neither.....

hope the answer is correct...

Answer 2

Answer:

D] Neither. When new crust is created at the Mid-Atlantic Ridge, which is a divergent plate boundary, the same amount of crust is absorbed into the earth during subduction at convergent plate boundaries like the Nazca Plate subducting beneath the South American Plate responsible for the formation of the Andes Mountains, which are actively growing.​

Explanation:

1. When the plates move they collide or spread apart with each other allowing the very hot molten material called lava to escape from the mantle.
2. When collisions occur they produce mountains, deep underwater, volcanoes,etc
3. The earth do not get larger and wider when plates drift away from each other.
4. When they move, they  encounter other plates and end up diving beneath them.
5. If there is a production of a new seafloor in the mid-ocean ridge, there is also a destruction of an old seafloor at subduction zone
