Antarctica once belong of the Gondawa that was called a
super continent, at that time the Antarctica was surfaced with forest and had
coastal warm currents on its shores. And
when the Antarctica detach from the
continent Gondwana and moved to the south, it begin to change the waters
cooled, the temperatures dropped, the forest disappeared, and the snow begin to
covered the land then was compacted into
ice over time, all combining to create coal deposits.
The answer is D. Marine ecosystem is a region on the shores of an ocean. Air currents create more precipitation in this area than any of the others.
Answer:
A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate boundary. The rate of seafloor spreading determines the morphology of the crest of the mid-ocean ridge and its width in an ocean basin. The production of new seafloor and oceanic lithosphere results from mantle upwelling in response to plate separation. The melt rises as magma at the linear weakness between the separating plates, and emerges as lava, creating new oceanic crust and lithosphere upon cooling. The first discovered mid-ocean ridge was the Mid-Atlantic Ridge, which is a spreading center that bisects the North and South Atlantic basins; hence the origin of the name 'mid-ocean ridge'. Most oceanic spreading centers are not in the middle of their hosting ocean basis but regardless, are traditionally called mid-ocean ridges. Mid-ocean ridges around the globe are linked by plate tectonic boundaries and the trace of the ridges across the ocean floor appears similar to the seam of a baseball. The mid-ocean ridge system thus is the longest mountain range on Earth, reaching about 65,000 km (40,000 mi).
Answer:
Explanation: Cumulonimbus clouds are known as the thunderstorm clouds that gets created inside the clouds due to disturbances and threats. They are related to many severe conditions like hail,heavy rain,tornadoes,heavy rain etc. They have the capability of creating dangerous and severe weather conditions on the earth's atmosphere. Therefore the related phenomena with cumulonimbus clouds hail, tornadoes and lightening.
