Answer:
a. impacts
Explanation:
The moon is so bombarded by space rocks that its surface changes completely every 81,000 years, according to a study released from NASA data.
These jolts - which affect the two inches of the almost completely detached moon dust - occur almost 100 times more often than previously thought, scientists said.
The study also estimates that asteroids and comets that collide with Earth's natural satellite generate, on average, 180 new craters at least 10 meters in diameter each year.
The findings, published in the British science journal Nature, are from before-and-after photos taken by NASA's Lunar Reconnaissance Orbiter, which has been mapping the moon since 2009.
By comparing images of the same area at regular intervals, a team of scientists led by Emerson Speyerer of Arizona State University in Tempe were able to record the number of new craters and extrapolate this figure to the entire lunar surface.
"We detected 222 new impact craters and found 33% more craters at least 10 meters in diameter" than predicted in previous models, the scientists concluded.
The researchers also discovered thousands of subtle surface disturbances, which they described as "scars" of minor and minor impacts that, after thousands of years, shook the moon's surface layer without producing craters.
Answer:
Disapear in a great Earthquake
Explanation:
The snow at the top of the Himalayas seems eternal and dormant, but it is not: it grows at an annual rate of four millimeters due to plate tectonic pressure, which increases the fear of an earthquake in Nepal. The phenomenon escapes the human eye, but dates back millions of years. The Indian plate slowly slips under the eurasian plate, and this pressure gradually lifts the highest mountains on earth.
The mountain range grows 4 millimeters upward each year, because the Indian plate continues to slide between 2 and 2.5 centimeters annually under the eurasia. On the surface, the arm wrestling between the two plates has potentially terrifying consequences in Nepal, where experts predict a “big earthquake” and the population reacts in terror to any news of earthquakes elsewhere.
Volcanoes in subduction zones form on the overriding plate as the subducting plate sinks beneath it. The subduction process creates deep ocean trenches where magma rises to the surface, forming volcanic arcs and mountain ranges.
In subduction zones, volcanoes typically form on the overriding plate as the subducting plate sinks beneath it.
When the subducting plate bends and plunges into the mantle, it creates a deep ocean trench. As the oceanic crust subducts, it begins to melt due to high temperatures and pressure. The melted rock, or magma, is less dense than the surrounding mantle, causing it to rise to the surface and form volcanic arcs or mountain ranges.
Examples of volcanic arcs formed in subduction zones include the Andes in South America and the Cascades in North America.

Most of Earth's lakes formed after the last Ice Age. When the glaciers melted, the water drained into these basins, and became lakes.
Hence, the correct answer is melting glaciers.
B: The Coral Sea
C:The Torres Strait is a body of water which lies between Australia and the Melanesian island of New Guinea.
D: The Tasman Sea
E: The Torres Strait
Answer:
The correct answer is E. The body of water that lies between Australia and Papua New Guinea is the Torres Strait.
Explanation:
Torres Strait is a strait between the Cape York Peninsula in the Australian state of Queensland and Papua New Guinea. The strait is about 150 km wide and connects the Coral Sea in the east with the Arafura Sea in the west.
The Torres Strait was discovered in 1606 by Spaniard Luis Vaez de Torres, who followed the south coast of New Guinea from east to west. It would, however, take until James Cook in 1770 until another person sailed it down.
