The Moon is currently geologically inactive. At present, what is responsible for breaking up surface rocks on the Moon?a. impacts
b. volcanism
c. water erosion
d. energy from the Sun

Answers

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.

Scientists are able to determine the relative age of rocks in specific years. TRUE or FALSE.

Answers

Answer:

FALSE

Explanation:

  • As it's difficult to determine the absolute age of the rocks the scientist measures the relative ages of rocks as the ages are a comparative study of the risks by the scientists and the geologist as they map the earth for the various sources.  
  • There findings of the carbon signatures of the rocks and hence tend to give the presence of older and younger rocks composition on earth like the sedimentary rocks are arranged in the strata and layered information hence os easy to point out the exact or specific year of the rock.
False. They would be able to guess the general century by whats in the rock, but not specific years.
