Plate tectonics are important to geoloigists because they explain how the continents make up the earths crust.
Answer:
It would seem that the answer in the question is correct
Explanation:
falls in the form of ice or snow is already unusable because of acid rain evaporates back into the atmosphere is taken up by plants or other organisms either runs off to form rivers or filters down into underground aquifers

Set this up as
10 = 40 (1/2)t/28
and solve for t in years.
10/40 = (1/2)t/28
log(0.25) = (t/28) log(0.5)
t = 28 log(0.25) / log(0.5) years = 56 years
Test the answer:
56 years = 2(28 years) = 2 half-lives, so the remaining amount should be 1/2 of 1/2 of the initial amount, i.e. 1/4 of the initial amount, and 10 mg = 1/4 of 40 mg.
Sand is suspended in the water of seas and oceans by the action of waves and currents, and it is then deposited by the same wave action and storm surges at high tides or high water levels. Over time, the sand accumulates to create beaches, which are actually enormous sandbars.
<h3>Where will sand deposition cause the beach to spread for the first time?</h3>
around the area where the waves break. The sediments rub up against one another as a result of the moving water.
<h3>What is the primary reason for the incoming waves?</h3>
The most frequent waves are surface waves, which are brought on by wind moving over the air-water interface and causing a disturbance that gradually increases as the wind blows and the wave crest rises. The waves you see at the beach often are surface waves, which are continually present around the world.

When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Old, dense crust tends to be subduction back into the earth.
