PLEASE HELP What role does energy play in the formation of sedimentary rock?
A.
Rain cools sand, mud, and pebbles into hard layers that solidify using energy from the Sun.
B.
The heat from the Sun melts sand, mud, and pebbles which then cool and solidify into a rock that can be broken down again through erosion.
C.
Energy from the Sun creates the cycle of rain and wind that causes erosion to produce sedimentation.
D.
Rain provides the energy needed to bring sand, mud, and pebbles to one location where energy from the Sun changes them to rock.

Explain how the density of ocean water is affected by temperature and how this results in major ocean currents distributing heat away from the equator toward the poles?

Look at the data above. provide an explanation for europe’s projected population decrease by the year 2050. (i'm doing this for future kids) the answer is : the percentage of people over the age of 65 and under the age of 15 in europe is currently the same at 16% each. therefore, the majority of the population is between the ages of 16 and 64. in forty years from now, in 2050, a greater percentage of the population will be over the age of 65. europe also has a relatively long life expectancy of 75 years. this, combined with a low birth rate means that by 2050 europe’s population will actually be less than it is today.
