In the hydrologic cycle, water from the ocean into the atmosphere where it can and change back into tiny water droplets.

In the hydrologic cycle, water from the ocean:

evaporate, it means that the water "transforms" into vapor, so goes in the atmosphere and form clouds.

into the atmosphere where it can:

Condense, it means that the vapor in the atmosphere cold down his temperature and transform in liquid water again.

So evaporation is the process where some liquid changes of phase to a gas state. (here water to vapor of water)

and Condensation is the process where a gas changes of phase to a liquid state. (here vapor of water to water)

c)as speed changes, wavelength and frequency change.

everything changes!

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
