The correct answer that would best complete the given statement above would be option D. LAHAR. The mixture of water and rubble that flows from the slope of a volcano is a LAHAR. It is a fast moving flow. Hope this answers your question.
Answer: The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point. The density of seawater is increased by increasing pressure.
The correct answer is - The water was heated by magma or hot rocks.
The hot water that is erupting from the vents comes from the geologic activity inside the Earth. The water that is deeper into the ground, where there's geologic activities around the area, gets heated by the magma or hot rocks, was results in increasing the pressure, thus the water is shoot out in the air, looking like the vents are erupting.
Most of the vents like this can be found in areas that are close to a volcano, or are connected with a volcano through underground channels.
water often erodes without being in a channel. rainwater that begins to run off during a rainstorm, often flows as thin, broad sheets before forming rills and streams. For ex: wen it rains over an area the rainwater accumulates until it begins moving down a slope as a sheet. Water can also flow as sheets if it breaks out of its channel. floodwaters spilling out of a river can flow as sheets over the surrounding flatland's. streams flowing out of mountains fan out and many flow as sheets away from the foot of the mountain. sheet erosion occurs when water that is flowing as sheets picks up and carries away sediments.
Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. currents regulate global climate, helping to counteract the uneven distribution of solar radiation reacting eat the surface
warmer water currents are near the surface
surface currents are caused by wind and density differences in the water
