Can water molecules evaporate at the surface or below the surface?
Water molecules can evaporate from the surface of water, where they gain enough energy to overcome surface tension and escape into the air. Below the surface, water molecules can also evaporate through a process known as sublimation, where molecules transition directly from a solid to a gas, although this is less common.
Ground water exists below the surface of the earth?
Yes, groundwater is the water found beneath the Earth's surface in the pores and spaces of soil, sand, and rock formations. It is a valuable natural resource that is often used for drinking water, agriculture, and industrial purposes.
Why the surface layer of water in the poles is colder than the layer just below it yet the colder layer floats on top?
The surface layer of water in the poles is colder due to exposure to cold air and ice. This layer becomes denser as it cools, causing it to sink below the less dense, warmer water below. This creates a stable situation where the colder layer remains at the surface.
Is the force of the water on the piers the same at the water surface as it is 30m below the surface?
No, the force of water on the piers is greater at 30m below the surface compared to the water surface due to the increased pressure at greater depths. The pressure in a fluid increases with depth, so the force exerted by the water on the piers will be higher at 30m below the surface compared to the water surface.
What is water found below the surface called?
ground water
