What is ground refraction?
Because the rate at which sound propagates changes with temperature, it is possible for sound to be refracted by changes in the air temperature at low altitudes. Sounds may be refracted toward or away from a listener. This can create what is known as a "shadow zone" a short distance from the sound source, where the sound will be diminished or not heard at all.i think it is that the air is cooler than the ground
You are able to hear sounds from farther away on a cool night because sound waves are refracted toward warmer air near the ground?
yes
How does friction between the ground and the molecules in the air affect winds near the earths surface?
Wind at the surface is slower than the "winds aloft" The biggest effect is within a few inches of the ground.

How does ground motion produced by a p wave compare to the ground motion produced by surface waves?
The underground motion of a P-wave usually effects the us less than ones near or on the surface.
Why the amount of rock at the earth surface stays constant?
because it is cooler above ground
What happens if the ground is cooler than the air?
When the ground is cooler than the air you get fog.

Why might a major volcano eruption lead to cooler temperatures over a large area around the area?
Because when the volcano erupts it lets all the hot volcanic acid and lava out of the ground making the earth's surface cooler.
Why do squirrels lay flat out?
Squirrels lie flat in hot weather to cool off. In this position, they increase the amount of their body's surface area that is in contact with the ground. If they find the right spot, the ground temperature will be cooler than the surrounding air, allowing a lot of their body's superficial blood vessels to be closer to the cooler ground. This phenomenon actually has a name: it's called "Splooting"
Storing food in old days?
Ice chest. Ice man delivered fresh ice every couple of days In holes in the ground - cooler than above surface
Would most likely occur when an air mass is resting on cooler ground?
Fog would most likely occur when an air mass is resting on cooler ground. This is because the ground cannot absorb the moisture.
How do you use heat from the ground?
Heat from the ground can be used to stabilize the temperature of a house, keeping it warmer in winter and cooler in summer.Heat from the ground can also be used on a larger scale by pumping water down deep enough into hot rocks where it will become hot enough to generate electricity back on the surface.
How does a ground fog come about?
Water vapor in the air condenses when the ground cools at night. the cooler ground (often due to radiation into space when it is clear) cools the air near the ground. This cooler air cannot hold as much moisture as warm air and the moisture condenses as fog.
Where do snakes like to live in the desert?
in the ground because it is cooler the out side
Is a river surface or ground water?
Ground water
When does surface water become ground water?
When the ground water flow out of the earth surface as a form of spring.
