When a sound from a source is refracted away from the surface of the Earth it gives the indication of what?
The has high humidity
When a sound from a source is refracted away from the surface of the earth it gives an indication that the air is cooler than the ground?
Ground is cooling faster than the air.
When a sound from a source is refacted away from the surface of the earth it gives an indication that?
the surface is solid, nothing to absorb sound.
What does the energy of sound become?
The energy of sound remains as energy an slowly it enters the earth' surface or it rises up in the sky and finally goes into the universe.
How position relates to gravity?
The distance between two masses is directly proportional to the gravitational force between them. For example, the further you are from Earth's surface, the weaker Earth's gravitational force is on you. Source: high school physics

Why are sounds louder at night?
i think it might be because there are fewer sounds to mask the source. normally in the daytime there is a lot of vehicular traffic that can mask many sounds.another possibility is that once the sun is not heating the air near the surface of the earth comparitively the air higher up is warmer. this has an effect of a temperature gradient where sound propagation originating from near the earth surface is refracted back down to the earth once it reaches the higher warm air. this allows the sound to travel further with less attenuation.
When a sound from a source is reflected away from the surface of the earth what situation likely exists?
The surface is warmer than the air above it, causing upward refraction.
What is the source of energy that heats earth's surface?
The sun is the source of energy that heats earth's surface. Radiation from the sun comes through the atmosphere, largely unhindered, and warms the surface of the earth.
Why are short-waves used in long distance broadcasrs?
Long-distance radio waves are particularly affected by the E and F layers of Earth's ionosphere, causing them to be refracted and reflected back to Earth at a much farther distance or range than they would travel along the Earth's surface. The Earth's surface often reflects the radio waves back up to the ionosphere, where they are again refracted and reflected back to Earth, adding another large distance to their range
What Source of most water that evaporates from the earth surface?
This source is water from oceans.
Source of heat energy that keeps the surface of the Earth warm enough support what?
Source of heat energy that keeps the surface of the Earth warm enough support LIFE
Why is a lunar eclipse called a blood moon?
During a total lunar eclipse some light is refracted through Earth's atmosphere and onto the moon's surface. Because the refracted light is red, the moon will appear red like blood.
What is the source of energy for many processes on Earth surface?
The sun
What energy source is beneath the Earth's surface?
Solar Energy.
