What else can I help you with?
When a sound of source is refracted away from the surface of the earth it gives an indication that the?
sound speed is increasing with height above the ground. This refraction occurs due to a decrease in temperature with increasing altitude in the atmosphere, causing the sound waves to bend away from the surface of the Earth.
Does sound tend to bend upward or downard when it travels faster near the ground than higher?
Sound tends to bend upward when it travels faster near the ground than higher up, which is known as a temperature inversion. This occurs because sound waves are refracted towards the cooler, denser air near the ground.
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
Do rainbows touch the ground, or do they only appear to be reaching down from the sky?
Rainbows do not touch the ground. They appear to be reaching down from the sky due to the way light is refracted and reflected in raindrops.
What is radiation inversion?
It develops during the night when the ground cools by giving off long wave radiation. The air near the ground is cooled by contact with the ground, and this layer eventually gets cooler than the air higher up. The inversion layer is enhanced by the presence of a large high pressure above, which usually is dry and has only light winds(so there is not much horizontal or vertical mixing).

Would most likely occur when an air mass is resting on cooler ground?
If an air mass is resting on cooler ground, it can lead to the air mass becoming cooler as it picks up the temperature of the ground through conduction. This may result in the formation of fog or low-level clouds due to the cooling of the air near the surface. Additionally, there could be a stable atmospheric condition with little vertical mixing, leading to the trapping of pollutants near the surface.
Is it warmer or cooler on a clear night?
It is generally cooler on a clear night because there are fewer clouds to trap heat near the Earth's surface. Without cloud cover, heat from the ground is able to radiate back into space, leading to cooler temperatures.
What happens if the ground is cooler than the air?
When the ground is cooler than the air you get fog.
Does sound tend to bend upward or downard when it travels faster near the ground than higher?
Sound tends to bend upward when it travels faster near the ground than higher up, which is known as a temperature inversion. This occurs because sound waves are refracted towards the cooler, denser air near the ground.
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.
The air just above the ground is heated by what from the ground?
The air just above the ground is typically heated by conduction, as the ground absorbs heat from the sun and transfers it to the air molecules in direct contact with the ground surface. This process creates warm air near the surface, which then rises due to its lower density compared to the surrounding cooler air.
What causes a rainbow to appear on the ground?
A rainbow appears on the ground when sunlight is refracted and reflected by water droplets in the air, creating a spectrum of colors.

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"
What is the ground temperature?
The ground temperature can vary depending on location, depth, and time of year. In general, the ground temperature tends to be cooler at deeper depths due to the insulating properties of the soil. The average ground temperature at the surface ranges from around 50 to 60 degrees Fahrenheit.
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
