Radio and tv signals are reflected back to earth in witch layer?
Radio and TV signals are reflected back to Earth in the ionosphere, specifically in the F layer. This layer is located approximately 150-500 kilometers above the Earth's surface and is characterized by its ability to reflect high-frequency radio waves.
What term is used for the continually frozen layer of soil underneath Earth's surface in high latitudes?
Permafrost is used for the continually frozen layer of soil underneath Earth's surface in high latitudes.
Why does plain cement concrete is used?
As far as my knowledge is concerned, PCC is used for 2 purposes 1. It is used as a protective layer for the RCC above so that water from the RCC is not absorbed by the earth below. 2. Provides a base for the concrete and also helps workers to set out the structure above in a easier way
What layer of the atmosphere is used for radio communication?
The layer of the atmosphere used for radio communication is the ionosphere. This region, located approximately 30 to 1,000 miles above the Earth's surface, contains ionized particles that can reflect radio waves back to the Earth, allowing for long-distance communication. The ionosphere's properties vary with solar activity and time of day, influencing the effectiveness of radio signals.
What are three protective devices used to protect typical power circuits?
Overload protection Short circuit protection Earth leakage protection
How can you use relative dating in a stentence?
Relative dating can be used to determine the sequence of events in geological history by comparing the ages of rock layers and their fossils. For example, if sedimentary rock layer A is found above layer B, we can infer that layer A is younger than layer B. This technique helps establish a timeline of Earth's history without providing exact ages.
What level is marked by the base of a cloud layer?
The base of a cloud layer is typically used to determine the height of the cloud layer. It is measured in feet above sea level and is used to indicate the altitude level at which the cloud layer begins.
How does scientist were able to arrive at the distinct layer of the earth?
They used earthquake waves.
What is Ino-sphere layer?
There is no widely recognized term or concept known as the "Ino-sphere layer." It is possible that it may be a made-up or specific term used within a certain context or field. If you can provide more information or context, I may be able to assist you better.
What protects us from most of the electromagnetic radiation from the sun?
The ozone layer protects the earth from most of the electromagnetic radiation from the sun. This is usually not enough protection on sunny days so a sun screen should be used when people are active outside.
What is the earth layer?
In 1942 the geophysicist Keith Bullen published a paper describing the earth's internal layering in which he used letters to designate various layers from the surface to the core. In this scheme, the earth's lower mantle was known as the D layer.
How have chlorofluocarbons harmed the environment?
For years people thought chlorofluorocarbons were harmless. Then someone discovered they destroyed the ozone in the ozone layer. The ozone layer stops the most dangerous of the sun's rays. Those rays cause cancer when they strike an individual. The continued use of chlorofluorocarbons would wipe out life on earth that lives above the ground or above sea level from cancer. As a result, it became illegal to make machinery that used them. When machines that used them had to be repaired, a different refrigerant had to be used.
