Answer:
in cold sector the earth are little bit far than sun on the basis of warm sector .
another thing is also that due to the near of equator too
Answer:
ooh am sorry your question is incomplete
One of the characteristics of light is that it behaves like a wave. As a result, light can be defined by its wavelength and frequency. The frequency is how fast the wave vibrates or goes up and down. The wavelength is the distance between two peaks of the wave. Frequency and wavelength are inversely related, meaning that a low frequency wave has a long wavelength and vice versa.
When light hits a surface, some of it is absorbed and some of it is reflected. The light that is reflected is the colour of the object in that light. For example, a blue object absorbs all the colours of the spectrum except blue: it reflects blue light. Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. When white light shines through a prism or through water vapor like this rainbow, the white light is broken apart into the colors of the visible light spectrum.
Cones in our eyes are receivers for these tiny visible light waves. The Sun is a natural source for visible light waves and our eyes see the reflection of this sunlight off the objects around us.
The color of an object that we see is the color of light reflected. All other colors are absorbed.
Light bulbs are another source of visible light waves.
Hope this helps :)
Answer:
Study changes in an ecosystem using satellite imagery.
Explanation:
A geographic information system (GIS) is a system that is designed to gather, manage and analyze data. These systems are used by geographers, and it allows them to integrate many different types of data, particularly spatial data. Therefore, this system can be used in the development of maps, 3D scenes, and visualizations. Therefore, it would be a useful tool to have when studying changes in an ecosystem using satellite imagery.
