Answer:
The imaginary line that separates light from the darkness and day from the night is known as the circle of illumination. Earth's axis refers to an imaginary line going through the centre of the earth from top to bottom. The circle of illumination cuts all latitudes into half on the spring and autumnal equinoxes.
Solar panels are expensive, they are kept this way by the companies.
The price ranges around $10.000 - $15.000 for an installation. It takes years to get this investment back and in the meantime the batteries need to be changed and power converter need to be maintenance, etc.
your answer is 4. sufficient sunlight reaches only a few locations
The combination of the weathering and erosion of the stream bank and the cutting into the bedrock from the velocity of the stream combine to make a "stream valley".
<h3>
What is stream valley?</h3>
A stream valley is an earthen dip where water is present at its lowest point. These valleys are the result of erosion, which is the transfer of decomposed rock or soil from one location to another.
The formation of stream valley is given below-
- The typically V-shaped stream valley is changed to a U-shaped valley because the U-shape offers the flowing glacier the least amount of frictional resistance.
- Because a glacier's cross section and viscosity are substantially greater than those of a river, its route has fewer and wider bends.
