Question

I. Complete the following :
1. Due to the
nature of the earths axis, there is an unequal distribution of
heat or solar energy on the surface of the earth. The amount of heat a place gets
depends on the
of the sun's rays at that point. Based on the amount of
received, each
is divided into
temperature zones.

Answer 1

Solar radiation, often called the solar resource or just sunlight, is a general term for the electromagnetic radiation emitted by the sun. Solar radiation can be captured and turned into useful forms of energy, such as heat and electricity, using a variety of technologies. However, the technical feasibility and economical operation of these technologies at a specific location depends on the available solar resource.

BASIC PRINCIPLES

Every location on Earth receives sunlight at least part of the year. The amount of solar radiation that reaches any one spot on the Earth's surface varies according to:

Geographic location

Time of day

Season

Local landscape

Local weather.

Because the Earth is round, the sun strikes the surface at different angles, ranging from 0° (just above the horizon) to 90° (directly overhead). When the sun's rays are vertical, the Earth's surface gets all the energy possible.
