Every single thing on this earth in one way or other is dependent on one thing, and that is “The Sun.” It is impossible for us to survive in this beautiful earth without the sun.
The sun is far away for the earth, but the heat and light are coming from the sun prevents the earth from being an ice-coated lifeless planet. The sun helps our plant to sustain life.
Moreover, the sun controls our weather pattern. We use different meteorological instruments to determine or to get the accurate data of the weather, but all these would have gone to vain if there was no sun.
It is obvious that the sun has a great effect on the earth along with its weather. The effects most of the time are advantageous, but sometimes this sun becomes the reason of sufferings.
Without any due, let’s discuss the effect of the sun on the earth and also the weather which will give a view of how vital the sun is for the sake of our existence.
Effect of Sun on the Earth
The energy that the earth gets from the sun is significant. The sun keeps our planet warm and prevents it from being only an ice-coated rock.
In the primitive age, people used to worship the sun as they were afraid of losing the sun during the eclipse. Later on, scientists have studied and invented different solar instruments that give data as well as the information about the sun and its actions and importance in every aspect.
From the sun, we get a required amount of heat and light, and any disturbance in its regulation will have a severe effect on the earth. For this reason, people used to pray to the sun and used to sacrifice different things for the sun.
Sun has the most significant impact on the stratosphere, one of the layers of the earth’s atmosphere. This is also called the ozone layer.
This layer protects the earth from many harmful gases and chemicals coming from the sun and allows only those that are useful and beneficial to the earth. Stratosphere also reduces the ultraviolet rays to a certain extent.
This is a layer under the stratosphere where the weather occurs. The surface of the troposphere becomes hot when the lower stratosphere is heated.
When the troposphere is cold, and the surface of the planet is hot, it creates a temperature difference which leads to storms and hurricanes.
This layer surrounds the earth like a shield and protects the earth from electrolytes that are charged particles and plasma. This layer induces the electrical current in the atmosphere and the ground.
These are the particles that come from the sun at a high rate of speed and when they pass through the human and the atmosphere, they will cause genetic change in humans and can damage the electronics of the satellite.
Usually, the layers of the atmosphere save the earth from these harmful particles.
Effect of The Sun on The Weather
The sun is a massive source of energy, and it continuously emits its energy into space. Some of its energy enters the earth through the radiation.
The solar radiation that seems to be a short wavelength and of ultraviolet type can be dangerous when it crosses all the layers of the atmosphere and enters the earth’s surface.
When the solar radiation is absorbed by the earth’s surface, it begins to heat up, and the air of the earth also starts absorbing the radiation. It is said the particle that absorbs faster also emits at a quicker rate.
The air then emits the radiation in a longer wavelength in the atmosphere that warms up the surface of the earth, and for this, the surface of the earth is warmer than the air above us.
On the first day of spring, the sun lies directly over the equator and when it is over the equator, the solar radiation is received vertically.
But if you proceed through the north and south of the equator, the radiation comes at lower angles. The lower the angles, the less the energy is received which means that there is less energy to warm up the air.
This might seem that all the year the equator will face hot and in the polls, it will be cold. But all of us know that, throughout the year, the temperature is not the same.
This is because the earth rotates to its axis, thus during summer it is hot in the northern hemisphere while in the southern hemisphere it is cold as the sun angles are much lower.
We know that after every six months, the seasons change as after six months the earth changes its direction about the earth. Thus the season along with the weather varies because of the sun and the rotation of the earth.
The sun has great impact on our earth as well as other planets. Due to the sun, the earth is lively instead of a rock of ice. There is no doubt that because of the sun can see and feel the different seasons and can sense the hotness and coldness.
In fact the sun is important for our existence in this earth as well as for the life of the earth.
