Answer:
The sun is a star. This makes it extremely important for life on Earth. The sun provides us with energy, which brings life on our planet. It defines the seasons, the harvests, and even the sleep patterns of all living creatures on Earth.
Explanation:
Reasons for studying the Sun stretch far out into space aswell. It is our nearest star and its proximity provides heat and light to maintain life on Earth, as well as being a unique laboratory to test our theories of the evolution of other stars and the formation of galaxies.
Answer:
Yes, cloud cover is an important factor influencing the solar radiation
Explanation:
- <u>Length of the day and the angle of the sunshine </u>and place located on the sphere of the earth are also considered vital factors in the infrared radiation that reaches the ground and is transferred into space from the same processes.
- There exists a seasonal variation in the incoming and outgoing of long and shortwave energy of the sun which is related by the <u>earth rotation as a black body at the night.
</u>
- The latitude which is located close to the equator is getting most of the sun rays and have a longer amount of insolation reaching the ground.
- Thus the places located on the poles have a lower angle of incidence of rays hence there is less radiation and less amount of energy is generated due to the <u>snow has a very high albedo than the tropics</u>.
- To predict the weather analysis of clouds over the area needs to be taken care o as these influence the winds and temperature patterns. Like the formation of high and low-pressure areas over the lands.
Answer:
Explanation:
The physical environment is the part of the environment made up of both man-made and natural features. They consist of some physical factors like water, soil, e.t.c. Mountains, rivers, valleys, hills, dams, lakes all makes up the physical aspect of our environment and much more.
The physical environment can limit human activities in the following ways:
- Barriers to communication and transportation: most times roads have to be cut through longer distances in order to bypass natural features like a huge mountains, a voluminous river e.t.c. This can severely impact the communication between places and people.
- Natural disasters: The physical environment can pose serious risk to humans through disasters such as earthquake, landslide, flooding, wildfires, e.t.c.
- Drought and famine: When several elements of the physical environment combines, they can lead to little to no rainfall for plant to thrive. This is very dangerous for life on earth. Human activities are connected a lot to how rich and useful a soil can be.
- Climate changes and global warming: Human activities are greatly impacted by changes in climate and weather. If too much rainfalls, it becomes a problem to farmers and human activities as a whole will suffer. If sunshine diminishes abnormally, the earth suffers as solar radiation is very key to life on earth.
