answer the following given above
Answers
Answer:
1. A lithosphere is the rigid, outermost shell of a terrestrial-type planet or natural satellite
2. the gaseous envelope of a celestial body (such as a planet)
3. a photosynthesis is a process in which green plants turn carbon dioxide and water into food using energy from sunlight
4. The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.
5.The biosphere is a narrow zone of the earth where land, water, air interact with each other to support life. It is in this zone that life exists
6.There are three basic conditions for the existence of life on a planet
1. Water on the planet should be in abundance.
2. The planet’s atmosphere must be free from harmful gases.
3. The temperature on the planet must be tolerable to the living beings.
It is found from the observations that the planet which is fulfilling all the above three conditions is our Earth. Not even a single planet except earth has these suitable conditions. So, possibility of life on other planets if almost Zero
7.The earth is so for the only planet which consists of life- system. It is due to its ideal average temperature of 17°C to support the life and provide with atmosphere and hydrosphere to impart air and water essential for life.
8.The earth is largely (71 percent of the surface of the earth) covered by water. ... As illumination enters the water, the water consumes white light and reflects just blue light, lights of all colors. The earth from space, thus, looks blue.
Answer:
1. the rigid outer part of the earth consisting of the crust and the upper mantle.
2. atmosphere is a layer or a set of layer of gases surrounding the planets and other celestials bodies which is held in place by the gravity of that body.
3. photosynthesis is the process where the green plants and other organisms prepare their own food by using sunlight which synthesis the nutrients from carbon dioxide and water.
4. It is a natural effect that warms the earth' surface.
5. Biosphere is the region of the surface and atmosphere of the earth which is occupied by living beings.
6. The condition necessary for life in earth are:
(a) Moderate Temp
(b) air
(c) water
(d) sunlight
(e) oxygen and carbon dioxide
(f) land
7. (a) The earth is the only planet which consists life
(b) It also contains Water and atmosphere and proper sunlight and temperature
8. As the earth consist of 71% of water it gives the color as blue and therefore from the space the earth seems to be blue in colour.
