Answer:
It's the 4th, as third is modified by the man.
Explanation:
- The Third atmosphere was a rearrangement of the plate tectonics and the evolution of atmosphere by the transferring of it to the oceanic basins. As the amount of oxygen in the atmosphere used to be more than 30% around 280 million years ago than the present.
- Rapid development of land plants and animals was caused due to this atmosphere and hence this atmosphere is now less than 21% and due to his influence or modification of man with his technological tools and techniques.
- The atmosphere is rapidly shrinking due to the greenhouse effect and global warming that is leading to the fifth atmosphere that may be like that of mars as devoid of gases and barren and dry with oceans running under the crust.
Answer:
<u>To bring awareness about the underwater volcanoes</u>.
Explanation:
- The eruption of the volcanoes, and the occurrence of the earthquakes on the planet and the spilling of the lavas, and the smoke-filled air hat comes to from the vent of the large craters.
- <u>As most people think that the volcanoes are present on the land areas only does not mean that they are confined to the above surface of earth they are also characterized by the deep hydrothermal vent and the most pope thus are surprised to know about them as they don't know that they are the primary place for the origin of the first life forms n the earth in the single-celled bacteria.
</u>
- They generally spill out the lavas and the magmas and this is called sth submarine volcanoes and ends to occur along the mid-ocean ridges. And are known to give out an estimated 75% of the volume of the lavas on earth.
- T<u>hey are also known as the seamounts that are created from the extinct volcanoes that occur in 1000 to 4000 meters depth of the seafloor.</u>
Earthshine is even more faint because the moon's "albedo" (a specific kind of reflectivity) is less than Earth's. Even though this dim light is only a reflection it can still illuminate some features of the moon. Earthshine can be best seen during the crescent phases (the 1-5 day period before or after a New Moon).
Twilight zone because the twilight zone is the deepest part of the ocean
