Because it determines temperatures, wind patterns, and air pressure
Answer:
Knowing that the temperature at sea level (0 m) is 20 ° C, we will calculate the air temperature at. The altitude of 3500m.
According to the vertical thermal gradient, the air temperature decreases by 6 ° C at 1000m alt.
1000 m .... 14 ° C (20-6 = 14)
2000 m .... 8 ° C (14-6 = 8)
3000 m ... 2 ° C (8-6 = 2)
3500 m .... - 1 ° C (2-3 = -1

Answer:
Explanation:
Measuring the amount of deu terium in the universe allows us to set a limit on the density of ordinary matter of universe. Density of the universe is about 9×10-27 kg m-3, because of the way in which deu terium was created in the Big B ang, an exact measurement of the amount of deuterium would allow scientists to set limits on the models of the great explosion.
Answer:
Option (3)
Explanation:
In a region where the temperature is high, the air gets heated up. As a result of which the air becomes warm and less dense and rises up into the atmosphere forming a low pressure zone. This air when rises up, it experiences a cooler temperature and gets cooled. This cooling allows the air mass to become dense and starts condensing. It then precipitates in the form of rainfall. This motion of air particles in the atmosphere forms a convection, that is similar to the one that forms in the mantle layer of the earth.
Thus, the warm air transfers heat forming convections.
Hence, the correct answer is option (3).
Answer:
Oceans have landforms because of volcanic activity.
Explanation:
Oceans are dominated by water, but they are not exclusively covered with water on their surface, but there are also a lot of landforms. The landforms are small in the percentage of the total area, but nevertheless, they can be found in varying sizes and shapes. The reason why oceans have landforms is the volcanic activity.
When it comes to landforms that are located near the edges of the oceans, they tend to be created because of subduction zones. Here we have a rise of magma from the mantle and the creation of volcanic island arcs, like in the case of the Japanese islands. When it comes to landforms that are found deep into the ocean and far away from plate boundaries, the cause is hot spot volcanism. This volcanism occurs above places where there is higher than usual activity in the mantle, and it is such a powerful activity that it breaks through the crust and manifests itself on the surface. An example of this type of landforms is the Hawaii Islands.
