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:
•The existence of water at the Earth’s surface—neither too much nor too little—that is in liquid form.
•Proximity to the sun—neither too much heat nor too little.
•System of plate tectonics that enables the carbon-silicate cycle regulating temperature.
•The right size—large enough to hang on to its atmosphere, but not so large to hold on to too much atmosphere and consequently too much heat.
•Its protection by “big brother Jupiter,” whose gravity helps divert and vacuum up incoming debris and keep Earth safe.
•The moon’s stabilizing effect on our planetary rotation, which prevents the poles from shifting unexpectedly.

Echo sounding
Explanation:
Harry Hess discovered the Mid-Atlantic spreading ridge by using echo sounding techniques.
- Hess was a professor of Geology at Princeton University.
- After the second world war, series of equipment used were deployed for scientific use.
- The echo sounding was one of such devices that was adopted in mapping the sea floor.
- It works by sending an echo to the ocean floor and determining the height to the base by their reflection.
- From his works, he observed and noticed the mid-oceanic ridge.
- This led to the formulation of the theory of sea floor spreading.
