The statement "It is made possible by heat and pressure." is true about all convection currents.
To select the best answer, we need to carefully analyze each statement and determine its accuracy.
The first statement, "It causes earthquakes," is not true about all convection currents. Convection currents are responsible for various geological phenomena, but earthquakes specifically occur as a result of tectonic plate movements, not solely due to convection currents. Therefore, we can eliminate this option.
The second statement, "It happens in all layers of the Earth," is true about all convection currents. Convection currents occur in different layers of the Earth, including the mantle and the outer core. This option is a correct statement about convection currents.
The third statement, "It results in the formation of valleys and hills," is not true about all convection currents. While convection currents can cause various landforms, such as mid-ocean ridges and volcanic mountains, valleys and hills are not directly formed by convection currents. This option can be eliminated.
The fourth statement, "It is made possible by heat and pressure," is also true about all convection currents. Convection currents occur due to the transfer of heat energy within a fluid, which can be caused by a combination of heat and pressure differentials. Therefore, this option correctly describes the underlying factors that facilitate convection currents.
Upon evaluating all the statements, the best answer is the second statement: "It happens in all layers of the Earth" and the fourth statement: "It is made possible by heat and pressure."
