Answer:
True
Explanation:
20% of water precipitation
Answer:
1- Option (D)
2- Option (C)
Explanation:
The rocks of oceanic crust are created by spending a huge amount of time in a water-rich environment. During the subduction process, the plates at greater depth are comprised of rocks that contain water in them. As this water reaches the mantle, the conditions of pressure and temperature forces these hydrated rocks to remove the water from them. This water then mixes up with the mantle and thereby reduces the melting point of the mantle rocks. This results in the formation of magma. These magma being lighter eventually rises upward that eventually leads to the formation of the volcanoes. This process of melting is known as the hydration-induced melting.
Thus, the hydration-induced melting process is responsible for the formation of volcanoes on the overriding plates.
Hence, the correct answers are mentioned above.

Answer:
Formation of Traps in rocks
Explanation:
The geological features that cause oil and Natural gas to be trapped in the rock is the formation of TRAPS and these traps are divided mainly into two types : structural traps and stratigraphic trap. but the most common and important kinds of traps are mainly structural traps because they are found in almost all the rocks where oil and gas is discovered.
The structural traps are : Anticlinal traps,and fault traps. while stratigraphic trap is : Salt dome trap
