Explanation:
Magma convection is the primary driving mechanism by which geothermal energy is brought to the earth.
Geothermal energy is energy from deep within earth has been brought close to crustal levels.
They are usually sourced from areas in which a body of magma is appreciably close to the surface or where the mantle is close up.
- Mantle convection is movement of magma within the region of the earth's mantle.
- In this process, hot magma rises up close to the surface and cold ones sinks further deep into the mantle.
- As hot magma rises in the mantle, it is brought close to the surface and crustal levels.
- Where the crust is thin, the heat from the ensuing magma can be felt more close up
- Cracks in the overlying lithosphere can bring these magma up ensuring a continuous supply of this hot mantle materials.

Answer:
1+2=2+1 is the answer for the question
Answer:
C
Explanation:
It is formed as a result of a reaction between two non-metals
Realize that pH + pOH = 14
so, 9 + pOH = 14 -> pOH = 5
pOH = -log[OH-]
5 = -log[OH-]
plug it into a calculator and you get 1.0 x 10^-5
alternatively, use [OH-] = 10^-pOH to get the same answer
[OH-] = 1.0 x 10^-5
Lets take 100 g of this compound,
so it is going to be 2.00 g H, 32.7 g S and 65.3 g O.
2.00 g H *1 mol H/1.01 g H ≈ 1.98 mol H
32.7 g S *1 mol S/ 32.1 g S ≈ 1.02 mol S
65.3 g O * 1 mol O/16.0 g O ≈ 4.08 mol O
1.98 mol H : 1.02 mol S : 4.08 mol O = 2 mol H : 1 mol S : 4 mol O
Empirical formula
H2SO4
