Answer:
The given statement about the air parcel is True
Explanation:
It can be explained as atmospheric pressure on air parcel is higher due to which it contracts when it is close to earth but if the temperature inside the parcel is more than that of the surrounding then due to low density it will rise upward and as the parcel gains height the air pressure exerted by the surrounding on the parcel reduces due to increase in height of the parcel from the earth and hence the air parcel expands. The entire process happens with heat being constant (adiabatic) i.e., amount of heat transferred in the expansion remains same.
Now, the same amount of heat is scattered on the expanded area leading the parcel to cool as it ascends.
The main difference between geography and geology
is that geography is mostly dealing with the physical overall shapes of
the land. Geology is a science that is interested in how the land got
into the shape it did.
Geology is mostly about what the ground is
made up of from a natural perspective. What kind of rocks it contains
and how those rocks or layers of rocks got there.
Geography is
mostly dealing with mapping the extent of landforms, how far rivers are,
how long mountain ranges are, how long the coast line is. This is often
from the perspective of people or culture.
Question
Mid-ocean ridges are steeper and less broad than rises because:
Group of answer choices
A) the rocks of the mid-ocean ridges are composed of more dense mineral than the rises.
B) the rocks of the mid-ocean ridges are composed of less dense mineral than the rises.
C) The seafloor spreading rate of ridges are faster than rises causing the oceanic crust to subside closer to the ridge axis.
D) The seafloor spreading rate of ridges are slower than rises causing the oceanic crust to subside closer to the ridge axis.
E) Every ridge is composed of continental crust.
Answer:
The correct answer is D.
Explanation:
In volcanic regions, as the molten magma flows out onto the seafloor creating new beds, the faster it flows, the less steep the mid-ocean ridge is. If however, it is slow-flowing, then oceanic lithosphere formed cool closer to the ridge axis thus making it very steep.
Cheers!
