Answer:
Human activity - Produces greenhouse gasses.
Greenhouse gasses - Cause atmosphere to trap more heat.
Sun's output - Can vary.
Ice age - Peaked 20,000 years ago.
Explanation:
Human activity includes the usage of fossil fuels on a very large scale, and by using them we release huge amounts of greenhouse gasses into the atmosphere.
The greenhouse gasses have the ability to trap the heat that is reflected from the surface of the planet, thus keeping more of it in the atmosphere and causing global temperature rise.
The sun is technically a star, thus an object that produces energy and light, and like every star, it has variations in its activity in accordance with the processes going on on it.
There have been numerous ice ages through the geological past, and the last one of them ended only around 10,000 years ago, with its peak being just 20,000 years ago.
They pollinate the place they occur.
Tornado, Hurricane, Tsunami, etc
Answer:
The intermediate magma has a heterogeneous structure, since it has a part of Silice, approximately 50-60% to be more exact.
When it turns into lava, it produces rocks like the Andesite and, in the opposite case of its crystallization, it forms rocks like the Diorite.
A comparison of felsic magma is much more viscous.
It is important to clarify that this magma is a type of primary magma, that is to say that they are magmas formed from the fusion of the rocks of the mantle or the crust.
Explanation:
The fusion of these rocks are what would give rise to the intermediate magma, this intermediate magma is a primary magma, like the mafic and felsic.
The primary magmas unlike the derived magmas is the origin or the reason for how they are formed, which is what we write above, derived magmas usually form differently since they are the product of the evolution or changes that magmas undergo primary
