There are three types of fossil fuels: Oil, coal and gas.
Let's look into their formation one by one:
Oil: Dead plankton such as microorganisms and plants was buried under the sea million years ago, it accumulate over time to become oil, also known as petroleum,
Coal: Plants were dead and broken down by bacteria over time, carbon dioxide and methane were produced. After million years, the dead flora accumulated to become peat and undergone compaction, becoming coal.
Gas: This is formed along oil, and again produced by dead organisms. It is mostly formed during decomposition, and mostly made up of methane.

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

Answer:
b. the porous and permeable, saturated cone of depression in an aquitard.
Explanation:
An aquifer is an underground layer of water, surrounded by a porous, and saturated layer of water bearing rock. The aquifer is lined by a layer of bed of low permeability along its length. This layer is called an aquitard, and it usually forms a depression.
