Three seismic stations are needed to determine the location of an earthquake's epicenter.
Answer:
•The existence of water at the Earth’s surface—neither too much nor too little—that is in liquid form.
•Proximity to the sun—neither too much heat nor too little.
•System of plate tectonics that enables the carbon-silicate cycle regulating temperature.
•The right size—large enough to hang on to its atmosphere, but not so large to hold on to too much atmosphere and consequently too much heat.
•Its protection by “big brother Jupiter,” whose gravity helps divert and vacuum up incoming debris and keep Earth safe.
•The moon’s stabilizing effect on our planetary rotation, which prevents the poles from shifting unexpectedly.

Answer:
The type of plate boundary between the African plate and the Arabian plate is a transform boundary.
Explanation:
A is not correct because these two plates don't move away from each other in opposite directions.
B is correct because these two plates are sliding past each other, forming a fault in the process, and basically creating a typical transform plate boundary.
C is not correct because both of these plates are continental plates, one major one, and the other minor one.
D is not correct because none of the two plates is an oceanic plate.
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.
