Answer:
Option C:
The magma's cooling rate determines the size of crystals that are formed.
Explanation:
Once magma erupts from a volcano to the surface of the earth, it begins to cool because of the relatively cooler temperatures at the surface of the earth.
The magma usually cools down to form igneous rocks on the surface of the earth. The rate at which the magma cools down determines the size of the rock crystals that are formed.
If the magma cools slowly, there is enough time for crystal growth within the rock particles. This gives rise to larger rock crystals.
If the magma cools rapidly, there is little time for crystal growth. This leads to the presence of smaller rock crystals.
Answer:
A system in which power is divided between the national and state governments. Significance: Federalism allows people living in different states with different needs and different interests to set policies suited to the people in their state.Federalism is a system of government in which the same territory is controlled by two levels of government. Generally, an overarching national government is responsible for broader governance of larger territorial areas, while the smaller subdivisions, states, and cities govern the issues of local concern.
Answer:
Evolutionary
Explanation:
Since the early days, human has managed to learn and adjust to his environment, worked on developing and nurture the greatest feasible habits and mechanisms for survival. Survival was of the greatest priority, as prehistoric cavemen were living in a multitude of dangers, varying from infections to wild, starving animals, etc. As per the evolutionary psychology, our ancestors had psychological upsides, transferred these behavioral traits to subsequent generations, culminating in a generation that then had these adaptive behaviors phobias.
Answer:slowing of deep ocean circulation, resulting in lower oxygen levels in deep waters
Explanation:ocean circulation is like a conveyor belt which transports warm water and precipitation from the equator e the poles and cold water from the poles to the tropics . This process is crucial in maintaining global climate effectively , it helps with effective radiation control ensuring that the earth surface receives safe radiation.
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
