The answer is D. There are different types of aquifers (such as the unconfined and confined aquifers), however, they are all made up of permeable rock that holds underground water. The aquifer could be sandwiched between impermeable rocks called aquitard that restrict the movement of the water in the aquifer. This type is called a confined aquifer.
Answer:
geomagnetic field.
Explanation:
The earth magnetic field can be likened to a bar magnet with a North and South pole. It originates from the movement of molten iron and nickel in the outer core.
At every point in time, the magnetic field orientation can change. We must note that the magnetic north lies close to that of geographic north axis of the earth.
Around the mid-oceanic ridges, new materials are brought to the surface. These new materials can contain magnetic minerals such as haematite which are capable of being magnetized as a result of the prevalent magnetic field of the earth. As different materials are brought up, the magnetic minerals preserves the details of the magnetic field at that point in time. Using this information can know the orientation of the magnetic field at any point in time if the magnetic history chart of the earth is constructed. Oceanic ridges becomes older as they move away from the divergent margins.
Organism x existed for a short period of time would be my answer, it seems a lot better than the other answers
Answer: Antarctica.
Explanation: We know that every six months, there will be sunlight. And after that, there will be night. Judging by the month right now. It's the 7th month. This means there will be no sunlight for the next six months in Antarctica. (If you get this wrong, I'm sorry.)
