Answer:
The rocks at the bottom of the ocean are younger than the rocks on the continent. This can be pessible due to the process called Continental Drift.
Explanation:
For a long time the human being wondered what would be the age relationship between the rocks at the bottom of the ocean and the rocks of the continent. Which rocks were younger or older? The scientific advance that humanity achieved during the second world war allowed this question to be answered, as it was during this period that "sonar" was created, a device that is able to reveal the ocean floor
From the creation of this device, and other equipment, scientists were able to study the underwater mountains known as oceanic dorsals. During these studies, scientists were able to create methods of donating rocks and were able to conclude that the closer to the oceanic mountains the rocks were, the younger they were. On the other hand, the closer to the continent, the rocks were, the older they were. They will conclude that this must have been influenced by the phenomenon called continental drift, which refers to the movement of the masses of the planet over a period of time.
Answer:Fixation - Fixation is the first step in the process of making nitrogen usable by plants. Here bacteria change nitrogen into ammonium. Nitrification - This is the process by which ammonium gets changed into nitrates by bacteria. Nitrates are what the plants can then absorb

Explanation:
Using a few inexpensive, energy efficient measures can reduce your energy bill and, at the same time, reduce air pollution. Heating and cooling systems use more energy than any other systems in American homes. Natural gas and electricity are used to heat most American homes, electricity to cool almost all.
