1. Which label should be used to describe the energy of the hammer in the first
Rudik [331]

Answer:

A. is the answer

Explanation:

The hammer in the first position is raised and ready to hit the nail on the head. This is called potential energy. It has a lot of energy stored inside of it but it won't get used until we allow it to hit the nail. That is why it is not kinetic energy but only potential. Think of it just as when we say something has the potential to do something.

Use evidence from the section titled I'm Very Young to explain the difference in age between rock samples found on the Atlantic
White raven [17]

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.
