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.

What form of geological activity does the great rift valley represent
Savatey [412]

Answer: Volcano

Explanation:

The Great Rift Valley is the site of major geological activity that stretches from Mozambique to the Middle East. Scientists believe that Africa and the Arabian Peninsula were joined together before they were separated by a process called rifting.

As the Earths tectonic plates begin to tear apart in this region, molten magma emerge from the earth crust to fill the void resulting in a separation.

Geologist estimates that the phenomenon which resulted in the great rift valley started 25 million years ago and gave rise to the Red sea. It is believed that the Indian Ocean flooded into the rift to form the Red Sea.

The.magma that seeps upward to fill crustal voids in the rift valley emerge mainly via volcanoes. Hence, many active and semi-active volcanoes are scattered throughout the region referred to as the Great Rift Valley, including Mount Kenya and Mount Kilimanjaro.
