Explain how the ages of the rocks on the ocean floor support the theory of seafloor spreading​
Dafna11 [192]

The Drilling sample of the Seafloor spreading theory helped in determining rock ages on the floor of ocean.

Explanation:

The formation of crusts of ocean by the process of volcanic eruptions in the ridges of the middle ocean is the theory of seafloor spreading proposed by Hammond Hess. The movement of tectonic plates continuously forms sea floors through spreading of seafloor.  The several evidences in support of this theory has been seen, of which some are – molten material eruptions, magnetic stripes in rocks and rock ages.

The drilling evidence is the final one that was proved by taking samples of rock by drilling in ocean and by bringing them with pipes. The observation of these rocks proved that older rocks were collected from farther ridges and youngers are found in the central ridges.

Which statement describes an important role of carbon dioxide in Earth's atmosphere?
MrRissso [65]

Answer:Plants use carbon dioxide to make food

Explanation: Carbon-dioxide plays a very important role in sustaining life on Earth.

Plants use carbon-dioxide and water for photosynthesis in presence of sunlight and chlorophyll to produce food and oxygen.

CO₂ + H₂O →  O₂ + glucose (food)

This food is consumed by the animals and oxygen is used for respiration. Animals use energy from the food to do work and exhale back carbon-dioxide.
