attashe74 [19]

Answer:

In these experiments the control group is compared with the comparison group.

The control group will sometime be in the presence of carbon dioxide, and will be controlled, where the analyst or researcher will take an expert position and then will compare it evolutionarily with the comparison group that the ideal would be that there is not ever a carbon dioxide

Explanation:

If we have two poison ivy research groups that are representative of the poison ivy that the researchers are looking to investigate the results will have much better credibility and will be more reliable.

On the other hand, the comparison of the two groups makes it possible to rigorously analyze whether or not poison ivy grows in the presence of this gas.

Alex73 [517]

The answer is;

A crack forms in oceanic crust.

Volcanoes erupt under the ocean.

Molten rock rises up through the crust.

New material pushes older rock away from the ridge.

Seafloor spreading occurs in divergent boundaries where two tectonic plates are moving away from each other. As the plates diverge, the void is filled up by upweling magma from the mantle. This causes an eruption at the boundaries causing a cascade of mountains along the ridge.  Therefore, the closer to the ridge you get, the newer the crust is.
