Explanation:

The inner planets differs from the outer planets mostly and mainly in terms of their sizes and composition.

Inner planets are also know as the terrestrial planets. They are the first four planets closest to the sun. They are mostly solids with rocky masses.

The outer planets are located beyond the asteroid belts. They are the last four planets before the Kuiper belt objects. These planets are also called Jovian planets predominantly made up of gases.

What does the author predict about the future of the Earth's mantle? Do you support his educated guess? Use complete sentences t
Masja [62]

The earth's mantle will not change in the future because this region is safe from the intervention of human beings.

<h3>What happens in the Earth's mantle?</h3>

The transfer of heat and material in the mantle helps us to determine the landscape of Earth. Activity in the mantle moves the plate tectonics, that contributes to volcanoes, seafloor spreading, earthquakes, and building of mountains.

So we can conclude that the earth's mantle will not change in the future because this region is safe from the intervention of human beings.

Which of the following elements is the least reactive metal? Sodium, Rubidium, Chlorine, and Magnesium.​
LuckyWell [14K]
First off chlorine is not a metal so you can ignore that one.

Sodium and Rubidium are in group 1 of the periodic table and Magnesium is in group 2.

Group one metals are more reactive than group two because it is harder for the group two metals to lose their 2 valence (outer most) electrons.

As you go down group 1 there is an increase in the reactivity this is because as you go down there is an increase in the atomic radius which leads to more shielding. This weakens the electrostatic forces of attraction making it easier to lose the outermost electrons, therefore they are more reactive.
