Question

Some scientists hypothesize that icy debris arrived on other terrestrial planets in a similar manner to how it arrived on Earth. On Earth, the ice eventually turned to water and water vapor, forming extensive oceans and a life-sustaining atmosphere. But the same is not exactly true for the other terrestrial planets. What are two reasons why?

A. Temperatures on Earth are ideal for water to exist in solid, liquid, and gaseous forms.
B. Magnetic forces generated in Earth’s mantle are directly responsible for Earth’s oceans.
C. The absence of life forms on other terrestrial planets didn’t require a need for water.
D. Earth’s gravity holds the water vapor in Earth’s atmosphere close to its surface.
E.Earth’s solid outer core is sufficiently rigid to keep water above its surface.The Answer is More than 1! thx

Answer 1

A and D for these options

Step-by-step explanation:

My test on PLATO only had A-D options so on my test it was A and C but for this question with these options it's A and D

Answer 2

The correct answers are A) Temperatures on Earth are ideal for water to exist in solid, liquid, and gaseous forms and D) Earth’s gravity holds the water vapor in Earth’s atmosphere close to its surface.

The two reasons why this is not exactly true for the other terrestrial planets are that temperatures on Earth are ideal for water to exist in solid, liquid, and gaseous forms and Earth’s gravity holds the water vapor in Earth’s atmosphere close to its surface.

That is why our beautiful planet Earth is so special in the Solar System. We need to protect it by taking care of the environment and stop the pollution of the air and the water, the destruction of the animal's habitat and putting at-risk wildlife. We have to decisively act on the climate change issue if we want to live many more years on this planet that offer humans plenty of resources.
