A) Which possible origin of Earth’s water provides an explanation for the formation of both the
atmosphere and hydrosphere? (1 point)
Comets brought the ingredients from space.
Volcanic eruptions emitted the ingredients into the surroundings.
Solar nebula formed the ingredients in space.
Asteroids brought the ingredients from space.
Question
4
A)
According to the solar nebula theory, how would water potentially be able to handle the hightemperatures?
(1 point)
Water would solidify on comets and asteroids passing through and be carried away from the heat.
Dust particles and water in the nebula formed a mixture that withstood higher temperatures.
Liquid water would turn into water vapor when exposed to intense heat and condense back to liquid
after cooling.
The hydrogen from solar wind would be able to withstand the heat and combine with oxygen to form
water.

Answer 1

Here are the answers to the questions based on the provided context:

Question 1 Scientists have found that more comets with Earth-like water have originated in the
A) (No answer or list provided, can't determine the answer.)

---

Question 2 Most of the theories about how Earth got its water focus on the idea that water
A) was carried to Earth from space. (This is the most common scientific theory.)

---

Question 3 Which possible origin of Earth’s water provides an explanation for the formation of both the atmosphere and hydrosphere?
A) Volcanic eruptions emitted the ingredients into the surroundings. (Volcanic outgassing is often considered a source for both the atmosphere and hydrosphere.)

---

Question 4 According to the solar nebula theory, how would water potentially be able to handle the high temperatures?
A) Liquid water would turn into water vapor when exposed to intense heat and condense back to liquid after cooling. (This describes the behavior of water in varying temperatures.)
