Question

question 4
what are some of galileos contributions to astronomy? (select all that apply)

• gave credibility to the heliocentric model.
• observed the phases of venus, which are similar to the phases of the moon.
• discovered 4 of jupiters moons.
• gave credibility to the geocentric model.

question 5
this is what astronomy studies:

• the ways the objects beyond our planet interact with one another.
• all of the above
• the history of the universe.
• objects beyond our planet earth

question 6
earth is easily distinguished from other planets by the large amount of liquid water it has.

• true
• false

Explanation:

Analyze Galileo's contributions

Using the History of Astronomy knowledge point

• Galileo's telescopic observations provided strong evidence supporting the Copernican heliocentric model, thereby discrediting the geocentric model.
• He observed the phases of Venus, which showed it must orbit the Sun.
• He discovered the four largest moons of Jupiter (Io, Europa, Ganymede, and Callisto).

Define the study of Astronomy

Astronomy is the scientific study of celestial objects, space, and the physical universe as a whole. This encompasses:

• Studying objects beyond our planet Earth (stars, planets, galaxies, etc.).
• Studying the ways these objects interact with one another (gravity, radiation, orbits).
• Studying the history, origin, and evolution of the universe.

Therefore, all of the individual statements are correct, making "all of the above" the correct choice.

Evaluate Earth's distinguishing features

Earth is unique among the planets in our solar system because its surface is covered by approximately 71% liquid water. No other planet in our solar system possesses large, stable bodies of liquid surface water. Thus, the statement is true.
