11 answers
Over time, models of the solar system have evolved from geocentric to heliocentric. Initially, ancient civilizations believed that the Earth was the center of the universe, while in the 16th century, Nicolaus Copernicus proposed that the Sun was at the center of the solar system, which later gained acceptance with the advancements made by scientists like Johannes Kepler and Isaac Newton.
consider the creation of our solar system. why did the sun end up at the center? answer in 1 to 2 sentence's
The Sun ended up at the center of our solar system due to the process of gravitational collapse, where a giant molecular cloud collapsed under its own gravity and formed a rotating disk of gas and dust. As the collapse continued, the majority of the mass collected at the center, forming the Sun, while the remaining materials formed the planets and other celestial bodies.
which of the following changes would increase the gravitational pull between the Sun and the Earth?

if the sun was further away from the earth
if the Earth was half its size
if the Earth was closer to the Sun

explain your answer in 1 to 2 sentence's
The changes that would increase the gravitational pull between the Sun and the Earth are if the Sun was twice its size or if the Earth was closer to the Sun. This is because the gravitational force is directly proportional to the mass of the objects involved, hence increasing the mass of the Sun or decreasing the distance between the Earth and the Sun would result in a stronger gravitational pull.
how are Earth and the moon different in regards to atmosphere? explain in 1 to 2 sentences
Earth has a substantial atmosphere composed of nitrogen, oxygen, and other gases that support life and weather patterns, while the moon has a very thin and virtually non-existent atmosphere, containing only trace amounts of elements such as helium and argon.
