When Galileo Galilei first used a telescope
What is 1610

How Kepler’s version of the heliocentric model was different from Copernicus’?
What is While Kepler’s model showed the planets moving in ellipses, Copernicus’ model showed the planets moving in perfect circles.

How the Great Red Spot and Great Dark Spot differ.
What is The Great Red Spot is a storm on Jupiter, and the Great Dark Spot represents gaps in the methane clouds on Neptune. Also, the Great Red Spot has always been there, meanwhile the Great Dark Spot disappeared and a new one appeared

Use the nebular hypothesis to explain why the planets all orbit the Sun in the same direction
The nebular hypothesis is the theory that the collapse of a nebula formed the solar system. Since that would be spinning, all of the planets that were formed in it would naturally keep on going due to the inertia and the fact that nothing is going to cause them to stop.

What clouds on Venus are made of
What is carbon dioxide and sulfur dioxide
500
The liquid that is found on the surface of Titan
What is Methane (CH4) and Ethane (C2H6)

The reason that Pluto is no longer a planet
What is In order to be classified as a planet, it has to orbit a star, be big enough so that its own gravity causes it to be shaped as a sphere, be small enough that it isn’t a star itself, and have cleared the area of its orbit of smaller objects. In order to be classified as a dwarf planet, it has to orbit a star, have enough mass to be nearly spherical, not have cleared the area around its orbit of smaller objects, and not be a moon
