Answer:
Statements that are correct are: moons' orbits around planets, the moon has less gravitational force than Earth because it is smaller and has less mass, the Sun's gravitational pull is what keeps the planets in its solar system in orbit, the Sun has more gravitational pull than any planet in the solar system because it has the most mass, the smaller the distance between two objects, the larger the force of gravity between them.
Step-by-step explanation:
Option 1: is correct because all moons are orbiting around planets because the planets are the closest objects that are also larger are influence them the most.
Option 2: is not correct because the snowfall on Earth has much more to do with the conditions on the planet than it has with the orbit.
Option 3: is correct because the moon is much smaller than Earth, and its mass is even smaller proportionally, thus its gravitational force is much smaller.
Option 4: is not correct because the moons don't control the orbits of the planets, but the other way around.
Option 5: is not correct because gravity is the force that keeps people and objects to Earth's surface.
Option 6: is correct because the Sun is the object with the most mass and gravitational pull in the solar system, thus it has a big effect on all objects in it.
Option 7: is correct because the Sun is by far the biggest objects in the solar system, and it also has by far the biggest mass, thus its gravitational pull is incomparably bigger than any other object in the solar system.
Option 8: is correct because the closer the objects are the stronger the gravitational pull between them, and the further away they are the weaker the gravitational pull between them.
