The migration of the Moon away from the Earth is mainly due to the action of the Earth's tides. The Moon is kept in orbit by the gravitational force that the Earth exerts on it, but the Moon also exerts a gravitational force on our planet and this causes the movement of the Earth's oceans to form a tidal bulge.
Which of these statements is most likely correct about the stars?
Star 2 attracts Star 1 with a greater gravitational force than Star 1 attracts Star 2.
No, because Third Newton Law states that both forces are equal in magnitude.
Earth exerts almost equal gravitation force on both the stars.
No, because the Universal Gravitational Law, estblished by Newton, states the atraction force to two masses is proportional to the product of the masses.
Star 1 attracts Star 2 with a greater gravitational force than Star 2 attracts Star 1.
No (same reason for the first statement)
Earth exerts greater gravitation force on Star 2 than on Star 1.
Right. This is the correct statement. Given the mass of Star 2 is greater than the mass of Star 1, by the Universal Gravitational Law, the earth exerts greater gravitational attraction on Star 2.
Basically the Earth is layered because of gravity. The earth formed in the molten state. The liquid iron which is very dense fell to the center. The rest of the earth is made up of silicate materials with SiO2 being the main component.

Many thousands of acres of mangrove forest have been destroyed to make way for rice paddies, rubber trees, palm oil plantations, and other forms of agriculture.
Hope this helps :D have an awesome day!
