Question

question 1 - 5
what are the two primary factors responsible for creating tides on earth?
o distance from the sun and distance from the moon.
o gravitational forces and rotations of the moon on its axis.
o phases of the moon and distance from the moon.
o gravitational forces and rotation of earth on its axis.

Explanation:

Tides are mainly caused by the gravitational pull of the Moon on Earth. The rotation of Earth on its axis also plays a role. As Earth rotates, different parts of it pass through the areas of high and low tide created by the Moon's gravitational force. The Sun's gravitational force also has an impact but to a lesser extent compared to the Moon. The rotation of the Moon on its axis (\(2^{nd}\) option) is not related to Earth's tides. The phases of the Moon (\(3^{rd}\) option) are a result of the Moon's position relative to the Sun and Earth and not a primary cause of tides. While the distance from the Moon (\(1^{st}\) option) can affect the strength of the gravitational pull (as per the inverse - square law \(F = G\frac{Mm}{r^{2}}\), where \(F\) is the gravitational force, \(G\) is the gravitational constant, \(M\) and \(m\) are the masses of two objects, and \(r\) is the distance between them), it is the combination of gravitational forces (mainly from the Moon) and Earth's rotation that are the two primary factors.

Answer:

Gravitational forces and rotation of Earth on its axis.
