Answer:
The factors responsible for Earth's tides are:
- Gravitational pull of the Sun
- Gravitational pull of the Moon
Option a and b are correct.
Step-by-step explanation:
The responsible factors for Earth's tides are:
- Gravitational pull of the Sun: The Sun's gravitational force does influence tides, but its effect is relatively smaller compared to the Moon. The Sun's pull contributes to what is known as the solar tide.
- Centrifugal force from Earth's rotation: The centrifugal force resulting from the Earth's rotation does not directly cause tides. Instead, it acts as a counterforce to the gravitational forces and helps create the bulging effect of the tides.
- Earth's mantle convection: The mantle convection, which refers to the movement of the Earth's mantle, does not have a direct impact on tides. Tides are primarily driven by the gravitational forces exerted by the Sun and the Moon.
- Gravitational pull of the Moon: The Moon's gravitational pull is the primary factor responsible for Earth's tides. The Moon's gravitational force causes a bulging effect on the Earth's oceans, resulting in two high tides and two low tides each day.
In summary, the correct options for the factors responsible for Earth's tides are:
- Gravitational pull of the Sun
- Gravitational pull of the Moon
