It affects the earth's crust as it is related to the action of divergent boundaries where two plates are moving apart causing the continents to move. This is linked to convection currents as hot rocks lower in the mantle are forced up to the surface by gravitational forces, cooling, sinking and then heating again, helping the movement of the rigid plates
Natural convection currents are caused by density differences in a fluid due to variations in temperature. When a fluid is heated, it becomes less dense and rises, creating a current. As the fluid cools, it becomes more dense and sinks, completing the convection cycle.

Ocean currents are primarily driven by wind patterns, differences in water temperature and salinity, the Coriolis effect, and gravitational forces from the moon. These forces influence the direction and strength of ocean currents, shaping their flow around the globe. Human activities, such as climate change and pollution, can also impact ocean currents by altering water temperature and disrupting natural processes.
convection currents in the mantle provide the basic driving forces for plate motions.
The planet Saturn has. These little moons affect ("shepherd") the rings of Saturn due to gravitational forces.

convection currents
Wegener proposed two forces for the movement of continents: gravitational pull caused by the Earth's rotation, and the force generated by the mantle convection currents beneath the Earth's crust.

Unequal heating of Earth's surface: Differential heating of the Earth's surface by the sun creates temperature and pressure differences that drive convection currents. Rotation of Earth (Coriolis effect): The rotation of the Earth causes moving air or water to be deflected, which influences the direction of convection currents. Gravitational force: Gravity plays a role in pulling denser, cooler air or water downwards, while lighter, warmer air or water rises, initiating convection currents.
convection currents in the upper mantle
The layer of the Earth where convection currents occur is the mantle. These currents are generated by the heat from the Earth's core, causing movement in the semi-fluid mantle material. The movement of these convection currents is one of the driving forces behind the movement of tectonic plates on the Earth's surface.

Tides are caused by the gravitational forces on Earth from the Moon and the Sun.
