Select an option to attempt

Explanation

All of the listed phenomena (1-6) are responsible for bringing dynamic changes on the surface of the Earth.

Electromagnetic Radiation Sunlight drives weather patterns, influences temperatures, and is crucial for plant life (photosynthesis).

Geothermal Energy Heat from the Earth's core fuels volcanic activity, drives plate tectonics, and shapes landforms.

Gravitational Force The Moon's gravity creates tides in our oceans, influencing coastlines and erosion.

Plate Movements The movement of tectonic plates causes mountain formation, earthquakes, and continental drift, constantly reshaping the Earth's surface.

Rotation of the Earth Earth's rotation creates day and night cycles, affecting weather patterns and influencing wind and ocean currents.

Revolution of the Earth Earth's revolution around the Sun causes seasons, impacting temperatures and weather patterns globally.

These forces act together in a complex interplay, constantly sculpting and reshaping the Earth's surface over vast timescales.
