Each rock type possesses unique characteristics that influence the landforms it creates. For example, granite’s resistance to weathering leads to distinct landforms compared to the easily eroded clay.
Climate
Water is a crucial agent in temperate climates, while ice dominates cold regions. The climate significantly impacts the weathering and erosion processes.

The Sun
Structure of the Sun
Core: The Sun’s core is where nuclear fusion occurs due to high temperatures. It is the power generator of the Sun.
Radiative Zone: In this zone, energy-carrying particles (photons) try to escape, but their journey can last 100,000 years. This is because these photons are continuously absorbed and re-emitted in different directions.
Convective Zone: This zone experiences the phenomenon of convection. Columns of hot gas rise to the surface, cool, and then descend again.
Photosphere:
