Weathering Weathering is the degrading of earth rocks, soils
and their minerals through direct contact with the planet's atmosphere. Weathering occurs in situ, or "with no movement", and then it should not to be confused with erosion, which involves the movement and disintegration of rocks and minerals by agents such as water, ice, wind, and gravity.
Erosion Erosion is the carrying away
or displacement of solids (sediment, soil, rock and other particles) usually by the agents of currents such as, wind, water, or ice by downward or down-slope movement in response to gravity or by living organisms (in the case of bioregion).
Continental Drift In the 11th century, the
Persian geologist, Abū Rayhān Bīrūnī (973-1048), observed the geology of India and discovered that the Indian subcontinent was once a sea and later became land. He attributed this the drifting of alluvium rather than continental drift.
Plate tectonics Plate tectonics (from Greek τέκτων,
tektōn "builder" or "mason") describes the large scale motions of Earth's lithosphere. The theory encompasses the older concepts of continental drift, developed during the first half of the 20th century, and seafloor spreading, understood during the 1960s.
Climate Change Climate change is any long-term
significant change in the “average weather” that a given region experiences. Average weather may include average temperature, precipitation and wind patterns.
