Erosion and transport - The rock cycle - KS3 Chemistry.

Weathering is the breakdown of rocks at the Earth’s surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material. There are three types of weathering, physical, chemical and biological. Erosion is the process by which soil and rock particles are worn away and moved.

Weathering, disintegration or alteration of rock in its natural or original position at or near the Earth’s surface through physical, chemical, and biological processes induced or modified by wind, water, and climate. During the weathering process the translocation of disintegrated or altered.

Chemical Weathering. Chemical weathering - mainly occurs in warm and wet climates. Water, oxygen and acid can all weather rocks away. They breakdown rocks by dissolving or reacting with some of the minerals in the rock. Water attack. Water itself can cause chemical reactions with some rocks.

Physical Weathering - mainly occurs in deserts and high mountains. Change in temperature can break up rocks. When rocks are subjected to continuous hot and cold spells, they expand and shrink. Most rocks are made from mixtures of minerals. These expand and shrink at different rates. This causes stress to build up in rocks. Eventually, they crack and crumble away.

Facts about Forces. A force may push or pull something, making it move. Forces may make things start, stop, speed up or slow down. Gravity is a type of force which pulls things towards the centre of the Earth. Friction is a type of force that slows things down. Air Resistance is a type of friction. Magnets have two poles - north and south. Magnets attract some metals, such as iron and nickel.
