• Water erosion is the process by which soil and rock particles are transported by the flow of water.
• Chemical weathering involves the breakdown of minerals by water or air, resulting in changes to the rock's composition.
• Physical weathering is the breaking down of rocks into smaller pieces without changing their composition.
• The main types of weathering are physical, chemical, and biological.
• Erosion is the process by which soil and rock particles are worn away and moved elsewhere by wind, water, or ice.
• The movement of tectonic plates can cause earthquakes, volcanic activity, and mountain building.
• Mechanical weathering occurs when rocks break apart due to physical forces such as freezing and thawing cycles, temperature fluctuations, and plant root growth.
• The three main types of physical weathering include freeze-thaw action, abrasion, and expansion/contraction.
• Freeze-thaw action occurs when water seeps into cracks in rocks and freezes, causing them to expand and break apart.
• Deposition is the process by which sedimentary material settles out of moving water or air and accumulates on land.
• Biological weathering refers to the effects of living organisms on rocks, including root growth and microbial activity.
• Rainwater can dissolve some minerals in rocks, leading to chemical weathering.
• Weathering occurs when rocks break apart due to external forces such as temperature fluctuations, freeze-thaw cycles, and plant roots.
• Tsunamis are large waves caused by underwater earthquakes that can travel long distances across oceans.
• Abrasion involves the movement of solid particles along the sea floor, while attrition is the breaking down of rock fragments by collisions with other objects.
• Coastal erosion is the wearing away of coastlines over time through processes like abrasion, attrition, corrosion, solution, and hydraulic action.
• Deposition is the final stage where eroded materials are deposited at their new location.
• Erosion is the movement of soil and rock fragments from one place to another.
• Sediments are loose particles that have been transported from their original location and deposited elsewhere.
• Chemical weathering involves the breakdown of rock through chemical reactions with substances like carbonic acid and oxygen.
• Acid rain forms when pollutants like sulfur oxides and nitrogen oxides combine with moisture in the atmosphere, creating acids that can leach minerals from rocks.
• Chemical weathering involves chemical reactions between rock minerals and substances like oxygen, carbon dioxide, sulfuric acid, and nitric acid.
• Sediments are deposited at low energy areas like deltas, estuaries, and bays.
• The three main types of weathering include physical (mechanical), chemical, and biological.
• Chemical weathering changes the mineral composition of rocks.
• Physical weathering occurs when rocks break apart due to physical forces such as freezing and thawing or expansion and contraction caused by temperature changes.
• Igneous Rocks - Formed from molten magma or lava cooling and solidifying
• Rock cycle - The process whereby rocks change over time through different stages including sedimentation, metamorphism, and erosion
• Weathering occurs due to differences in temperature, pressure, water availability, wind speed, and vegetation cover.
• Biological weathering is caused by living organisms such as plants, animals, fungi, and bacteria.
• Physical weathering breaks down rocks into smaller pieces without changing their mineral composition.
• Biological weathering is caused by living organisms such as plants, animals, fungi, bacteria, and algae.
• Rock fragments produced by mechanical weathering become smaller and more rounded due to abrasion and impact during transportation.
• Biological weathering occurs as plants grow into cracks and crevices in rocks, causing them to expand and break apart over time.
• Physical weathering is caused by changes in temperature, water, ice, wind, gravity, and plant roots.
• Rivers carry large amounts of sediment, which they deposit on floodplains during periods of high flow.
• The process of sedimentation occurs as water slows down or stops moving, allowing sediments to settle out.
• Metamorphic Rocks - Result from existing rocks being subjected to high temperatures and pressures
• Metamorphic Rocks - Result from existing rock being subjected to high pressure and/or heat, causing it to recrystallize into new minerals
• Sedimentary Rocks - Composed of sediments that have been compacted and cemented together over time
