Earth's Surface Features
- Landforms: Mountains, hills, plateaus, plains, valleys, deserts, and coastal areas.
- Topography: The shape and characteristics of the earth's surface.
-
Earth's Layers: Crust, Mantle, Outer core, Inner core.
- The crust is the solid, rocky outer layer.
- The mantle is a thick, soft layer of hot rock beneath the crust.
- The core is the earth's central part. The outer core is liquid, while the inner core is solid.
- Volcanoes: Openings in the Earth's crust from which magma, gases, and ash erupt.
- Erosion: The process of moving weathered rock and soil from one location to another.
- Weathering: The process that breaks down rocks into smaller pieces.
- Deposition: The process in which eroded material settles in a new location.
- River Features: Tributaries, rapids, waterfalls, floodplains, estuaries, deltas.
- Coastal Features: Beaches, cliffs, bays, and inlets.
- Desert Features: Dunes, canyons.
- Mountain Features: Peaks, ridges, valleys.
Processes Affecting Earth's Surface
- Tectonic Plates: Large pieces of the Earth's lithosphere that move slowly, causing changes.
- Volcanic Activity: The process of volcanoes erupting.
- Earthquakes: The shaking of the Earth's surface due to the movement of tectonic plates.
- Erosion: The wearing away of the earth's surface by wind, water, ice, and other forces.
- Deposition: The process by which eroded material is deposited in a new location.
Earth's Layers
- Crust: The solid, outermost layer of the Earth.
- ** Mantle:** A thick, soft layer of hot rock beneath the crust.
- Core: The central part of the Earth, divided into the outer core (liquid) and the inner core (solid).
Ocean Floor Features
- Continental Shelf: The gently sloping part of the continent that extends into the ocean.
- Continental Slope: The steep slope that connects the continental shelf to the ocean floor.
- Deep-Ocean Trenches: The deepest parts of the ocean floor.
- Mid-Ocean Ridges: Underwater mountain ranges.
- Ocean Basins: Flat areas of the ocean floor.
- Seamounts: Underwater volcanic mountains.
Other Topics
- Weathering: The breakdown of rocks into smaller pieces.
- Erosion: The movement of weathered material by wind, water, or ice.
- Deposition: The laying down of eroded material in a new location.
- Fossil: The remains or imprints of ancient organisms preserved in rock.
- Fossil Fuels: Fuels such as coal, oil, and natural gas, formed from ancient plants and animals.
- Renewable Energy Sources: Energy sources that can be replenished within a short time, such as solar and wind energy.
- Non-renewable Energy Sources: Energy sources that cannot be replenished quickly, such as fossil fuels.
- Formation of fossil fuels: Dead plants and animals decompose under pressure and heat over millions of years to form coal, oil and natural gas.
- Formation of caves: Chemical weathering of rock by groundwater forms caves.
- Acid rain: A form of chemical weathering that damages buildings and other structures.
- Earthquakes: The shaking of the Earth's surface due to the movement of tectonic plates.
- Volcanoes: Openings in Earth's crust where magma, ash, and gases erupt.
- Tsunami: A large wave caused by an earthquake in the ocean.
