Study Notes

Earth and its Habitats

  • Earth's Structure:

    • Core: The center of the Earth, always meaning 'at the centre'.
    • Crust: The hard outer layer of the Earth, similar to bread's crust.
    • External Structure: The visible surface materials.
    • Internal Structure: The hidden materials inside the Earth.
    • Magma: Molten rock.
    • Mantle: The layer below the crust, made up of magma.
    • Ash: Burnt material.
    • Composite Volcano: Volcano built from lava and ash.
    • Crater: A large hole on top of a volcano.
    • Erupt: To shoot out suddenly.
    • Lava: Magma reaching the Earth's surface.
    • Plateau: A flat uplifted area of rock.
    • Risk: The possibility of something happening.
    • Secondary Cone: A small volcano on the side of a larger one.
    • Vent: A hole, like in buildings, to allow air.
    • Coastal Area: A low-lying area along the coast.

  • Earthquakes:

    • Coastal Area: Affected by earthquakes and related events.
    • Earthquake: A shaking of the Earth.
    • Epicenter: The point on the surface directly above the earthquake's focus.
    • Focus: The point inside the Earth where an earthquake begins.
    • Landslide: A mass of rocks and soil sliding down a slope due to vibrations from an earthquake.
    • Transfers: Movement of energy from one place to another, e.g., earthquake energy to waves.
    • Tsunami: A large wave caused when an earthquake occurs under the sea.
    • Wave: A way energy travels, like seismic waves through the Earth.

  • Volcanoes:

    • Ash: Ejected material from eruptions.
    • Composite Volcano: A volcano with layers of material.
    • Crater: The opening from which the volcano erupts.
    • Erupt: To suddenly release material from a volcano.
    • Lava: Magma that has reached the Earth's surface.
    • Plateau: Flat, uplifted area of rock.
    • Risk: The danger during or after an eruption.
    • Secondary Cone: Smaller volcano on the side of a larger one.
    • Vent: The hole from which volcanic material is ejected.

  • Different Habitats:

    • Beak: Part of a bird's mouth.
    • Crack Open: To split open (as in plants or animals).
    • Fins: Used for swimming or movement in water.
    • Gills: Structures to breathe underwater.
    • Strain: A physical or mental stress.
