Study Notes
Earth Layers and Composition
- The core is the middle part of the Earth that attracts heavy particles.
- The biosphere is the layer of the Earth where life exists.
- The hydrosphere is the layer composed of water.
- The atmosphere is the outermost layer containing the air we breathe.
- The mantle is the layer surrounding the core, characterized by its plasticity.
- The crust is the outermost solid layer of the Earth, composed of lighter rocks and minerals.
Types of Rocks
- Igneous rock is a type of rock that is lighter and composed of tiny crystals.
- Sedimentary rock is heavier and forms part of the Earth's crust.
Atmospheric Layers
- The troposphere is the layer where weather occurs.
- The stratosphere contains the ozone layer, which protects the Earth from harmful UV radiation.
Key Atmospheric Facts
- Nitrogen is the most common gas in the atmosphere, making up 78 percent, followed by oxygen.
Density and Structure of Earth
- Inside the barysphere, particles settle according to their density, with the heaviest elements sinking to the center, known as the core.
- The Earth's crust is made of two kinds of rocks: lighter continental crust and heavier oceanic crust.
Earth’s Spheres
- Lithosphere refers to the solid part of the Earth (rocks), while the hydrosphere refers to water.
- The atmosphere consists of air, while the cryosphere relates to glaciers and frozen water.
- The troposphere is associated with weather, while the stratosphere relates to the presence of the ozone layer.
