Study Notes
Earth's Surface and Water Coverage
- 71% of the Earth's surface is covered by water.
Atmosphere
- The stratosphere does not have air vortices, water vapor, clouds, or obvious changes in temperature.
Composition of Air and Ocean
- Helium is NOT found in natural air.
- 98% of the ocean's volume consists of water, while 2% consists of nitrogen, oxygen, and other dissolved gases.
Hydrosphere and Lithosphere
- The mechanical effect of the hydrosphere on the lithosphere is primarily caused by erosion and sedimentation.
Ocean Topography
- The maximum depth of the ocean is approximately 11,000 meters and is found in the Mariana Trench.
Lithosphere Composition
- The lithosphere is mostly composed of igneous and metamorphic rocks.
Continental Shelf
- The outer limit of the continental shelf is called the continental slope.
Soil and Sedimentary Layers
- Soil covers another crust called subsoil.
- Sedimentary layers in the lithosphere contain harder rocks, such as sedimentary rocks, and are formed from the accumulation of sediments.
Lithosphere Formation
- The lithosphere forms the Earth's crust.
Rivers and Oceans
- Rivers and tributaries carry sediments and nutrients to the oceans.
Mineral Formation
- Minerals are formed in the earth as a result of natural and chemical activities without human intervention.
Mountain Peaks
- The highest mountain peak is Mount Everest, with a height of approximately 8,848 meters above sea level.
Continental Platform and Deep-Sea Shelf
- The continental slope connects the continental platform and the deep-sea shelf.
