Study Notes
The Universe
- The Big Bang Theory: The universe began as an extremely hot and dense point around 13.8 billion years ago, expanding rapidly from a singularity and continuing to expand to this day.
- The first few minutes after the Big Bang saw temperatures and pressures high enough for nuclear fusion to occur, forming the lightest elements, mostly hydrogen and helium.
- Matter condensed into stars and galaxies through gravitational attraction, with the cosmic microwave background radiation providing evidence for the Big Bang Theory.
The Solar System and the Earth
- The Solar System consists of the Sun, eight planets, their moons, asteroids, comets, and other celestial objects.
- The Earth is the third planet from the Sun and the only one known to support life, with a diverse range of ecosystems including oceans, forests, deserts, and polar regions.
- The Solar System formed around 4.6 billion years ago from a rotating cloud of gas and dust, with gravity pulling material together to form the Sun and the planets.
The Moon and Tidal Phenomena
- The Moon is Earth's only natural satellite and influences various tidal phenomena.
- Tides are caused by the gravitational pull of the Moon and the Sun on Earth's oceans, typically resulting in two high tides and two low tides each day.
- Tidal forces slow down Earth's rotation over time, with spring tides occurring during full and new moons when the Sun, Moon, and Earth are aligned, resulting in higher high tides and lower low tides.
Movements of the Earth
- Earth orbits the Sun in an elliptical path, taking approximately 365.25 days to complete one revolution, causing the changing seasons due to its axial tilt (23.5 degrees) and variations in solar radiation intensity.
- Earth rotates on its axis once every 24 hours, leading to the cycle of day and night, with the Coriolis effect influencing weather patterns and ocean currents.
- Time zones are based on Earth's rotation, with each zone covering 15 degrees of longitude, and the US and Russia having multiple time zones.
Cartography
- Geographical coordinates (latitude and longitude) specify precise locations on Earth's surface, with latitude measuring north-south position and longitude measuring east-west position.
- Map projections represent the curved surface of the Earth on a flat map, with each projection distorting some aspect of reality (shape, area, distance, or direction).
- Maps can display thematic content, such as population density, climate, economic activities, or political boundaries, using various methods like color coding, symbols, graphs, and layering.
Physical Geographic Sphere
- Earth's structure consists of the inner core, outer core, mantle, and crust, with the lithosphere comprising the crust and uppermost part of the mantle, broken into tectonic plates.
- Plate tectonics causes earthquakes, volcanic activity, and the creation of mountain ranges, with divergent, convergent, and transform boundaries.
- Georelief includes terrestrial and underwater relief, with features like mountains, valleys, plains, oceanic trenches, mid-ocean ridges, and continental shelves.
- Internal and external geomorphological forces shape the Earth's surface, including volcanic activity, tectonic movements, weathering, erosion, and deposition.
Atmosphere
- Composition: mainly nitrogen (78%) and oxygen (21%) with trace amounts of other gases.
- Layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere, each with distinct characteristics.
- Weather and climate are influenced by temperature, humidity, precipitation, wind, and atmospheric pressure, with climate being a long-term pattern of these elements.
Hydrosphere
- Surface waters: rivers, lakes, and reservoirs.
- Subsurface waters: groundwater stored in aquifers.
- The World Ocean and its parts: Pacific, Atlantic, Indian, Southern, and Arctic oceans, with distinct characteristics, economic importance, and movements of ocean water, including waves, tides, and currents.
