Study Notes

Ecology

Ecology is the study of interactions between organisms and their environment, encompassing biological and physical factors.
Key levels of ecological organization include individuals, populations, communities, and ecosystems.
Factors influencing communities include biotic interactions (e.g., predation, competition) and abiotic factors (e.g., temperature, precipitation).
Biomes are large-scale ecological communities with characteristic flora and fauna adapted to specific climate conditions. Important biomes include forests, grasslands, deserts, and tundra.
Energy flow and nutrient cycling are fundamental processes in ecosystems.
Food webs depict the complex feeding relationships within a community, highlighting the transfer of energy through the ecosystem.

Solar System

The solar system is a gravitationally bound system of the Sun and the objects that orbit it.
The Sun is a star composed primarily of hydrogen and helium.
Planets in our solar system include terrestrial planets (e.g., Mercury, Venus, Earth, Mars) and gas giants (e.g., Jupiter, Saturn, Uranus, Neptune).
Asteroids, comets, and dwarf planets are other celestial bodies found within the solar system.
Comets are icy bodies that release gases and dust as they approach the Sun, often forming a visible tail.
The formation of the solar system is hypothesized to have occurred from a giant cloud of gas and dust.

Milky Way Galaxy

The Milky Way is a barred spiral galaxy containing billions of stars, gas, and dust.
Our Solar System is located in one of the spiral arms of the Milky Way.
The galactic center is a densely populated region with a supermassive black hole.
Stars are formed from clouds of gas and dust in the galaxy.
The Milky Way galaxy is estimated to contain hundreds of billions of stars.
Spiral structure of the galaxy is evident through star distribution patterns.

Nuclear Fusion

Nuclear fusion is the process where two or more atomic nuclei combine to form a heavier nucleus, releasing significant amounts of energy.
This process powers stars, including our Sun.
During nuclear fusion, mass is converted into energy, consistent with Einstein's famous equation E=mc².
High temperatures and pressures are necessary for the fusion process to occur.
The Sun's energy comes from the fusion of hydrogen into helium.

SKA (Square Kilometre Array)

The SKA is a large radio telescope array designed to detect faint signals from the universe.
It will consist of thousands of antennas distributed across multiple countries.
The SKA aims to study phenomena like the formation of galaxies and the early universe.
The SKA will collect data on radio waves from astronomical sources.
Its goal is to revolutionize our understanding of cosmic evolution.

Comet

Comets are icy, small celestial bodies orbiting the Sun.
They consist of dust, rock, and ice.
As comets approach the sun, they release gases and dust, creating a visible coma and tail.
Comets' orbits can be elliptical, parabolic, or hyperbolic.
Comets are remnants from the early solar system.
