Our Solar System and Its Structure

A set of flashcards to aid in understanding key concepts from the lecture on the Solar System, its structure, and the Sun's influence.

Solar System

The group of celestial objects that orbit the Sun, including planets, moons, asteroids, and comets.

Inner Planets

The four smaller, rocky planets: Mercury, Venus, Earth, and Mars, which are closer to the Sun.

Outer Planets

The four larger planets: Jupiter, Saturn, Uranus, and Neptune, mostly made of gas or ice.

Gravitational Force

The force that holds the solar system together, keeping planets in orbit around the Sun.

Nuclear Fusion

The process by which the Sun produces energy, combining lighter elements to form heavier ones.

Planetary Motion

The movement of planets influenced by the Sun's gravitational force and their own inertia.

Seasonal Changes

Changes in climate on Earth caused by the tilt of the planet and its orbit around the Sun.

Photosynthesis

The process powered by solar energy that allows plants to produce food and oxygen.

Sunspots

Darker, cooler regions on the Sun's surface caused by magnetic activity.

Solar Flares

Sudden bursts of energy from the Sun that release radiation and charged particles into space.

Space Weather

The environmental conditions in space influenced by solar activity that can affect technology and life on Earth.

Auroras

Colorful displays in the sky created when charged particles from the Sun collide with gases in Earth's atmosphere.

Conduction

The transfer of heat through solids, such as the ground.

Convection

The movement of heated air or water that creates currents.

Radiation

The transfer of energy through space without a medium, such as sunlight reaching Earth.

Sustainable Space Exploration

Investigating space with the goal of understanding the universe and developing technology for Earth.
