12 Lessons in Chapter 3: Earth in the Solar System: Homework Help
Galaxy Formation: Spiral, Elliptical & Irregular Galaxies

1. Galaxy Formation: Spiral, Elliptical & Irregular Galaxies

This lesson explains how galaxies form, starting with the Big Bang. You'll also learn about the solar nebula hypothesis and three galaxy types, including spiral, elliptical, and irregular galaxies.

Structure of the Sun

2. Structure of the Sun

Discover the layers of the sun, including the core, radiative zone, convective zone, photosphere, chromosphere, and corona. Find out which layers you can see from Earth. Investigate what sunspots and solar flares are.

Stages of the Sun's Life Cycle

3. Stages of the Sun's Life Cycle

Discover our Sun, the provider of energy for life on Earth. Learn how the Sun was born, how it lives as a main sequence star, how it will age into a red giant and how it will die as a white dwarf.

Star Formation: Main Sequence, Dwarf & Giant Stars

4. Star Formation: Main Sequence, Dwarf & Giant Stars

Learn how stars are born, beginning with a protostar. Then learn about stars in later stages of life, including main sequence stars, brown dwarfs, red giants, and black holes.

Types of Stars by Size, Color and Life Cycle

5. Types of Stars by Size, Color and Life Cycle

Learn to identify the different sizes and colors of stars and how they relate to the star life cycle. In this lesson, we'll talk about spectral classification, how many stars there are of each type and the approximate color of the different classes of stars.

Astronomical Units & Light Years: Definition & Examples

6. Astronomical Units & Light Years: Definition & Examples

After watching this video, you will be able to explain why we need special astronomical ways of measuring distance. You will also be able to state the meaning of the terms astronomical unit, light year and parsec. A short quiz will follow.

Stars as a Source of Light: Definition & Explanation

After reviewing this lesson, you will be able to explain how stars are a source of light, and why we see other objects in our solar system. A short quiz will follow.

Inner Planets of the Solar System: Mercury, Venus, Earth & Mars

8. Inner Planets of the Solar System: Mercury, Venus, Earth & Mars

Take a tour of the four inner planets: Mercury, Venus, Earth and Mars. Known as the terrestrial planets, find out what makes each of them unique and how they are different from the outer planets, the gas giants.

Outer Planets of the Solar System: Jupiter, Saturn, Uranus, Neptune

9. Outer Planets of the Solar System: Jupiter, Saturn, Uranus, Neptune

Take a tour of the outer planets of our solar system: Jupiter, Saturn, Uranus, and Neptune. Find out what makes each of these gas giants unique and learn about Pluto, a dwarf planet.

Dwarf Planets of the Solar System: Pluto, Eris, Haumea & Ceres

10. Dwarf Planets of the Solar System: Pluto, Eris, Haumea & Ceres

Discover why Pluto had to leave the league of planets and was downgraded to a dwarf planet. Learn the definitions for planet and dwarf planet. Find out about the currently classified dwarf planets in our solar system: Pluto, Eris, Ceres, Haumea and Makemake.

Asteroids, Meteorites & Comets: Definitions and Characteristics
