Ch 15: TASC Science: Earth & the Solar System

About This Chapter

Review laws of planetary motion, the seasons in astronomy and how the Earth's orbit impacts climate change. The video lessons and quizzes in this chapter cover these topics and more to help you prepare for the TASC Science exam.

TASC Science: Earth & the Solar System - Chapter Summary

Prepare for questions related to Earth and the solar system on the TASC Science test with help from our online lessons and quizzes. The videos include topics related to:

  • Kepler's laws of planetary motion and the eccentricity of ellipses
  • Law of Universal Gravitation
  • Orbits
  • Effects of orbit and tilt on climate change
  • Cycle of the seasons

This chapter includes multiple entertaining videos and self-assessment quizzes to teach and reinforce concepts related to the solar system. The transcripts include vocabulary terms to emphasize the major points, and the end-of-chapter test can be used to help you gauge your comprehension.

Kepler's Three Laws of Planetary Motion

1. Kepler's Three Laws of Planetary Motion

Find out about the interesting life and major contributions of Johannes Kepler. This lesson will also teach you how to find out how long it takes a planet to revolve around the sun!

Kepler's Laws, Ellipses, and Eccentricity

2. Kepler's Laws, Ellipses, and Eccentricity

This lesson will discuss Kepler's First Law of Planetary Motion; define an ellipse, focus, major axis, semimajor axis, and eccentricity; and explain what they have to do with astronomy.

The Law of Universal Gravitation: Definition, Importance & Examples

3. The Law of Universal Gravitation: Definition, Importance & Examples

Gravity is what pulls us toward Earth, but it's also what pulls Earth toward us. This is explained by the law of universal gravitation, which describes how all objects in the universe have this important force between them.

How Orbits Are Influenced by Gravity & Energy

4. How Orbits Are Influenced by Gravity & Energy

This lesson will explain how potential energy, kinetic energy, speed, and gravity are linked to the orbital motion of planets in our solar system. It will also define aphelion and perihelion.

How Earth's Orbit & Tilt Impacts Climate Change

5. How Earth's Orbit & Tilt Impacts Climate Change

After completing this lesson, you will be able to explain how the earth's orbital shape and tilt affects climate change. We'll explore both historical climate change and current global warming. A short quiz will follow.

The Cycle of the Seasons in Astronomy

6. The Cycle of the Seasons in Astronomy

This lesson will explain to you why the Earth has different seasons, what the equinoxes and solstices are, their names, and if the distance the Earth is from the Sun influences the seasons.
