Kepler's Laws

100

This law of Kepler states that all planets orbit in an elliptical shape.

What is Kepler's 1st Law? 

200

Which law of Kepler states that planets move faster when they are closer to the Sun compared to when they are further away. 

What is Kepler's 2nd Law? 

300

This law states that planets that are further from the Sun will have a longer orbital period compared to those closer to the Sun.

What is Kepler's 3rd Law? 

400

What is the equation for us to determine the orbital period of a planet? 

What is P²=a³?

500

These laws are used to describe the orbital movement and behavior of the planets within the Solar System.

What is Kepler's Laws of Planetary Motion?

Solar Energy & Radiation

100

This is where majority of the Sun's energy is found.

What is the Sun's Core? 

200

True or False. Radiative material that have longer wavelengths will have more energy compared to those with shorter wavelengths. 

What is False? 

300

Energy from the Sun reaches Earth through...

What is radiation? 

400

This process is how the Sun creates energy using hydrogen and helium atoms. 

What is Nuclear Fusion?

500

True or False. Gamma Rays have the shortest wavelengths and higher energy levels on the electromagnetic spectrum?

What is True?

Earth's Movements

100

The Earth takes 365.25 days to orbit this structure at the center of the Solar System.

What is the Sun? 

200

Earth takes 24 hours to rotate around this pole-like structure.

What is Earth's axis? 

300

Seasons are determined by...

What is the tilt of Earth's axis and its orbital position?

400

These high and low tides occur when the Sun, Moon and Earth are in alignment with one another.

What are Spring Tides? 

500

These moderate tides are caused when the gravitational pull of the Moons are at a right angle.

What are Neap Tides?
