What causes the different phases of the Moon that we observe from Earth?
What causes the different phases of the Moon that we observe from Earth?
The different phases of the moon are caused by the changing angles at which we view the lit portion of the Moon as it orbits the Earth.
Explain why the Earth experiences seasons.
Explain why the Earth experiences seasons.
The Earth experiences seasons because its axis is tilted. This tilt causes different hemispheres to be closer to the sun at different times of the year.
How long does it take the Earth to go around the Sun, and what is this path called?
How long does it take the Earth to go around the Sun, and what is this path called?
It takes the Earth 365.25 days to orbit the Sun. This path is called an orbit.

Flashcards
Inner Planets
Inner Planets
The four inner planets in our solar system, Mercury, Venus, Earth, and Mars, are relatively small and primarily composed of solid rock.
Outer Planets
Outer Planets
The four outer planets, Jupiter, Saturn, Uranus, and Neptune, are significantly larger than the inner planets and primarily composed of gas.
Seasons
Seasons
The Earth's tilt on its axis causes different hemispheres to receive varying amounts of sunlight throughout the year, resulting in seasons.

Study Notes
Inner Planets
- Mercury, Venus, Earth, and Mars are small and mostly solid
- These planets are smaller than outer planets
Outer Planets
- Jupiter, Saturn, Uranus, and Neptune are large and mostly made of gas
- These planets are larger than inner planets
Moon & Tides
- The Moon orbits Earth in 29.5 days
- The Moon is lit by the Sun, but we don't always see the entire lit side
- This is because the Moon's orbit changes, resulting in different shapes (phases)
- The Moon's gravity affects tides, creating high tides
Satellite
- A satellite is something that orbits a planet
- The Moon is Earth's only natural satellite
Seasons
- Earth is tilted on its axis
- When the Northern Hemisphere is tilted towards the sun, it is summer
- Summer days are longer and sun’s rays are stronger
A Year
- Earth orbits the Sun
- One orbit takes 365.25 days
- Every four years, an extra day is added to the calendar (leap year)
Day & Night
- Earth spins on its axis (anti-clockwise)
- This rotation takes 24 hours
Weight
- Weight is a force caused by gravity
- Weight is calculated by multiplying mass by gravitational field strength
- Gravitational field strength on Earth is always 10 N/kg
Order of the Planets
- Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
Comets
- Comets are made up of rock and ice
- They are found beyond Pluto
- Comets have a long tail
Asteroids
- Asteroids are made up of rock and metal
- They orbit between Mars and Jupiter
