Why do we experience different seasons?
Earth is tilted at its axis and orbit around the sun. It changes the amount of direct sunlight we receive.
Which telescope has provided detailed images of space from outside Earth’s atmosphere?
Hubble Space Telescope
What causes the different phases of the Moon?
The Moon’s orbit around Earth changes how much of its lit side we see
Name the action of Earth spinning on its axis.
Rotation
Identify the only planet known to support life.
Earth
What is the difference between Earth's rotation and revolution?

Name the four terrestrial planets in our solar system and explain one unique characteristic of each.
Mercury – The smallest planet in our solar system.
Venus – The hottest planet in our solar system.

List three significant achievements in space exploration and explain their importance.
1. Heliocentric Model (1500s): Nicolaus Copernicus proposed that Earth and the other planets orbit the Sun, which changed how people understood our solar system.
2. Isaac Newton’s Laws of Motion (1600s): Newton explained gravity and motion, which helped scientists understand how planets and spacecraft move.
3. First Moon Landing (1969): Apollo 11 astronauts landed on the Moon, showing that humans could explore another world.
4. Hubble Space Telescope (1990): Hubble helped scientists learn more about distant stars, galaxies, and the universe.
5. Mars Rovers (1997–Present): Robots explored Mars and collected evidence to help scientists learn whether the planet could have supported life.
