8. Cardinal
- The 4 cardinal directions are North, South, East, West.

complete. Every four years is a leap year. We have an extra
day.
11. Core/Mantle/Crust
- The Earth has different parts. The core, the mantle, and the
crust.
12. Hydrosphere/Atmosphere/ Biosphere
- The hydrosphere is the mass of water on Earth. The atmosphere
is the gass on Earth. The biosphere where the living things
live.
13. Continent/Island
- Continents are large land masses. Islands are smaller pieces of
land. They are both surrounded by water.
14. Plains/Plateaus
- Plains are flat areas. Plateaus are flat areas too, but they
are higher than 200 metres above sea level.
15. Mountains/Depressions
- Mountains are higher than 600 metres. An example of a mountain
is Mount Everest. Depressions are the opposite of mountains. They
are depressed areas.
16. Beach

- The Rocky Mountains in America is a mountain range. It is also
called the Sierra Nevada, because the Americans were trying to copy
Spain.
21. Relief
- Relief is the different forms on Earth, for example, mountains,
