- Earth's crust is ~32 km thick under continents and ~8 km thick in other areas
- Earth's crust is broken into pieces called plates
- The mantle is the thickest layer, composed of hot, dense rocks
- The outer core is liquid nickel and iron
- The inner core is solid, under immense pressure (3,000,000x surface pressure)
Earth's Movement
- Earth revolves around the sun in 365 days and 6 hours (leading to leap years)
- Earth rotates on its axis in 24 hours, creating day and night
- The Gregorian calendar is the current calendar system

- Yuri Gagarin was the first person to travel into space
Ecosystems
-
Ecosystems consist of biotic (living) and abiotic (nonliving) components, including plants, animals, microorganisms
-
Examples include the Amazon rainforest, which is a high biodiversity area and provides ~20% of the Earth's oxygen
-
Mutualism describes species benefiting from each other.
-
Predation involves one species hunting and consuming another.
-
Parasitism involves one species benefiting at the expense of another (the host).
-
