1
Crust: The outermost layer of Earth is the crust. It is relatively thin compared to the other layers and primarily consists of solid rock, minerals, and sediment.
2
Mantle: Earth's greatest layer sits underneath the crust. Semi-solid rock flows slowly throughout geological time. Earth is mostly mantle.
3
Outer Core: The outer core surrounds the mantle and is primarily composed of liquid iron and nickel. It is responsible for generating Earth's magnetic field.
4
Inner Core: At the very center of Earth lies the inner core, which is believed to be a solid ball of iron and nickel due to extreme pressure and high temperatures.
5
Oxygen: Oxygen is the most abundant element in Earth's crust, making up about 46.6% of its mass. It combines with other elements to form various minerals and rocks.
6
Silicon: Silicon is the second most abundant element in Earth's crust, comprising about 27.7% of its mass. It is a key component of many minerals, including quartz and feldspar.
7
Iron: Earth's most abundant element is iron. It's essential to Earth's core and found in crustal minerals.
8
Aluminum: Aluminum is a common element found in Earth's crust, contributing to the formation of various rocks and minerals.
9
Calcium: Calcium is essential for the formation of many minerals, such as calcite and limestone, and plays a vital role in the structure of Earth's crust.
