Match the following internal layers of the Earth with their composition:
Crust = Rocks and minerals, including granite, basalt, and sedimentary rocks Mantle = Hot, viscous rock Outer Core = Iron (~85%) and nickel (~10%) Inner Core = Iron-nickel alloy
Match the following internal layers of the Earth with their characteristics:
Crust = Solid, ranging in thickness from 5-70 km Mantle = Hot, viscous, and solid but able to flow slowly over time Outer Core = Liquid and responsible for generating the Earth's magnetic field Inner Core = Solid and with a pressure of over 3.5 million times that of the atmospheric pressure at sea level
Match the following internal layers of the Earth with their depth ranges:
Crust = 5-70 km Mantle = 35 km to 2,900 km Outer Core = 2,250 km Inner Core = 1,220 km in diameter
Match the following internal layers of the Earth with their divisions:
Crust = Continental and oceanic crust Mantle = Upper and lower mantle Outer Core = No divisions Inner Core = No divisions
Study Notes
Earth's Internal Layers
Crust
- Outermost solid layer of the Earth
- Thickness: 5-70 km
- Composition: rocks and minerals
- Density: 2.5-3.0 g/cm³
- Divided into two types: continental and oceanic crust
Mantle
- Thick layer of hot, viscous rock beneath the crust
- Thickness: 2,900 km
- Composition: olivine, pyroxene, and garnet
- Density: 3.3-4.3 g/cm³
- Divided into upper and lower mantle
Upper Mantle
- Thickness: 400 km
- Temperature: 500-900°C
- Composition: peridotite and eclogite
- Lithosphere: outermost solid portion of the mantle
Lower Mantle
- Thickness: 2,500 km
- Temperature: 2,000-3,000°C
- Composition: bridgmanite and ferropericlase
- Divided into three layers: upper, middle, and lower
Outer Core
- Liquid layer of iron and nickel
- Thickness: 2,250 km
- Temperature: 4,000-6,000°C
- Composition: iron (~85%), nickel (~10%), and lighter elements
- Responsible for generating Earth's magnetic field
Inner Core
- Solid, iron-nickel alloy at the center of the Earth
- Thickness: 1,220 km
- Temperature: 5,000-6,000°C
- Composition: iron (~98%) and nickel (~2%)
- Solid due to extremely high pressure
