Layers of the Earth
The outer most layer of the Earth composed of different minerals
Crust
The crustal layer that is mostly made of granitic rocks
Continental crust
A mechanical wave that travels through the Earth. It can be generated by earthquakes, volcanic eruptions, magma movement and many more.
Seismic waves
What is the total percentage of that you can found in the Land Hemisphere?
53% water
The large puzzle like pieces of the Earth
Tectonic Plates
The layer of the Earth that is divided into two and has a liquid and solid composition
Earth's Core or Core
The crustal layer mostly composed of basaltic rock
Oceanic crust
The discontinuity that discovered that the P - waves are slower in the upper crust layer than the lower crust layer that increases in speed
Conrad discontinuity
About what percentage covers the whole Earth in water?
About 71% water
A land formation in crust openings or weaknesses that lets hot melted rocks from the mantle rise
Volcanoes
The layer of the Earth that produces Electromagnetic field that helps us from protecting from the Sun's violent rays.
A landform that forms when continental and oceanic crust collides to each other and sinking
Oceanic trenches or trenches
What was produced by the s-waves when it reached the boundary between Mantle and Outer core?
S-wave shadow zones
What is the percentage of the water locked in ice and glaciers?
The evidence of continental drift theory that says that the shape of the continents are puzzle like
Puzzle fit evidence or matching coastlines evidence
The layer of the Earth that is divided into two, and composed of molten rocks
Mantle
What are the two process that constantly builds and destroys the oceanic crust?
Seafloor spreading and subduction
What was discovered by Inge Lehmann during his observation of the p-waves that reached the boundary of the outer and inner core?
Refraction and reflection of p-wave
The percentage of water in Water Hemisphere
89% water

What is the discontinuity that you can found in the middle of the upper and lower mantle?
Repetti discontinuity
