Earthquakes

Epicenter is where the force of the earthquake start.
Focus is the starting point of earthquake under the earth.
Hypocenter is the part underground focus point of an earthquake.
Seismograph is the machine that measure how powerful is the earthquake.


Might ask why earthquakes happen? I'll answer....

When the giant boulders that form the crust of the Earth will move due to plate tectonics, are destined to collide. These blocks of rock in contact failures. Sometimes they slide smoothly against each other in a failure.That could lead to an earthquake.

Other cause of Earthquakes is the movement of Tectonic Plates.

The tremors that can only be detected by seismographs. The Earth's crust is made up of twelve plates of about 70 km thick (American, South American, Eurasian, African, Antarctic, Australian Indo, Philippines, Pacific, Cocos, Caribbean, Arab and Nazca), which are constantly moving from millions of years ago. We can feel small earthquakes almost every moment and develop only 10% of earthquakes happen far from the boundaries of these plates.

What is the Epicenter?

Is where the force of the earthquake start.

How many plates are in the earth?
Twelve plates



Earth's Spheres

Atmosphere is the gas part of the earth like the oxygen, CO2 or nitrogen.

Hydrosphere is the liquid part of the earth like ocean, rivers or lakes.

Lithosphere is the solid part of the earth like rock and minerals.

The earth have two crust and one of this is Continental Crust is where we live on where exist the life like animals, plants and humans everybody in general. The other crust is Continental Crust is all the ocean and where live animals and plants live too.

How many Earth's Spheres we have in the earth? (Name of the spheres)
We have 3 and this are Atmosphere, Hydrosphere and Lithosphere.
Which sphere do we live on?
We live on Lithosphere
