1.Earth is the only planet in the Solar System with plate tectonics
The outer crust of the earth is broken up into different regions with different sizes known as tectonic plates. The tectonic plates float on top of magma interior of the Earth and move in any direction required. When two plates collide, an overlap will occur allowing for the formation with fresh crust.
- Earth is almost a sphere
Earth is shaped like a flattened sphere in which through many years of investigation and use of astronomy.
- Earth is Mostly Iron, Oxygen and Silicon
Earth is made of 32.1% iron, 30.1% oxygen, 15.1 % silicon, and 13.9% magnesium. Most of the iron is located at the core of the Earth.
- 71% of the Earth’s surface is covered in water
“Blue Planet” is what this planet was called after astronauts first went to space, in which Earth was mostly seen as blue. Only 29% of the earth is solid crust that is located above sea level.
- The Earth’s atmosphere is 10,000 km LONG!!
The atmosphere is thickest in the first 50km from the surface, but it reaches out to about 10,000 km into space. Five main layers create the atmosphere them being (Stratosphere, the mesosphere, the thermosphere, and the Exosphere)
6.The Earth’s Molten Iron Core Creates a Magnetic Field
Earth is like a big magnet with poles at the top and bottom near the actual geographic poles. The magnetic field it creates is effective over a long distance. The magnetic field forms a region called the magnetosphere. The heat created by convection motions of conducting materials to generate electric currents.
- Earth Doesn’t take 24 hours to rotate on its axis
It actually takes 23 hours, 56 minutes and 4 seconds for the earth to rotate once on the axis, the sun’s effect on the earth compensates for those lost 4 minutes.
- A year on Earth isn’t 365 days
It’s actually 365.2564 days, it being an extra couple of minutes creates the need for the leap year once every four years.
