Important and Interesting Things to Know About Planet Earth

Planet Earth is fascinating and amazing. There are many things we don’t yet know about her, but quite a lot that we do. We live on Earth and we use her resources everyday, but what exactly do you know about it? Today, we are sharing some of the things you may not know about this beautiful planet of ours.

The Earth is not completely round

Earth is not completely round or an exact sphere. Because of the flattened poles and the equator that bulges, Earth has more of an oblate spheroid shape. The Earth consists of an inner and outer core, a mantle (the magma), and the crust (tectonic plates).

Plate tectonics is what keeps us comfortable

Tectonic plates are plates that form the outer crust of the Earth and floats on top of the magma interior. When these plates move, they can bump against each other or one will go underneath the other. This is what usually causes earthquakes. Where the plates pull apart, new crust will form. This is important for the carbon cycle.

The Earth consists of iron, oxygen, and silicon.

The Earth is mainly made up of these three materials. It contains 32.1% iron, 30.1% oxygen, 13.9% magnesium, and 15.1% silicon. The distribution of these materials is different for each layer of the earth. The iron is more in the core, while the oxygen is more in the crust.

A day is not 24 hours exactly

In reality, the Earth takes 23 hours, 56 minutes, and 4 seconds to rotate full circle on its axis. The 4 minutes that we are short, is made up the sun’s movement as it rises.

A year is not 365 days exactly

A year is in actual fact 365.2564 days long. This comma point value is why we need a Leap Year every four years. It adds up to that one extra day.

There is so much more we should all know about this wonderful planet of ours. You will be amazed by the things that the Earth offer us and do for us. As a planet, it is truly fascinating.
