Today we are going to learn about the characteristic of the earth and why the continents drifted away from each other.
EARTH ROTATION & REVOLUTION
The earth rotates and revolves around the sun, it completes its rotation around the sun once every 24 hours and its revolution around the sun is completed once in every 365 days.
RESULT OF EARTH ROTATION & REVOLUTION
1: Day and night
As the earth rotates its movement causes day and night in the sense that those facing the sun we experience day light and as it continues its movement we will eventually shift away from the sun and experience darkness. To illustrate emerging you have a ball placed on your table and you flash a touch light on it, will all the part of the ball experience the light? the answer is no, the ball is an opaque body and the light can not penetrate to the other side.
2: Change of season
Earth rotation leads to change of season, this changes happens as the earth travels around the sun each year. Summer happens in the hemisphere closer to the Sun, and winter happens in the hemisphere away from the Sun
3:Earthquake
The movement of the earth causes earthquake, those living in a soft plate zone (under ground rocks are called plates) experience shift of plate which eventual leads to earthquakes. i.e the underground rock tends to move away from each other.
4: Solar eclipse
When the earth rotates and get to the point it intercepts the moon and the sun it leads to solar eclipse
5:Continental drifting
It has been proven by the scientist that African as a continent move away from Atlantic ocean 1cm per year and same is applicable to other continents which gradually move away from each other yearly, this is as a result of earth rotation.

PROOFS OF CONTINENTAL DRIFTING
LIVING ANIMALS: The existing animals found today at the edge of the continents found closer to each other are the same.
FOSSIL PLANTS: The dead remains of plants found at edge of the continent are discovered to be the same
FOSSIL ANIMALS: The dead remains of Animals found at edge of the continent are discovered to be the same
JIGSAW PUZZLE: All of us know the puzzle game, when scatter the game your work is just to fix it. The continent moves away from each other, when you look at the shape of Africa and Europe you can fix it together perfectly.
