why do we call the earth our home

Earth is the third planet from the sun and the fifth largest in the solar system. Earth is 92,955,820 miles (149,597,891 kilometers) away from the sun. At 7,917. 5 miles (12,742 km), Earth's diameter is just a few hundred kilometers larger than that of Venus. The four seasons are a result of Earth's axis of rotation being tilted more than 23 degrees. The length of a year on Earth is 365 days, 6 hours, and 16 minutes. The length of a day on Earth is 23 hours and 56 minutes. Oceans at least 2. 5 miles (4 kilometers) deep cover nearly 70 percent of Earth's surface. The minimum weather temperature on Earth is -126 degrees Fahrenheit (-87. 8 degrees Celsius) and the maximum weather temperature on Earth is 136 degrees Fahrenheit (57. 8 degrees Celsius). Fresh water exists in the liquid phase only within a narrow temperature span (32 to 212 degrees Fahrenheit/0 to 100 degrees Celsius).


This temperature span is especially narrow when contrasted with the full range of temperatures found within the solar system (from -400 to 900 degrees Farenheit/-300 to 500 degrees Celcius). The presence and distribution of water vapor in the atmosphere is responsible for much of Earth's weather.
how Earth came to be called so. Firstly, its important to understand that nearly every language has its own name for the planet. Its called terra in Portuguese, dnya in Turkish and aarde in Dutch, just to name a few with their own etymology. However, the common thread in all languages is that they were all derived from the same meaning in their origins, which is ground or soil. The modern English word and name for our planet Earth, is said to go back at least 1,000 years. Just as the English language evolved from Anglo-Saxon (English-German) with the migration of certain Germanic tribes from the continent to Britain in the fifth century A. D, the word Earth came from the Anglo-Saxon word erda and its germanic equivalent erde which means ground or soil.


In Old English, the word became eor(th)e or ertha . There is speculation that the origins of the word may be from an Indo-European language base er which produced more modern adaptations of the word used in languages today. What is certain though is of all the Planets names, Earth is the only one in our solar system that does not come from Greco-Roman mythology. All of the other planets were named after Greek and Roman gods and goddesses.


Translations of the Bible into English was one of the earliest recorded use of the name Earth God called the dry land Earth, and the waters that were gathered together he called Seas. And God saw that it was good. (Genesis 1:10) Earth is the only planet in the Solar System with plate tectonics. The outer crust of the Earth is broken up into regions known as tectonic plates. These are floating on top of the magma interior of the Earth and can move against one another. When two plates collide, one plate can go underneath another. Earth doesnt take 24 hours to rotate on its axis. It takes 23 hours, 56 minutes and 4 seconds to completely rotate around its axis; If you add up that little motion from the Sun that we see because the Earth is orbiting around it, as well as the rotation on its axis, you get a total of 24 hours.


Everyone knows that the Earth has 1 Moon. But did you know there are 2 additional asteroids locked into a co-orbital orbits with Earth? Theyre called 3753 Cruithne and 2002 AA 29. The first doesnt actually orbit the Earth, but has a synchronized orbit with our planet, that makes it look like its following the Earth in orbit, but its actually following its own, distinct path around the Sun. The 2002 AA travels in a horseshoe orbit around the Earth that brings it close to the planet every 95 years. Earth is gradually slowing down. Every few years, an extra second is added to make up for lost time. In other words, millions of years ago, a day on Earth would have been only 20 hours long. It is believed that, in another million years time, a day on Earth will be 27 hours long.
