7 things that make life possible on Earth. Earth information. life on earth How water exist on Earth
MILKY WAY GALAXY IS SUITABLE FOR LIFE.
 |
It has also been proven that galaxies (like stars) have habitable zones, where star systems are located in spiral arms very close to or very far away from the core, will be exposed to too much radiation for life to emerge. ...
THE LOCATION OF SOLAR SYSTEM IN THE MILKY WAY IS FAR FROM MANY THREAT. ...
The location of our solar system is about 25,000 years to the galactic center and 25,000 l8ght year away from the rim.. . So, basically, if you were to think of our galaxy as a big record, we would be the spot that's roughly halfway between the center and the edge.
OUR SUN IS STABLE, LONG LASTING, AND METAL RICH STAR.
The Sun is currently classified as a "main sequence" star. This means that it is in the most stable part of its life, which converts the hydrogen present at its core into helium. For a star shape, this phase lasts a little over 8 billion years.
THE EARTH IS JUST AT THE RIGHT DISTANCE FROM THE SUN.
The Earth orbits the Sun 100,000 times closer to the Ort Cloud at an average of 92,55,807 mi (149,597,870 mi). The distance of the Sun from the Earth is called an astronomical unit or AU, which is used to measure distances across the entire solar system.
JUPITER AND SATURN
The two gas giants that is ( Jupiter and Saturn ) helped stabilize the solar system, helping the Earth and other internal, rocky planets to run continuously from large, fast-moving objects, the researchers said. ...
THERE'S WATER ON EARTH.
Most of Earth's water is believed to have come from asteroids, which affected the planet in the earliest times of its history. Image via NASA / Don Davis. The surface of the very young Earth was initially an ocean of magma. ... Most of Earth's water came from asteroids, but some came from solar nebula.
About 71 percent of the Earth's surface is covered by water, and the oceans hold about 96.5 percent of all the Earth's water. Water is present in the form of water vapor in the air, in rivers and lakes, in snowflakes and glaciers, in the ground as moisture and aquifers, and even in you and your dog. The water is never sitting empty.
EARTH HAS A MAGNETIC FIELD.
In a sense, yes. Earth is made up of layers with different chemical compositions and different physical properties. Some permanent magnetization occurs in the Earth's crust, and the Earth's core generates its own magnetic field, retaining the core of the field on which we measure.
