9 Things You Probably Didn’t Know About The Earth: How much do you really know about the place you call home? For most of us, the answer is “not much.” We take for granted the things we see every day and don’t think to question them. But when you look at the world around you critically, you realize just how little you know.
This blog post will explore 9 things you probably didn’t know about the Earth. From the forces that keep it in orbit to the creatures that live on it, there’s a lot to learn about our planet. So read on and expand your horizons!
9 Things You Probably Didn’t Know About The Earth
The Earth is not round.
The first thing you should know about the Earth is that it is not round. In fact, it is an oblate spheroid, which means it is slightly flattened at the poles and bulges at the equator. The Earth’s rotation causes this shape. The second thing you should know about the Earth is that it is not stationary. It revolves around the Sun in an elliptical orbit. Additionally, the Earth rotates on its axis, which causes day and night.
The Earth’s atmosphere is slowly fading away.
The Earth’s atmosphere is slowly fading away. The Sun constantly emits a stream of particles called the solar wind. These particles interact with the Earth’s atmosphere, slowly eroding it. This process is known as sputtering.
Over time, the solar wind will eventually strip away all of the Earth’s atmosphere. Without an atmosphere, the Earth would be a dead planet. The loss of our atmosphere would have disastrous consequences for life on Earth.
Fortunately, we still have billions of years before this happens. In the meantime, we can do our part to protect our atmosphere and ensure that it lasts for future generations.
There are other planets similar to Earth.
There are other planets similar to Earth in terms of size and composition. These include Mars, Venus, and Mercury. However, there are significant differences between these planets and Earth.
For example, Mars has a much colder surface temperature than Earth due to its distance from the Sun. Venus has a much hotter surface temperature than Earth due to its proximity to the Sun. Mercury’s surface temperature varies greatly depending on where it is in its orbit around the Sun.
The Earth has two Moons.
It’s common knowledge that the Earth has one moon. But did you know that it has two?
The first moon, called the “true” moon, is the one we usually think of when we think of the Earth’s moon. It orbits our planet at an average distance of 384,400 kilometers and has a diameter of 3,476. This moon is believed to be about 4.5 billion years old.
The second moon, called the “dark” or “shadow” moon, is much smaller than the actual moon and orbits much closer to Earth. It was discovered in 2013 and is thought to be just 100 million years old.
So why haven’t we seen this second moon before? Well, it’s very faint and difficult to spot with the naked eye or even most telescopes. It’s so dark that it reflects less than 1% of sunlight!
What else do we know about this mysterious second moon? Scientists believe that a collision between two asteroids probably created it. And since it’s so close to Earth, it may one day be pulled into our planet’s orbit and become a permanent satellite!
The Earth’s core is boiling.
The Earth’s core is boiling. The innermost part of the Earth’s core is about as hot as the Sun’s surface. The outer part of the Earth’s core is much more relaxed but still pretty hot. The temperature at the center of the Earth’s core is thought to be around 6000 degrees Celsius!
The Earth’s magnetic field protects us from solar winds.
The Earth’s magnetic field is responsible for protecting us from solar winds. Solar winds are a stream of charged particles that flow from the Sun.
These particles are capable of causing damage to the Earth’s atmosphere and surface. Without the Earth’s magnetic field, we would be bombarded by these particles, and our planet would be uninhabitable.
The Earth is the only planet in our solar system with liquid water.
The Earth is the only planet in our solar system with liquid water. This is because of the Earth’s unique position in the solar system. The Earth has located just the right distance from the Sun. If it were any closer, the water would evaporate. If it were any further away, the water would freeze.
The presence of liquid water on Earth makes it a unique and special place in the universe. Life as we know it could not exist without water. Water is essential for all known life forms. It helps regulate the body temperature of animals and plants, transports nutrients and minerals, and lubricates joints.
There is a lot of evidence that suggests that there might be other planets with liquid water out there, but we have yet to find any definitive proof. If there are other habitable planets, they are probably very similar to Earth in size, position, and composition.
Life on Earth started in the oceans.
It is believed that life on Earth first began in the oceans. This is because the first life forms were simple, single-celled organisms called prokaryotes.
Prokaryotes are still found in the oceans today and make up a large percentage of marine life. The earliest prokaryotes were likely similar to modern bacteria and archaea. These organisms are thought to have arisen from chemical reactions in the early Earth’s oceans.
Life on Earth began even earlier than the first prokaryotes. Some scientists believe that certain chemicals, such as RNA, may have catalyzed the formation of life.
Others believe that meteorites or comets may have brought organic material to Earth that kickstarted the process of life. Regardless of how it started, it is clear that the oceans have played a vital role in the development of life on our planet.
Earthquakes happen when plates move.
Earthquakes happen when plates move. The Earth’s outermost layer comprises several large pieces called plates. These plates move around on the Earth’s surface, sometimes bumping into each other. When they do, it can cause an earthquake.
