If you stick a pencil through Earth at the point of rotation, these 2 points are the north/south poles. Geographically, it’s where longitude lines converge.
Earth scientists compare the lithosphere to a thin, solid and brittle eggshell encasing our inner planet or a thick piece of wood that dries and breaks.
It’s difficult to pinpoint an exact definition for the “geosphere” because it’s used in several different ways. But here are 2 ways to define the geosphere.
This list of Earth statistics provides all the numbers of our home planet. For example, here are size, rotation, density, temperature, orbit, age and more.
What brings order on Earth is gravity. For all matter, it’s always at work. This is how gravity works for ocean tides, planet formation and escape velocity.
Lucky for us, Earth is in the Goldilocks zone. The range where liquid water persists is 0.99 to 1.7 AU. But it doesn’t necessarily mean life or water exists.
Planet Neptune is the farthest planet from the sun at 4.495 billion kilometers from the sun. Neptune has some remarkable facts like its 14 moons and tilt.
We all know planet Saturn for its iconic rings. But there’s more facts about Saturn like its weather, Titan and its the lightest planet in the solar system.
The gas giant known as Jupiter is the largest planet in our solar system. Other interesting facts include its 79 moons, weather patterns and huge auroras.
Earth’s moon was formed at the same time that Earth did. Interesting moon facts include its gravity is 1/6 of Earth and temperature range of -173°C to 127°C
The giant impact hypothesis models the formation of our moon. It starts with a Mars-sized object hitting Earth. This object (moon) still remains in orbit.
Today, we’re exploring facts about the sun. First, you have to realize the enormous size of the sun. It’s so big that nearly 1300 Jupiters can fit the sun!
What’s the history of the universe? Follow us on a journey that starts with the Big Bang. All the way to the formation of stars, galaxies and eventually us.
Hubble galaxy classification assigns a class to galaxies based on their visual appearance. These classes of galaxies are ellipticals, lenticulars and spirals
Galaxies are just large accumulation of stars. For example, we live in the Milky Way galaxy. It houses about 200 billion stars including Alpha Centauri.
