Earth Crust Facts
Earth's Core
Earth's outer surface or crust is made up of a number of segments or tectonic plates. These plates migrate over the surface, which is liquid outer and an inner core that is concentrated in iron content.covered by 71% water and 29% land. The earth's interior is The inner core is about 1,220 km in radius and primarily comprises of an iron-nickel alloy. Volcanic activity and seismic waves contribute to and arise persistently active and homes a layer of solid mantle, planet's mineral resources.

Terrestrial Planets
The terrestrial planet's generally have a metal primary, most often range of regional components, such as the hills, volcanoes and the canyons. The terrestrial planet's have another environment, consisting of metal, at the center, while the nearby layer is made of silicate.
The term terrestrial planets is used to define a planet which is predominantly composed of silicate rocks. These planets are also The term terrestrial is derived from the Latin word terra meaning Earth,referred to as the rocky planets or the telluric planets.
As a result of the In our solar system, the four inner planet's are terrestrial, in contrast to the four external planet's, fact that these planet's are Earth-like, primarily consisting of silicate substances, and the as well as planet's, primarily consisting of as well as substances.
Planet Saturn Facts
Saturn is the second largest planet after which is 9.8 m/s2. The escape velocity, that is the velocity that must be attained to escape a planet's gravitational pull is 35.5 km/s than the acceleration due to gravity on Earth, for Saturn.Jupiter and has a mass which is 95.152 times earth's mass,At the equator, the acceleration due to gravity on Saturn is 10.44m/s2. It is just a bit more that is 5.6846 x 1026 KgSaturn has an equatorial radius of 60,268 km, which is about roughly 8.55 times Earth's radius.
Four Main Layers of the Earth
The planet Earth comprises several layers. Starting from the Earth's surface, there are four main layers; namely, the crust, the mantle, the outer core and the inner core. The pressure and temperature increases tremendously from the outer layers to the inner layers. Let's take a look at each of them individually.
How was the Earth Formed
The Earth, at the beginning, was very different from what it is now.belief of scientists is that our planet earth was formed some 4.5 billion years ago. It did not have any atmosphere or water bodies. system were all formed due to the contraction of solar nebula.The common The sun, the planets and their satellites in our solar huge mass of spiral cloud made up of dust particles and various types of hot gases.
Earth Mysteries
Earth mysteries refer to some scientific and unscientific ideas which are shrouded in mysterious cultural and religious beliefs.about certain historically important geographical locations on the Earth,when New Age Movement and modern paganism were born.The term 'Earth mysteries'Some elements of society like Earth mysteries include all strange events that happen all over our planet, for which we do monuments, which were once thought to exist, but have no tangible record in history, are explained as a mystery or a myth.
