When Earth was very young, its surface was molten due to intense heat from the formation process. The surface cooled over time, leading to the formation of a solid crust. Volcanic activity was common, shaping the early landforms and releasing gases that eventually formed the atmosphere.
What else can I help you with?
What type of rock can only form on or near earths surface?
Sedimentary rocks are the type of rocks that can only form on or very near Earth's surface. Sedimentary rocks form from weathering processes that occur on Earth's surface.
What extends to 85 km above earths surface?
The exosphere is the outermost layer of Earth's atmosphere, extending up to 10,000 km above the surface. It is a very thin layer where the atmosphere transitions into space.
Why are there almost no extrusive ultra-basic rocks in earths crust?
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
What is the uppermost layer of the earths atmosphere?
The uppermost layer of the Earth's atmosphere is the exosphere. It extends from about 500 km above the Earth's surface to about 10,000 km. It gradually transitions into outer space and contains very few gas molecules.
What igneous rocks form below Earths surface?
Igneous rocks that form below Earth's surface are called intrusive or plutonic rocks. These rocks are formed from the solidification of magma beneath the Earth's crust. Examples include granite, diorite, and gabbro.
Why is difficult to determine earths structure?
Because Earth is very very large and we live just on the very surface.
Why do we need to conserve gold silver and platinum?
Because there is very little of them at the Earths surface.
What is meant by earth surface is very young?
well it means that the earth is young it small
Which layer of the atmosphere is furthest from earths surface?
Cirrus clouds are very high in the atmosphere making then furthest from the Earth's surface. They are very thin and wispy in appearance.
How did earth surface look like in the Cenozoic era?
The Cenozoic era's surface was very bumpy and that when the Earth was flat. When the world started getting round Earths surface started getting flat, but that when there was a lot of earthquakes, which wiped out all the dinasours and made them exstinct.
If One percent of ozone reduction causes what to the earths surface?
Ozone is very very important. Even 1% reduce can cause huge harm.
What effect can a very large eruption have on earths climate?
It will cool the earth's surface as radiation from the sun is blocked from entering the atmosphere
When volcano lava cools at the surface?
When magma cools at the surface of the Earth, it cools very quickly and hardens on the Earths crust. However, it continues flowing underneath, forming interesting textures.
What type of rock can only form on or near earths surface?
Sedimentary rocks are the type of rocks that can only form on or very near Earth's surface. Sedimentary rocks form from weathering processes that occur on Earth's surface.
Where is salt rock found?
Salt is found in oceans and seas all over the world.it is commonly found in earths surface in very arid climates
What extends to 85 km above earths surface?
The exosphere is the outermost layer of Earth's atmosphere, extending up to 10,000 km above the surface. It is a very thin layer where the atmosphere transitions into space.
Why can waves with very low frequency follow the earths surface?
Waves with very low frequencies can follow the earth's surface due to a phenomenon known as ground wave propagation. These waves propagate along the surface, interacting with the terrain and following the curvature of the earth. This allows for long-distance communication at low frequencies.
