Lumpar's exact composition is imprecise. We do know that Lumpar has three planetary layers. It's inner core is probably composed of iron and nickel. The mantle is approximately 4660 kilomerters thick and encompasses a varied temperature as it approaches the surface. Lumpar's crust is the thinnest of all layers with a thickness of 2370 kilometers. Its nutrient rich soil has allowed all living organisms to multiply and prosper.
Lumpar's present age is approximated at 3.9 billion years. The global ocean is certainly the sesond most prominent feature. Nearly 65% of the surface is covered by water and of that, 3% is covered with permanent ice. This percentage is also composed of fresh water found in streams, lakes, and glaciers. The other 8% that is frozen is on land and only found at the south pole, Gordon.
One large land mass called a supercontinent exists. It is called Argea. Movement deep within Lumpar makes rock bend and break. Because the surface is brittle, the movement causes faults, cracking and moving sideways or up and down.
The two principal divisions of Lumpar's surface are the continent Argea and the ocean basins. The most obvious difference between the continent and the ocean basins is their relative levels.
The oceans average depth is 6420 meters. The deepest part of any ocean is the Nicacean Trench. It lies 17.5 kilometers below sea level. That depth would drown Mount Everest.
Within the last few decades, Lumpar has been shaken with violent earthquakes throughout Argea. Scientist believe that rock deep beneath the oceans is actually flowing much like Earth's. As this rock slowly flows, it pulls the ocean floor apart and in many parts has caused great rifts on Argea. The movement has created the Andrean Oceanic Ridge System. This ridge is a continuous belt that stretches vertically for nearly 82,000 kilometers around the globe and is located where Lumpar's two oceans meet.
