Thermal Convection, ridge push and slab pull are believed to be the
processes that cause plate tectonics to move.
Thermal convection is a process when the core of the Earth’s heat is
transferred to Earth’s surface by mantle.
Ridge push is when the mantle wells upward
due to convection and raises the edge of spreading oceanic plates. Since the
plates are higher at the spreading center, they are forced downhill because of
gravity as a result, the ocean floor is flatten.
Slab pull is the part of tectonic plates’
motion which can be accounted for through its subduction.

Possession of a gene sequence linked with cancer makes specific cells more likely to grow abnormally.
Cancer is the name given to a collection of related diseases. Cancer is more than one type of disease. In cancer, as a result of genetic mutations, this regulatory process malfunctions, resulting in uncontrolled cell proliferation. CAD, Stroke, Respiratory illness, COPD are all diseases related to cancer. Inherited genetic mutations play a major role in about 5 to 10 percent of all cancers.
When cancer cells break away from a tumor, they can travel to other parts of the body through the bloodstream or the lymph system. Cancer is hard to treat in later stages because it probably has already spread through out the body.
