what happems to all those craters on earth
Yes. They believe that the shifting of the tectonic plates under the earth caused it.
Mercury is called the "iron planet" because it has a high concentration of iron in its core. Scientists believe that the planet formed from the heavy elements, including iron, that were present in the early solar system. The iron content gives Mercury a high density and makes it similar to Earth's core in composition.
They believe the planets formed from a disc of gas and dust called a "protoplanetary disc".
Yes. It has a modest magnetic field that is approximately aligned with the planet's axis of rotation. The field is a planetary dipole, and it is though to be generated in a manner similar to the way the earth is though to generate its magnetic field - dynamo action at or around the core. The strength of the field has been estimated as approximately 1% of Earth's. (see link)
mercury, venus, earth, and mars don't have rings. but some scientists differ whether or not mars has rings, but for now its appears not.
Scientists believe that the molecule that came first in the evolution of life on Earth is RNA (ribonucleic acid).
Scientists believe it does. Yes.
Scientists believe that the Earth is approximately 4.5 billion years old based on radiometric dating of rocks and meteorites.
Scientists believe that global warming is happening to the earth because of the greenhouse effect and carbon dioxide pollution in the atmosphere.
A. Quaternary
bacteria
scientists believe it.
no one cares
Scientists believe that the Earth's core is composed mainly of iron and nickel. It is divided into a solid inner core and a liquid outer core. The heat generated by the radioactive decay of elements in the core is responsible for the Earth's magnetic field.
Yes. They believe that the shifting of the tectonic plates under the earth caused it.
Scientists can never be sure of the exact temperatures at the center of the Earth, because we can not directly travel to the center of the Earth. Some scientists believe it is around 12,500 degrees Fahrenheit.
