Earth is geologically active because of its Internal heat.
What processes shape Earth's surface?
Impact cratering, volcanism, tectonics, and erosion.
How does Earth's atmosphere affect the planet?
Earths atmosphere shields us from solar radiation and makes the green house effect possible.
Was there ever geological activity on the Moon or Mercury?
Both had volcanism and tectonics but are now geologically dead because of their small size.
Who was Evangelista Torricelli?
An Italian physicist and mathematician, known for his barometer.
What is plate tectonics?
A theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle
Is there heat inside Earth?
Yes.
What is convection?
The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat
What is conduction?
The process by which heat or electricity is directly transmitted through a substance whenthere is a difference of temperature or of electrical potential between adjoining regions, without movement of the material
What is radiation?
The emission of energy as electromagnetic waves or as moving subatomic particles.
