What can be either a precursor to a star or the remains of a star

nebula

What is the most expansive layer of the Earth

The Earth's mantle comprises the bulk of the Earth.

How were large mountain ranges such as the Himalayas produced

collision of tectonic plates

What is the point in space and time where gravity is infinitely strong and matter is infinitely dense

a singularity

Approximately how long ago is the big bang thought to have occurred

13.5 billion years

Which Italian mathematician and astronomer was forbidden by authorities to teach his ideas

Galileo Galiili was forbidden by authorities to teach his ideas.

How are volcanoes that have not erupted in recorded history classified

What type of combustion fuels produces the greenhouse gas carbon dioxide

All carbon based fuels produce carbon dioxide when burned. These include:

  • fossil fuels (coal. oil, natural gas)
  • alcohols
  • bio-fuels (wood, charcoal, waste burning including cremation)
  • specialty industrial fuels (acetylene etc.)
  • carbon monoxide

Coal and petroleum are the two primary fossil fuels. Oxidizing methane also releases CO2, but that is 25 times better than releasing methane, itself an even more potent greenhouse gas.
As of 2006 what is a body in orbit around the sun that has a defined sufficient mass gravity and a clear orbit
