What can be either a precursor to a star or the remains of a star
What is the most expansive layer of the Earth
The Earth's mantle comprises the bulk of the Earth.
Approximately how long ago is the big bang thought to have occurred
Which term describes substances that absorb some wavelengths of light
What is the primary focus of mechanical engineering
What type of volcano produced the caldera that covers most of Yellowstone National Park
The Yellowstone volcano is usually called a supervolcano.
Which type of erosion is caused by moving masses of ice
The type of erosion that is caused by moving masses of ice is
called glacial erosion.
Which term refers to an individual who uses basic scientific knowledge to solve real world problems and delelop new technologies
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.
Which of these does not contribute to changing seasons angle of incidence of solar radiation tilt of the earth on its axis distance between the earth and sun or revolution of the earth around the sun
The distance of the Earth from the sun does not contribute to
the changing seasons. Although this distance does change (since the
Earth's orbit is elliptical, not perfectly circular) the amount of
the change is not great enough to affect the seasons. It is the
angle of incidence of solar radiation, which in turn is affected by
the axial tilt of the Earth and its revolution around the sun,
which creates the changing seasons.
What type of engineering would you expect to be invovled in preventing or cleaning or cleaning up pollution
environmental engineer :)
As of 2006 what is a body in orbit around the sun that has a defined sufficient mass gravity and a clear orbit
In 2006, a planet became defined as a body orbiting the Sun that
has a mass of self gravity sufficient enough to make it nearly
round, and has a clear orbit.
A+ planet
What factor most affects the amount of water air can hold-
Water vapor in the air compared to the amount of water vapor
that air could hold at a given temperature.
What is produced by rapid contraction of a very heavy main sequence star that has run out of fuel
What is the term for the time period in the Northern Hemisphere when the sun is directly overhead at 23.5 degrees north latitude
