How long does it take for the solar system to make one orbit around the Milky Way galactic center
250 million years is right for the miky way :) :) :)
What layer of the sun moves heat from the radiative layer to the photosphere
The layer of the sun which moves heat from the radiative layer
to the photosphere is the convective zone.
Which of these determines the intensity of a volcano
The material inside the volcano.(;
During earthquakes which type of fault results when one plate is compressed up onto another plate
What does the third law of planetary motion state
The cubes of the average distances of the planets from the sun is proportional to the squares of their periods.
For about how many years do astronomers believe the solar system has existed
For about 4.6 billion years.
In which layer of the sun is a huge supply of energy produced
Why can scientists not accurately predict where an earthquake will occur
They cannot determine which point along a fault has the most
On the Richter scale an earthquake measuring 2 is ten times stronger than one measuring 3
No, it is the other way round - higher numbers indicate a
stronger earthquake. The factor 10 is correct, though.
Which finding helped provide evidence that the planets orbit around the sun rather than the earth
Venus progresses through phases similar to the Moon.
(Galileo's improvements to the telescope meant that Venus was
visible as a disc rather than a bright spot.)
Which region of the earth allows for the movement of tectonic plates
Which scientist proposed the idea of a sun-centered solar system instead of an earth-centered solar system
Which of these measures and records the vibration of seismic waves produced by an earthquake
Is the asthenosphere a region in the earth where magma chambers form
Yes. That is what the asthenosphere is.
Who proved the planets orbit in elliptical not circular paths
Which term describes the sun and all the objects that revolve around the sun
What is the thin layer of the sun that marks the change between the photosphere and the corona
What is an vent or opening through which volcanic gases and smoke are released
What is a small volcanic mountain wih a narrow base and steep sides
Which of these is a grouping of billions of stars, gas, and dust held together by gravity
