The main vent is the main outlet for the magma to escape. Secondary vents are smaller outlets through which magma escapes. The crater is created after an eruption blows the top off the volcano
The answer is D:) Happy I could help. Have a great day!
Answer: get smaller
Explanation:
Parallax is the angle formed by the observation lines to a very distant object from two separated points.
The procedure to measure this distance in the case of a star, is based on observing it from two different places far away from each other, and then through trigonometry reach to the following relationship:
(1)
Where:
is the distance from Earth to the observed star (in Parsecs
)
is the earth-sun distance that is equivalent to an astronomical unit (1AU=150000000km)
is the angle of the parallax (in arc seconds
)
Now, the distance to an object (measured in parsecs) is the reciprocal of the parallax (measured in arcseconds). Then, in its simplified mode, the stellar parallax is given by the following equation:
(2)
As we can see, there is an inverse relation between the distance
and the parallax
:
(3)
Hence, if the distance is increased by a factor of 10, the parallax is decreased by a factor of 10.
In other words, the parallax angle gets smaller.
Answer:
You need to show an image for someone to answer that question. Also, this is labelled as geography, i think you meant geometry
They will change shape from the air and rain and fog and other weather.
