Motion and Brightness
What is the definition of an revolution?
The time it takes for an object to orbit another object.
These two elements are most abundant in the sun.
Hydrogen and Helium
This is a piece of rock moving through space
Meteoroid
Draw what what we perceive as a Waxing Gibbous moon Phase
Stars that are the same size as the sun will become these when they begin to run out of fuel.
Red Giants
What is the term for the following definition:
The turning of an object around an imaginary axis running through it.
This is the process responsible for the radiation and energy release by the sun.
Nuclear Fusion
An object that ranges in size from around 10km to 530km wide, composed of rock and metal.
This is the outer shadow of a celestial object.
Penumbra
Which stars can become a neutron star upon their death.
Stars that are between 10-30 times larger than the Sun will become Neutron stars after their death.
The retrograde motion of Mars is an example of:
Apparent Motion
When the sunlight is more intense in the southern atmosphere, there is this season in the northern hemisphere.
winter
An example of meteoroids that enter Earth's atmosphere and burn up. Provide the name and an example.
Meteor and shooting stars
Describe what occurs during a Solar Eclipse.
Without the pressure that nuclear fusion generates, a star's core collapses due to this.
Based on the H-R diagram, beta centauri appears in the upper left quadrant, while proxima centauri appears in the lower right quadrant. Based on what we know about luminosity and temperature relating to size and colour, what can be said about beta centauri compared to proxima centauri?
Beta Centauri is larger and hotter than proxima centauri.
These are the result of the interaction of the sun's magnetic field with the Earth's atmosphere.
Auroras
What are the two tails of comets made of
One of gas/water vapour, one of dust.
Describe what occurs during a Lunar Eclipse.
When the Earth is between the Sun and the Moon.
Before becoming a black hole, a red giant more than 30 times larger than the sun will do this.
Explode into supernova.
Absolute Brightness.
The Earth's spins at this angle on a tilted axis.
23.5°
This is a meteoroid that passes through Earth's atmosphere and reaches the ground without burning up.
Explain how there can be high tide at two opposite ends of the Earth at the same time.
This can occur because the Moon exerts gravity not only on the water, but on the surface of the Earth itself. On the side of the Earth closest to the Moon, the gravitational pull of the Moon pulls the water towards the Moon causing high tide. This pull is also exerted on the surface of the Earth, pulling the surface towards the Moon as well. Resulting in high tide on the opposite side of the Moon.
This can also occur when the Earth is in between the Sun and the Moon, resulting in the gravitational pull of the Sun causing high tide on one side of the Earth, while the Moon is causing high tide on the other side.
The endpoint of a star depends on this.
The mass of the star.
