Celsius.
True
False
Question 2 pts
The photosphere is:
the middle layer of the sun
the visible surface of the sun
the inner most area of the sun
Question 3 pts
Sunspots:
a violent explosion on the Sun's sufrace
are cooler, darker areas on the Sun's surface that have lower temperatures than surrounding areas, and they usually
occur in pairs
, is a stream of radiation emitted by a solar flare
Question 4 pts
The moon produces its own light as it passes through the moon phases.
True
False
Question 5 pts
Tides are the regular rising and falling of Earth's surface water in response to gravitational attraction from the
Moon and Sun.
True
False
Question 6 pts
The Earth's tilt on its axis accounts for the seasons on Earth.
True
False
Question 7 pts
Spring tides are extreme tide events that happen when the Earth, Moon, and the Sun are aligned; happens at
full and new moon phases.
True
False
Question 8 pts
We live in the Milky Way Galaxy.
, True
False
Question 9 pts
The Hubble Space Telescope orbits the Earth at an altitude of 589 km and collects data in visible, infrared, and

True
False
Question 12 pts
A star generates energy by nuclear fusion reactions in its core.
True
False
Question 13 pts
, All stars are born from collapsing clouds of gas and dust, often called nebulae or molecular clouds. Over the
course of millions of years, these protesters settle down into a state of equilibrium, becoming what is known as

True
False
Question 14 pts
Our sun consists almost entirely of the elements hydrogen and helium.
True
False
Question 15 pts
Hubble's Law states that the farther away a galaxy is, the faster it is moving away from us. This leads us to the
hypothesis that the universe is expanding.
True
False
Question 16 pts

True
False
Question 17 pts
Globular clusters are groups of tens to hundreds of thousands of stars held tightly together by gravity.
True
False
