Answers

1
Which is false about Outer Planets
Jupiter, Saturn, Uranus & Neptune
Are closest to the sun
Made up mostly of gases
Have many moons and rings
2
A sunspot is a darker spot on the surface of the sun that is hotter
False
True
3
The center of the sun where nuclear fusion happens is called
corona
photosphere
convective zone
core
4
Which is false?
Meteoroid are pieces of rock and metal that travel in space.
Meteor is also known as a shooting star
Pluto is the 9th planet
Comets are celestial objects made of rock and ice
5
The following image shows:
Lunar Eclipse
Solar Eclipse
6
How are stars born?
in clouds of dusts called nebulae that collapses upon itself
Core that is super cold, pulling atoms apart
A mass that pulls apart and cools
7
Constellations are
an observable occurrence in astronomy
a group of stars that form a pattern
our sun
a smaller star pattern seen in a larger star pattern
8
Which is false re: chromosphere
Chromos means coloured
its the hottest layer
is the red layer but can't be seen b/c
9
When a star explodes it does not results in:
Black holes
Supernova
new star and planet systems
Neutron stars (densest material known)
10
How a star evolves depends on its:
mass
coolness
heat
protostar glow
11
Supernova is the violent end of a High Mass star
False
True
12
Which layer is hot plasma oozes towards the surface, cools then sinks towards lower levels
Radiation Zone
Chromosphere
Corona
Convection Zone
13
Revolution creates
night and day
seasons
14
Which is false about the Earth's sun:
is a medium star
the sun will never burn out
emits ultraviolet radiation
98% is composed of H and He
15
Which is false about solar wind:
creates the aurora boreaslis in Northern hemisphere
interacts with Earth's hydrosphere to produce light displays
creates aurora australis in the Southern hemisphere
constant flow of particles, streaming out of the Sun's surfa
16
Rotation of earth creates:
Night and day
Seasons
17
Identify this sun surface feature:
Sunspot
Prominence
Solar flare
Coronal mass ejection
18
The effects of the gravitational field of the moon on the Earth's oceans results
solar eclipse
lunar eclipse
low tides
in 2 tides per day
19
What separates the inner and outer planets
Pluto
Oort Cloud
Asteroid Belt
Black Hole
20
The outer most layer of the sun is seen during a solar eclipse
False
True
21
Which is true about medium Stars
longest lasting star
brightest star
nuclear fusion between Hydrogen and oxygen
our sun is a medium star
22
Inner Planets
Mercury, Venus, Earth & Mars
Have many rings
Have many moons
Jupiter, Saturn, Uranus & Neptune
23
Supergiant is
coldest and least bright star
heating and compression of H & He resulting in expansion
Our sun
smallest start
24
The following image shows:
Solar Eclipse
Luncar Eclipse
25
The following image is of the big dipper. Which is false
asterism: smaller star pattern within a larger consellation
a shape of a bear
apart of Ursa Major
26
Which is false re: low mass stars
last longest 100 billion years
shine brightly as blue stars
use their nuclear fuel more slowly
shining weakly making up most stars in the universe
27
Which is false about high mass stars
Come to a violent end
An example would be Polaris
hotter, brighter and bluer stars
collapse to form Mercury
28
Solar Flare vs. Coronal mass ejection. Which is false:
a mass ejection is more powerful throwing plasma into space
interacts with the Earth's magnetic field creating auroras
has a cooling on Earth's temperature
Both are similar as their an explosion at sun's surface
29
Planets
leftover dust, gases & debris from nebula spin creating disk
have many moons
radiate their own light
nuclear fusion causes the debris to clump together
30
Which is false about the Photosphere?
lowest temperature of all the layers
red originates from this layer
the boundary between inner and outer sun.
the part of sun we can see from Earth
