The Planets and the Sun
Study guide
Solar flares, photosphere, corona, solar wind, sunspots
• The sun is a burning sphere made up of several
layers of gases. The layer we see is the
photoshere
______. This layer is blanketed by the sun’s
corona
atmosphere, or _____.
It is the only part we can
see during a solar eclipse. Dark areas on the
sunspots These dark
surface of the sun are ______.
Solar flares Brief bursts of
areas can produce ______.
energy from the sun’s surface. As this energy is
released a fast-moving stream of particles,
wind
known asSolar
_____
is thrown into space.
Solar system, planet, asteroids, comets, orbit, law of
universal gravitation.
• A large object that moves around a central star,
planet
such as the sun is a ______.
The path the
orbit
object takes around the sun is its _____.
Small
asteroidsorbit the sun in a
rocky objects, known as _____
comets are
path between Mars and Jupiter. _____,
small space objects made of ice, dust, and
gases, orbit the sun, too. The sun and all of the
objects ahat move around it make up the
Law of universal
Solar
System
______
______.
According to the __________
gravitation
all objects are attracted to all other objects.
What is the source of all energy in
the solar system?
Magnetic Storms that distrub
communication systems on Earth
are caused by …
• Particles thrown off by the sun.
How does energy from the sun
travel?
• In waves.
Solar energy is produced by..
• fusion
Know these layers of the sun:
• Core
• Radiation Zone
• Convection Zone
• Photosphere
How do we know the Sun rotates?
• Here is a hint:
Sunspots move across the sun, disappear and
reappear on the other side.
How is Earth different from other
planets?
Rings around the planets are made
up of…..
• Rock , ice, dust
Planets that are closer to the sun
orbit…
•Faster than outer
planets.
What did a space probe find that
could mean water once existed on
Mars?
• Sedimentary rocks.
• Why?
• (What is a
Sedimentary
rock?)
Earth and Mercury are both alike
because they
•Are made of rock
What energy waves are released
by the sun?
• Infrared waves
• X rays
»Radio waves
How are asteroids like comets and
how are they different?
Halley’s comet
• Comets are round with a
tail.
• Asteroids are pieces of
rock with an irregular
shape.
• Comets are ice, dust, and
gases.
• Asteroids move in an
orbit between Jupiter and
Mars.
• Both orbit the sun,
smaller than a planet, are
space objects.
How does the sun help life on
Earth?
• It provides heat, light, and energy which
living things need to grow and survive.
