Title: The Planets and the Sun


1
The Planets and the Sun
  • Study guide

2
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 ______.
    This layer is blanketed by the suns atmosphere,
    or _____. It is the only part we can see during
    a solar eclipse. Dark areas on the surface of
    the sun are ______. These dark areas can produce
    ______. Brief bursts of energy from the suns
    surface. As this energy is released a
    fast-moving stream of particles, known as _____
    is thrown into space.

photoshere
corona
sunspots
Solar flares
Solar wind
3
Solar system, planet, asteroids, comets, orbit,
law of universal gravitation.
  • A large object that moves around a central star,
    such as the sun is a ______. The path the object
    takes around the sun is its _____. Small rocky
    objects, known as _____ orbit the sun in a path
    between Mars and Jupiter. _____, are 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 ______ ______.
    According to the __________ all objects are
    attracted to all other objects.

planet
orbit
asteroids
comets
Law of universal gravitation
Solar System
4
What is the source of all energy in the solar
system?
5
Magnetic Storms that distrub communication
systems on Earth are caused by
  • Particles thrown off by the sun.

6
How does energy from the sun travel?
  • In waves.

7
Solar energy is produced by..
  • fusion

8
Know these layers of the sun
  • Core
  • Radiation Zone
  • Convection Zone
  • Photosphere

9
How do we know the Sun rotates?
  • Here is a hint

Sunspots move across the sun, disappear and
reappear on the other side.
10
How is Earth different from other planets?
11
Rings around the planets are made up of..
  • Rock , ice, dust

12
Planets that are closer to the sun orbit
  • Faster than outer planets.

13
What did a space probe find that could mean water
once existed on Mars?
  • Sedimentary rocks.
  • Why?
  • (What is a
  • Sedimentary
  • rock?)

14
Earth and Mercury are both alike because they
  • Are made of rock

15
What energy waves are released by the sun?
  • Infrared waves
  • X rays
  • Radio waves

16
How are asteroids like comets and how are they
different?
  • 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.
