Chapter 1
Section 1.1 Planet Earth
Planets
• Inner planets: Mercury, Venus, Earth, and
Mars (made up of rock)
• Outer planets: Jupiter, Saturn, Uranus,
and Neptune (made up of gases)
• Pluto
Solar System
Organisms
• Organisms- living things
Lithosphere
• Lithosphere- layer of land that forms
Earth’s surface
• Includes: rocks, soil, and sand
Hydrosphere
• Hydrosphere- includes all of the oceans,
lakes, rivers, underground water, and
clouds
Atmosphere
• Atmosphere- layer of air that surrounds
the Earth
How can Earth support life?
• Presence of liquid water
• Liquid water in the hydrosphere stores
heat!
• Atmosphere- air is made up of nitrogen,
oxygen, carbon dioxide, and water vapor.
Water Characteristics
• Water absorbs heat during warm periods
and releases it during cold periods.
• Water on Earth helps maintain a steadier
surface temperature than other planets!
Energy comes from the sun
• Form of waves
• Each type of wave has a different
wavelength and are invisible.
• Visible spectrum can be seen by the
human eye (light)
Light Spectrum
Ecology
• Ecology- interactions among nonliving and
living parts of the Earth
• Word “ecology” comes from the Greek
word “oikos”, meaning “home”.
• So, we can say that ecology is the study of
the Earth, which is the home of living
organisms.
Review!!!
• What parts of Earth make up the
hydrosphere?
• What characteristics of Earth enable it to
support life?
• The temperature of a planet is determined,
in part, by its distance from the sun.
Which planets would you expect to be
warmer than Earth? Which ones would be
colder?
