10. COMPONENTS OF THE UNIVERSE
The Universe is thought to consist of three
types of substance: normal matter, 'dark
matter' and 'dark energy'. Normal matter
consists of the atoms that make up stars,
planets, human beings and every other
visible object in the Universe.

13. Activity 1: Compare and Contrast. What are the
similarities and differences among these four terrestrial
planets
14. • Venus, Mercury, Earth, and mars are part of the inner terrestrial or
rocky planets. Their composition densities are not too different from
each other.
• Venus is considered to be the Earth’s twin planet. It has a very similar
size and mass with the Earth. Mars is about half the Earth’s size.
• Among the four planets, Mercury is the nearest and Mars is the
farthest from the Sun.
• Rotational speed of Earth and Mars are very similar. Rotational speed
of Venus and Mercury are slow.
• Abundance of liquid water on Earth, hence the blue color. The Earth is
habitable planet.
16. 1. TEMPERATURE
•It influences how quickly atoms and molecules
move.
•Low temperatures cause chemicals to react
slowly. It can also cause the freezing of water,
making liquid water unavailable.
•Life seems to be limited to a temperature range
of -15 degree Celsius to 115 degree Celius
17. 2. ATMOSPHERE
•Traps heat, shields the surface from harmful
radiation, and provides chemicals needed for
life, such as nitrogen and carbon dioxide.
•Earth’s atmosphere is about 100 miles thick. It
keeps the surface warm and protect it from
radiation and small – to medium-sized
meteorites.
18. 3. ENERGY
•Organisms use light or chemical energy to
run their life processes.
• When there is too little sunlight or too few
of the chemicals that provide energy to the
cells, such as iron or sulfur, organisms die.
19. 4. NUTRIENTS
•Used to build and maintain an organism’s body.
•Without them or when they are hard to obtain,
life cannot exist.
•All solid planets and moons have the same
chemical makeup, so nutrients are present.
Those with a water cycle or volcanic activity can
transport and replenish the chemicals required
by living organisms.
Dark matter is completely invisible. It emits no light or energy and thus cannot be detected by conventional sensors and detectors.
Dark Energy - a theoretical repulsive force that counteracts gravity and causes the universe to expand at an accelerating rate.
