ES9 Unit 1: Introduction to Earth Science

What subjects are studied in Astronomy?

• The study of Earth's oceans and their physical and chemical properties

• The universe and everything in it, including galaxies, stars, planets, moons, and other bodies they have identified. They focus on the movement, composition, and structure of bodies in space.

• The study of interactions among organisms and their surroundings, including pollution and energy resources

• The materials that make up Earth and the processes that form and change these materials

What is the difference between how astronomers used to study astronomy to how they study it now? Why is that?

• Before, astronomers merely described the locations of objects in space in relation to each other. Today, they study the entire universe and everything in it. This is because of the advancements in technology.

• Before, astronomers only studied the stars, but now they only study planets. This is because planets are easier to observe.

• Astronomers used to study astronomy by guessing, but now they use astrology. This is because astrology is more scientific.

• Astronomers used to study astronomy at night, but now they study it during the day. This is because the sun is the closest star.

How much of the planet do the oceans cover?

• 3/4ths

• 1/2

• 1/3

• 1/4

What is studied by Earth scientists who specialize in geochemistry?

• They study Earth's composition and the processes that change it.

• They study the movement of tectonic plates.

• They study the formation of clouds and weather patterns.

• They study the behavior of ocean currents.

What does it mean that 'technology is transferable'?

• It means that it can be applied to new situations.

• It means that it is always expensive.

• It means that it cannot be used anywhere else.

• It means that it is only for experts.

Give an example of how technology can make life easier.

• Freeze dried foods last longer than non-freeze dried food.

• Walking to school every day.

• Reading a book by candlelight.

• Writing letters by hand.
