Astronomy: The Earth’s Role in (Outer) Space
1. Draw the hierarchy of the universe universe-made up of billions of galaxies – made up of billions of stars – some of those stars have planetary systems (like our Sun, planets orbit around the Sun)
2. Describe three ways that the Sun makes life possible on Earth.a. lightb. heatc. food (plants make food using the Sun’s energy, photosynthesis)
3. The Earth is not stationary (it does not “stand still” in space. Explain the four major motions of Earth in space).a. Rotation – Earth rotates around its own axis at an angle of 23.5 degrees (basketball spins on its axis)b. Revolution – Earth (and all planets) make one complete “lap” around the Sunc. Precession – the Earth’s axis points to a different point in the night sky every 13,000 yearsd. Nutation – Earth wobbles around its precessional axis (caused by tides, which are caused by moon’s pull
of gravity on Earth)
Multiple-Choice Review:

CHALLENGE QUESTION:
Lithosphere: The Rock Cycle
1. Draw the rock cycle below. Include the following forces that transform rock from one form to another: extreme heat, pressure, compaction, cementation, gravity, etc. [check]
2. Define the lithosphere (what two layers comprise or make up the lithosphere?): layer of Earth made up of the crust and upper mantle
Name: _______________________________ Freshwater
3. Label the four layers of the earth [in order top to bottom: crust, upper and lower mantle, outer core, inner core]
4. In the table below, fill in each layer of the earth and write one characteristic of each (besides where it is located).
Name of Layer One characteristic (fact)
Crust 5-70 km thick (thinnest layer; varies in thickness)
Mantle 2890 km thick; magnesium and iron
Outer Core 2260 km thick; iron and nickel
Inner Core 1220 km thick; SOLID iron (and some nickel)
*heat/temperature and pressure increase as you move down from crust to core*5. Create an analogy to describe the Earth and its layers.
For example:The earth is like an appleThe crust is like the skin because it is thin and on the outsideThe mantle is like the flesh because it is the largest layer and is a soft solidThe outer core is like the outside of the seeds because it is towards the inside The inner core is like the inside of the seeds because it is the solid, innermost part
Now, create your own!The earth is like a _______________________The crust is like the ____________________ because ________________________________________The mantle is like the ___________________ because _______________________________________The outer core is like the ________________ because ________________________________________The inner core is like the ________________ because ________________________________________[creativity]
6. Use the words PANGAEA, CONTINENTAL DRIFT, and MOVEMENT to describe the theory of continental drift (textbook):Alfred Wegner’s theory that the continents were once joined together in one giant landmass (named Pangaea). The theory states that 200 million years ago, the continents started breaking apart and drifted to their current locations.
7. Why didn’t people believe Alfred Wegener when he proposed continental drift (the answer is NOT that he did not have enough evidence) (textbook): Wegener said that fossils on coasts of South America and Africa (between
Name: _______________________________ Freshwaterthem the Southern Atlantic Ocean) were similar; however, people argued that erosion continually changes coastlines over time. Scientists rejected this theory because Wegener could not provide a FORCE that would cause those continents to move across the globe.
8. Draw a picture illustrating how convection currents work in the mantle.
Heat increases as you travel down from the crust to the core. Hotter magma at the base of the mantle is less dense and rises, while cooler denser magma nearer to the crust sinks back down, and the cycle continues.
9. How do convection currents contribute to plate movement?The upper mantle and crust form the lithosphere, which is divided into 7 large plates. Plates move because of convection currents in the mantle.
10. Explain plate tectonics theory. What is the main difference between continental drift and plate tectonics theory?The plate tectonics theory states that the plates interact in various ways producing earthquakes, mountains, volcanoes, and the like. The plates move very slowly at a rate of about 5cm per year! The main difference between the theories: (1) none of the plates is defined as a continent (2) the plates move along with the ocean floor (not through it as in Wegner’s theory of continental drift).
11. Complete the following table : NOTE: The total surface area of the Earth’s plates does not change, but each may grow/shrink in area
Boundary Type How do the plates move? What does it cause? Picture
Convergent
Together Volcanoes, some earthquakes (subduction zone: when one oceanic plate is forced beneath a 2nd plate, destructive)
Ocean-continent: volcanic island; Ocean-ocean: volcano; Continent-continent: mountain (neither plate sinks/can be subducted)
Divergent

2. What is the difference between saltwater and freshwater?Salt content
3. What are 2 major sources of freshwater?Glaciers, rivers, lakes, streams, etc.
4. Define the following: Evaporation – water heats up and changes state from liquid to gas (boiling pot of water) Condensation – water cools down and changes state from gas back to liquid (morning dew) Transpiration – evaporation off of a plant/leaf Precipitation – water in vapor form (gas) in clouds gets heavy, falls back to Earth as liquid (rain, snow,
sleet, hail) Runoff – water that hits the Earth’s surface and is not absorbed into the top layer of soil (flows down
slopes and into streams/rivers/lakes) Infiltration – water that hits the Earth’s surface and IS absorbed into the top layer of soil

Greenhouse Effect
Name: _______________________________ Freshwater1. According to the graph, what is happening to
CO2 levels and how does this affect temperature?
Co2 levels are rising over time (positive slope); Co2 is a greenhouse gas that traps the Sun’s (solar) energy, causing average global temperatures to rise (global warming).
2. What is the greenhouse effect?
The greenhouse effect is the process whereby carbon-containing gases such as carbon dioxide (CO2) and methane (CH4) trap Solar energy in
the atmosphere. This heat-trapping effect can cause global temperatures to rise.3. What are some greenhouse gases? What do they do? Where do they come from?
Carbon dioxide (CO2) and methane (CH4) – they are responsible for the greenhouse gas effect (above). They come from human and animal waste, humans and animals breathing, burning fossil fuels (such as gasoline in our cars).
4. What will happen to our Earth if we continue to put greenhouse gases into the environment?
If we continue to put greenhouse gases into the environment, the Earth’s average global temperature will continue to rise. This change in temperature can impact entire biomes/ecosystems. Thinking specifically of the tundra: ice caps/glaciers will continue to melt as global temperatures rise, which causes a rise in sea level. This will affect marine environments as well as coastal environments (some states/countries near sea level, for example, will sink)
5. How can we lower greenhouse gas emissions (and thus our carbon footprint)?
There are many correct answers; ex) use fewer fossil fuels or ones with fewer carbon emissions (natural gas), use less electricity (cut off lights/be conscious of everyday actions)
