- How does acid rain connect to the water cycle?
- Because wet deposition interfers with acid rain. Acid rain is formed by percipitation
- How is acid rain connected to the carbon cycle?
- Because NOx and SO2 is producted by combustion, therefore creating Acid Rain.
- What are the primary acids found in acid rain?
- NOx and SO2
- List three effects of acid rain?
-
1. Damage to building materials.
2. Acidification of lakes
3. Danger to human/animal health - Magma
- Molten rock beneath Earth's surface
- Lava
- Magma that has reached the Earth's surfance and erupted from a volcano
- Pyroclasts
- Large rock size fragments that erupt from volcanoes
- Vents
- Areas where magma reaches the Earth's surface
- Stratovolcano
- Tall, steep moutains made of layers of volcanic lava and ash
- Cinder Cone Volcanos
- Steep piles of loose pyroclasts
- Geothermal Energy
- Can cause geysers
- Balsaltic Magma
- Associated w. sheild volcanoes
- Stratovolcanoes typically occue at what type of boundary?
- Convergent Plate Boundaries
- Shield volcanoes have what type of magma?
- Basaltic magma
- Hawaiian volcanoes are an example of what type of volcano?
- Shield
- Stratovolcanoes are associated with what type of eruption?
- Quiet and Explosive
- Magma that is high in silica is ______
- Associated with explosive eruptions.
-
Convergent Boundary:
What happens to lithosphere? - Lithosphere is destroyed and mountains are formed
-
Divergent Boundary:
What happens to lithosphere? - New lithosphere is formed
-
Transform Boundary:
What is an example? - California
- Asthenosphere
- A layer of mantle that is composed to material that flows
- Epicenter
- Where seismic waves reach the earth's surface directly above focus
-
Focus:
How deep?
What about earthquake? - Up to 50kn deep where an earthquake begins
- Faunal Succession
- fossils can be used to identify the relative age of layers of a rock formation
- Lateral Continuity
- Sediment extends in all directions when it forms rock layers
- Superposition
- the bottom layer of rock is older than the top layer
-
Igneous:
How formed? - Formed from cooling molten rock
-
Metamorphic:
How formed? - Formed under intense heat or pressure
-
Sedimentary:
How formed? - Formed in layers from accumulated sediments
- Continental Drift
- the pieces of Pangea moved apart to form seven continents
- Earthquakes are most likely to occur with this plate boundary....
- Transform
- Earthquake is location is found by determining:
- the difference in arrival times between s and p waves
- Give an example of a mt. formed at continental-continental plate boundary...
- Mt. Everest
- Why is the earth like a giant recycling machine?
- when lithosphere plates are created at one boundary they are destroyed at another
- What types of currents drive the rock cycle?
- convection currents
- What causes hot spots?
- Caused by crustal plates moved over a hot plume in the mantle
- What three things are associated with divergent plate boundaries?
-
1. mid ocean ridge
2. sea floor spreading
3. new lithosphere forming - What is the name of the two land masses formed from Pangea breaking apart?
- Laurasia and Gondwanaland
- Density Formula
- D = M / V
- Mass Formula
- M = D x V
- Three phases of water in order from slowest to fastest.
- solid - liquid - gas
-
True or false?::
In the gas state, molecules move around freely. - True
- What are the three types of convergent boundaries?
-
Continental-continental
oceanic-oceanic
oceanic-continental
