Review Materials

Recommended review: p.384-387  (come see my teacher's book with the answers in it any time)
TGT review game
(look at older posts from this unit to review all of the notes too, as well as your own notes!)
Possible exam essay topics:
1. Describe why the asthenosphere “melts” as it comes to the surface of the Earth, and how this relates to the inner and outer core of the Earth.
2. Explain in detail the process used to locate the epicenters of earthquakes.  Why is it important to locate epicenters, especially if the earthquakes occur over water?
3.  Describe how volcanoes can form as a result of two types of plate boundaries.
4.  Describe different types of volcanoes, and the reasons they form different shapes and erupt differently.
5.  Relate the energy released within the Earth’s interior to movement of continents, explaining all processes involved and the regions within the Earth involved.
Learning Objectives for this unit:
1. Compare the densities of oceanic and continental crust using vocabulary (felsic, mafic, intermediate) and implications when they meet
2. Relate the densities of the materials found in continental and oceanic plates to the processes that result in each type of plate boundary (i.e., diverging, converging, transform)
3. Describe the internal source of energy on Earth that results in uneven heating of the mantle (i.e., decay of radioactive isotopes)
4. Illustrate and explain the convection currents that result from the uneven heating inside the mantle and cause movement of crustal plates
5. Describe how the energy of an earthquake travels as seismic waves and provides evidence for the layers of the geosphere
6. Describe the effects of the movement of crustal plates (earthquakes, seafloor spreading, mountain building, volcanic location on planet, hot spots)
7. Articulate the processes involved in the theory of Plate Tectonics (uneven heating of the mantle due to the decay of radioactive isotopes, mantle convection currents, movement of continental and oceanic plates along diverging, converging, or transform plate boundaries) and describe evidence that supports this theory (correlation of rock sequences, landforms, fossils, faults, evidence of seafloor spreading)
8.  Relate the concepts of thermal energy, convection, and pressure to the layers inside the Earth, and identify them.

Sig Fig notes, Friday agenda (In Library Computer Lab)

Friday, 3/28:
Work on either research for your presentation (see notes below), finish your sig figs WS and check the answers using the link below, practice Sig Figs using the two games linked below, or work on optional assignments from the past (links also below.

Significant Figures Notes (Started Wed)

Significant figures practice WS  (includes answers on second page)

Sig Figs game 1

Sig Figs game 2

Optional assignment: New Madrid Turns 200

Optional assignment: Tectonic Plate Simulation


Monday: (Optional) present what you have researched (on your own) about a topic concerning something following the themes of:
Groundwater - quality and quantity  (you can look into political viewpoints surrounding water too)
Caves and sinkholes
Mineral formation
Rock differentiation
Or be creative if you like with something not listed if you can relate it.  :)
~5 minute presentation (or more if you wish), with sources - may be multimedia like a prezi or slideshow, a poster, or just a lecture or sketches on the board.
Points will be counted as optional assignment points; will only help your grade.  The number of points will depend on the quality, difficulty, research, knowledge shared in the presentation, but I expect to range between 10 and 40 for most folks.

Optional Assignment, Plate Tectonics Review today

HMWK for Wednesday:  Read 608-615; p. 615#1-8

Optional Assignment:  Plate Tectonics Simulation

Due March 28.

Earth's interior Objectives from this unit:
1. Compare the densities of oceanic and continental crust using vocabulary (felsic, mafic, intermediate) and implications when they meet
2. Relate the densities of the materials found in continental and oceanic plates to the processes that result in each type of plate boundary (i.e., diverging, converging, transform)

Epicenter location WS today/Thursday, HMWK for Mon, Quiz Friday

earthquake epicenter WS
For the equation, you are welcome to use:  P-S delay times 7.5 km/s... this should give you a distance from the epicenter to the seismograph.  (a simplification of what we did in class)
We will be working with compasses in class tomorrow.

HMWK for Monday:  Read p. 370-378, p. 372# 1,2,5    and p. 378#1-8     The equation for volume of a sphere is 4/3 (pi) times radius cubed.  You will have to use some logic to solve the problem involving relative sizes of Earth's layers.

Also, Friday we will have a quiz on plate tectonics and Earth's interior concepts we've learned so far, and have a fun competition for the most tectonic plates memorized.

Notes on Friday afterward:  How we know what we know about the inside of the Earth.
