Kepler = the scientist who discovered that the orbits of planets are elliptical rather than circular

Ptolemy = the scientist who revised the geocentric model of the solar system to account for retrograde motions of some planets

Copernican Revolution = geocentric model, shift from an Earth-centered to a sun-centered model of the solar system

4.9 Our Solar System Topic Test
Kepler's Laws
QUESTION 14:  The cube of the orbital radius is proportional to the square of the period for any orbiting body. 
ANSWER: Kepler's 3rd Law

QUESTION 15: A planet speeds up as it gets closer to the Sun, and slows down as it moves farther away. 

ANSWER: Kepler's 2nd Law

QUESTION 16: An orbit is in the shape of a slightly flattened circle or ellipse.

ANSWER: Kepler's 1st Law

QUESTION 17: For every action force, there is an equal and opposite reaction force. 

ANSWER: None of Kepler's Laws.

(This is actually Newton's 3rd Law of Motion)

Question 4 - The moon and the earth are very similar in composition–this means the makeup of the two are similar; however, the moon and earth are NOT similar in regard to atmosphere. The moon is 4.5 billion years old, was formed around the same time as the earth and is about the size of mercury.

Assignment 5.3 Earth’s Structure
Question 5 - Read the linked article to find out the author's prediction about the future of Earth's mantle. Write your answer in complete sentences with detail including whether or not you support this prediction.

Assignment 5.4 Geologic Time Scale
Question 1 - Use the information below the question in the next to last paragraph.

Questions 10, 11, and 12 - Use the information from the video.

More about Question 10 - Pause the video at time 1:23 to find the answer to this question. The Geologic Time Scale is also linked on this post for easier viewing.

Question 13 - Read the content ABOVE the video.

Questions 14-19 – Use the information in the video.

Assignment 5.6 Stories from the Fossil Record

Question 4 - The correct answer is False.  When viewing rock layers, the youngest fossils are on top.

Question 5 - The correct answer is False.  Fossils can and do tell us about past environmental conditions.  Using fossils, we can see how organisms have changed over time to allow them to better adapt to their environment.  

Question 7 How to work this problem:

t= [ln (25/100) / (-0.693)] x 5,000,000

t=  [ln 0.25 / -0.693] x 5,000,000

t= [-1.4 / -0.693] x 5,000,000

t= 2.02 x 5,000,000

t= 10,100,000 years

Question 8 How to work this problem:
t= [ln (40/100) / (-0.693)] x 5,730

t=  [ln 0.4 / -0.693] x 5,730

t= [-0.9 / -0.693] x 5,730

t= 1.3 x 5,730

t= 7,449 years

Question 1- Earthquakes create three types of seismic waves: (Primary (P), Secondary (S), and Surface). Seismic waves cause earthquakes.

Question 3- The most intense earthquakes happen at subduction zones.

Question 5 - Earthquake waves are detected and recorded with a seismometer.  The intensity of an earthquake is measured on the Moment Magnitude Scale, also known as the Richter Scale.

7.6 Natural Hazards:
Part 1: Read the information about Natural Disasters and any other research you can find on this topic to explain how natural hazards and other geologic events have shaped the course of human history.  14 points

Part 2: Follow up your original post by responding to two student posts anywhere in any thread. (3 points per thoughtful response).

Question 3: In the video it says "Most of Earth is made of igneous rock." At 0:40 seconds it also says "Over 75% of Earth’s land is covered by sedimentary rocks." The correct answer is sedimentary rocks.

8.3 Rocks:
Question 3: Discuss the damage to the White House and what was done to fix it to earn full points.

Question 4: 

Question 5 - The correct answer is "all of these"

9.5 Wind Erosion
Question 3 - What is needed for a sand dune to form? Answer: Plenty of Sand

Describe a specific hazard and a design solution to reduce its impact on human activities. Be sure to respond to 2 classmates with thoughtful complete sentences.

9.14 Geology Topic Test
Questions 22-25 - Type an answer into the text box using one of the following terms: crystals, sedimentary rock, igneous rock, extrusive igneous rock, metamorphic rock, magma, sediment
