[From Big Bang to Blue Marble] Which statement best explains why igneous, sedimentary, and metamorphic rocks are considered distinct categories?

[Tornadoes, Thunderstorms & Hurricanes] Over the week you watch the storm build into a Category 5 storm before weakening to a Category 3 as it comes ashore. Where on the shoreline would the storm surge be the strongest?

[Plate Tectonics] Based on the direction of plate motion you just determined in the previous question;  where would you expect the next large eruption to occur?

[From Big Bang to Blue Marble] Which of the following statements accurately describe the thermal and pressure conditions inside the Earth? (Select all that apply.)

[Stellar Evolution] Using the three scales again, classify a class M star, like Betelgeuse.

[Planetary Geology] Finally, let’s look at a more complex assortment of craters. Here we can see four craters clustered together. Based on the principle of cross-cutting relationships, you should be able to place the craters in order from oldest to youngest.

[Tornadoes, Thunderstorms & Hurricanes] Thunderstorms thrive in unstable atmospheric conditions. Thunderstorms are less likely to form under stable atmospheric conditions. The image below shows the troposphere under stable conditions. Click on the layer of the troposphere that will experience the highest atmospheric density.

[Tornadoes, Thunderstorms & Hurricanes] What type of lifting would likely be responsible for the squall line (the narrow band of thunderstorms running northeast to southwest) seen in the following image?  

[Climate Change] Watch the animation below to explore the primary causes of sea-level change. Select “Topics” to see the video options. Click here to open the interactive animation in a new window. From the video, you can see that melting ice, plate tectonics, volcanism, and thermal expansion all drive sea-level change. Some of these causes are present regardless of temperature fluctuations. Others are directly affected by increases or decreases in temperature. From the choices below, select the temperature-dependent drivers of sea-level rise.

[Planetary Geology] There are more than just planets within our Solar System. Match each term with its definition.
