[Minerals] Let us look at silicates in a little more detail. Depending on a silicate mineral’s composition, the Si-O tetrahedra that make up the mineral will arrange themselves in different patterns. Drag the silicate framework name to the correct schematic on the image provided.

[From Big Bang to Blue Marble] Which of the following best explains why terrestrial planets formed closer to the Sun, while gas giants formed farther away?

[Tornadoes, Thunderstorms & Hurricanes] The map below shows the number of tornadoes per year (per 26,000 square km, for a 27-year period). Order the cities listed below based on the likelihood of their experiencing a tornado over the course of a year. Start with the least likely.

[From Big Bang to Blue Marble] Which of the following statements accurately describe processes or outcomes related to the condensation theory and Earth’s differentiation? (Select all that apply.)

[From Big Bang to Blue Marble] Which of the following scenarios best illustrates the difference between contact and field forces?

[From Big Bang to Blue Marble] A geologist discovers a solid material with an unordered atomic arrangement that formed from rapid cooling of molten rock. Which material classification is most accurate?

[Tornadoes, Thunderstorms & Hurricanes] Thunderstorms have long fascinated humans. The sensory stimulation of light and sound causes people to feel a range of emotions from exhilaration to fear. In this Exploration we will explore thunderstorms, how they form, and what can trigger the most violent of localized storms: the tornado. Thunderstorms require several “ingredients” to form. Which of the following environmental conditions will help lead to thunderstorm formation?

[Tornadoes, Thunderstorms & Hurricanes] Supercell thunderstorms can give rise to tornadoes. The image below shows an annotated radar image of a supercell. Identify the main downdraft and updraft locations as well as the likely location of tornado formation.  

[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?  

[Tornadoes, Thunderstorms & Hurricanes] In April, you see this supercell making its way northeast across northern Alabama. Based on the general shape of the supercell, which town is located within the forward-flank downdraft? Click on the correct town on the map.
