The subduction zones

Melting around subduction zones occurs because the sinking plate causes the asthenosphere to rise and melt due to decompression melting. Discuss

The Brazos River

Describe the difference in the color of the water at this stop with that at the Brazos River. Why is the water on the beach not blue? How many colors of shells can be recognized on the beach? From which geologic age do they come?

The sediment with high porosity and permeability

Describe the following two situations: (1) sediment with high porosity and permeability; (2) rocks with low porosity but high permeability. Give an example of a geologic material associated with both situations.

The thermal stratification of water layers

Explain how the thermal stratification of water layers affects the availability of resources that algae need. Related to that, explain how light and nutrient availability to algae changes over the course of a year in lakes in Michigan

The James Webb Space Telescope

The James Webb Space Telescope image of Neptune shown above was taken using the NIRCam instrument, which creates images using light with wavelengths between 0.6 and 5 microns. That spans a little bit of yellow and red visible light (0.6 microns to about 0.8 microns) but is mostly “near” infrared (up to 5 microns). What is the frequency of light that has a wavelength of 4.00 microns?

The accretion of nebular dust

Which is more likely to have formed the current atmosphere: accretion of nebular dust or volcanic outgassing? explain

The elevation of the water table

Does the level of the water in a well always correspond with the elevation of the water table? Hint: Think about the level of water in a well drilled into a confined aquifer. Discuss

The typical spectrum of a planet

Describe the features seen in a typical spectrum of a planet in our solar system. What features are seen at ultraviolet, visible and infrared wavelengths?

The processes of photosynthesis and cellular respiration

 Briefly explain the overall processes of photosynthesis and cellular respiration. Include a brief explanation of autotrophs and heterotrophs in your answer.

The terrestrial and Jovian planets

Briefly described the characteristics of both Terrestrial and Jovian planets that are different from each other. (You will have four facts in total.) Explain your choices.
