Weathering and Erosion

weathering

Physical or chemical disaggregation of rocks into smaller particles

• physical weathering accounts for roughly \(5.6 \times 10^{15}\) g/yr; more frequent in cold, arid environments
• chemical weathering accounts roughly for \(4.0 \times 10^{15}\) g/yr; more frequent in warm-tropical environments

type of weathering

• physical weathering

  pounding a rock disaggregates it into smaller pieces. breakdown the rock into sediment without changing chemical composition.

  • water limited environments (“stuff is dry”)
  • sites of significant relief

  • fire and freeze-thaw

Sedimentary Rocks

“Any loose, solid particle that may become entrained by a fluid.”

sedimentary rock

• sediment: any loose, solid particle / grain
• sedimentary rock: rock composed of sediment grains

types of sedimentary

detritus

Results of physical weathering

• detritus particles: water / ice / wind
• results in sediment

silicilastics

chemical weathering; non-congruent weathering

• clays
• resistant silicates (quartz, zircon)

carbonates

“precipitate”

carbonates results in congruent dissolution (fully weathered)

Stratigraphy

Each layer of deposit.

I’m currently making GPUs go brrr at SISL advised by Mykel Kochenderfer and StanfordNLP working with Chris Manning. I’m also a research software engineer at TalkBank lead by Brian MacWhinney. I’m visiting Microsoft Research Frontiers as a research scientist.

I don’t really have a good answer of what I work on and lowkey its kind of jit compiled based on what part of NLP or RL I happen to be thinking about. (Some) current threads include…
