1. What is the general term applied to sediments deposited by turbidity flows, and what bedding does it show?
2. What is the difference between a mid ocean ridge and a mid ocean rise?
3. What is longshore drift and why does it occur?
1. abyssal fan, im not sure what your looking for but maybe steep slopes and active continental margins.
2. nothing? i looked it up and it said they were synonyms...
3. longshore drift is the zigzag movement of sand down a beach in the direction of longshore currents that hit the beach at and angle and come back straight due to gravity->zigzag.

I think #1 may have been turbidites, which show grades bedding. This is sort of a geomaps thing but I think fair game for dp.

Umaroth was right about 1, you were spot on on #3. From what I learned, ridges are steeper with slow spreading rates (1-5 centimeters per year) - Example: Mid-Atlantic Ridge, and rises are flatter with fast spreading rates (greater than 9 centimeters per year) - Example: East Pacific Rise.

ooooh okay!

1. what are some key differences between summer and winter beaches?
2. what is the difference between an emerging and submerging shoreline?
3. what feature of erosion is uplifted to form a marine terrace?

1. Summer beaches have a wide berm, while winter beaches have no berm. Also, in a winter beach, sand is transported out to bars, which does not happen with summer beaches. 2. Emerging is when either the shore raises from rebound or the sea level decreases so more shore is exposed. Submerging is when sea level rise, showing less shoreline. 3. According to a test I recently took, wave-cut platforms?

1. correct! altho there are some other differences too, mainly that winter beaches have heavy wave activity
2. yep!
3. correct :)

1. What three main factors contribute to the energy of a wind-generated wave?

2. What is a sverdrup?

3. What is tritium and what is it used for?

1. fetch, wind speed, wind duration
2. a rate of the amount of water movement
3. idrk but im guessing its an element that can be used to trace water masses.

1) Correct.
2) More specifically equivalent to 1*10^6 m^3/s.
3) Tritium is a radioactive isotope of hydrogen with 2 neutrons. I'm pretty sure it would be used for tracing like you've said.
