100

This liquid space formed on earth 3.8 billion years ago.

What is Earth's Ocean?

100

This is the total amount of dissolved salts in water; grams pf salts per kg of water g/kg

What is Salinity?

100

This is the amount of Joules when freshwater is raised to 27 C from 25 C

What is 8,360 J?

100

This is where Hydrolysis can form in.

What is Insoluble Oxides or Hydroxides? 

100
0.61% of the Earth's Water comes from this place

What is Ground water?

200

This is the reason why colder water can be on top of warm water

What is density?

200

This makes up 55.1% or 19.35g/kg in seawater (S = 35)

What is Cl-?

200

This is used to get mizi squared.

What is Molarity x (Charge)^2?

200

This ion decreases as pH decreases.

What is OH-?

200

This Specific heat is 4.18.

What is pure water?

300

It takes 37,000 years to fill the ocean with this type of water.

What is river water?

300

This "made-up" unit to make salinity measured by conductivity proportional to g/L

What is PSU?

300

This is the amount of salt in solution when there is 0.4 g/Kg of sea water and assume the Calcium constant and salinity is used 

What is ~34 g salt per kilogram of seawater?

300

This happens to Iron 3+ as more water is added.

What is Lose charge? 

300
This is the second most common element found in the Earths crust.

What is Si?

400

Water molecules form this type of structure when frozen

What is lattice?

400

This allows tropical areas to have high salinity.

What is net evaporation? 

400

This is the ionic strength of (0.50 M) of Calcium Chloride

What is 1.50M? 

400

These are not included in equilibrium equations.

What is Solid or Liquid?

400

This is the Activity of Sodium when sodium is 1.7 x 10-4 M.

What is 1.3 x 10-4 

500

These are the reasons why 90 meters increase in SLR when earths ice caps melt is often an overestimation. 

Unique topography of the ocean and continental shelf is deeper 
500

Using this allows to determine the concentration of one major ion.

What is Marcets Principle? 

500

This is the Activity of Calcium when using Davies equation and an Ionic Strength of 1.0. Assume the molarity is 2.0 x 10 ^-5. 

What is Activity (i) = 7.8 x 10^-6?

500

This is the process in which more FeOH3 is dissolved in solution then Fe3+

What is "Salting in?"

500

This equation is used to account for different pH (rather the different activity of H+).

What is K*sp = [Ion] / [10^-pH / ActivityH] ^ Charge?
