my great, great grandma's birthday
If the event or change has a great impact on the time period or is a great acomplishment for mankind somehow.
They were great! People enjoy talking a learning about this great event.
the great depression
The event is called Black Tuesday
Greate Oxygenation Event, This dramatically caused a new ice age because of the increase effecting the atmosphere.
There was an event commonly known as the "Great Oxygenation Event" which occurred around 2.4 billion years ago. One theory suggests that this was caused due to the production of oxygen by micro organisms. In the early Earth this oxygen normally reacted with minerals in the surface rocks during weathering (creating very thick beds of oxidised rocks such as banded iron formations). However a point was reached where no more minerals were available to react with the oxygen and so it began to accumulate in the atmosphere. Please see the related link for more information.
The event of Ivan the great is that he is great and he is a good inventor
This event is a great funraiser.
Oxygenation occurs in the placenta. After this blood then returns to the fetus via the umbilical vein.
Oxidation is loss of electrons to more elctronegative group where as oxygenation is carrying of oxygen molecules
The amount of oxygen in the atmosphere increased because the number of photosynthetic organisms, which release oxygen, on the earth dramatically increased. This lead to the Great Oxygenation Event, or the Oxygen Crisis, 2.4 billion years ago - when this free O2 entered the Earth's atmosphere.
The event was so fun and great.
You can find a great event planner on the site Business Know How. They have great information.

non-oxygenation
No. Oxidation is a redox reaction that characterizes a loss of electrons whereas Oxygenation is the addition of oxygen molecules.
