A time in which sea level reached a slightly higher level than today's, coinciding with the warmest period of the past 10,000 years with temperatures about 2 degrees celsius higher than today. Scientists have done further research and have predicted high rates of future sea levels.

The plow or plough is one of the most important tools for farming and is typically used to turn and break up soil, to help control weeds, and to bury crop residues. Several modern versions of the plow have been invented since then.

In 2005, Mike Brown and his team discovered an object further out Pluto's orbit & was later known as "Eris". Eris was discovered to carry more mass than Pluto. Debates on whether or not Eris & Pluto were planets erupted & it would later be decided at the XXVIth General Assembly of the IAU. The requirements made by the IAU:
- It needs to be in orbit around the Sun.
- It needs to have enough gravity to pull itself into a spherical shape.
- It needs to have "cleared the neighborhood" of its orbit -
The earthquake started at 2:46 PM and was later followed by tsunami waves less than an hour after the incident. More than 18,000 people were killed in this travesty, likely by drowning. The tsunami caused a cooling system failure which resulted in a level 7 nuclear meltdown and release of radioactive materials.
