What we learned about Earth

HI every body I decided to share about what I learned this week in science classe:

The hope diamonde

The hope diamond necklace was cute from a stone of 240 carats.TH necklace was originally 75 carat but they changed it to 67.89 for better proportion. The necklace was design by Baumgold Brother. The total weight of the 106 diamonds is 45 carats It was worn during the movie Tarzan’s savage fury

Earths STRUCTURE

Earth’s crust is mainly compose of 2 type of rocks Basalt and Granite

The mantle: about 84 percent of Earth’s volume is mantle rock. IT flows like a glacier do

The outer core is molten and so hot it could be a fluid as water it is such a immense pressure that it is like a metal

1959, the Hawaiian volcano Kilauea produced rivers of red-hot lava that filled the adjacent crater, Kilauea Iki, to a depth of 135 m (440 ft) and created a lake of molten rock

GEMS
About 15 different minerals are commonly used for gemstones. The biggest gem producing countries are: Tanzania, Madagascar, South Africa , Australia…. A last thing to Know is that Gems are made of fluid, heat, and pressure.
