Whew that was a long day, we
just got back from Mount Longonot and we had to drive for 74 miles in a bus.
Let me tell you, if you ever travel to Africa makes sure there is air
conditioning on the bus and you have water. While at the mountain we also saw
many animals roaming around. Here are just a few facts about Mount Longonot:
-Elevation
is 9,111 ft.
-Last
eruption around 1863
-The name Longonot originates from the Masaai word
Oloonong'ot, meaning "mountain of steep ridges"
Traveling
to Mount Longonot made it a lot more fun to learn about the African tectonic
plate which covers Africa. Interestingly the plate is about the same shape as
Africa it just extends farther. It moves about 2.15 cm each year for about the
past 100 million years towards the northeast direction. This plate is
surrounded by many other plates (North American, Arabian, Indo-Australian,
Eurasian, Anatolian and Antarctic plate), most of them having a divergent
boundary.
A
divergent boundary is one of the three main types of plate boundaries, also
known as a rift boundary or a spreading boundary. This is when two parts of the
outer earth move apart. Sometimes when something called se-floor spreading
happens molten rock cools and forms a new oceanic crust. As the crust gets
older the rift valleys (valleys that in the center of the mid-ocean ridge) move
away from the mid-ocean ridge.
Something
interesting I learned about earthquakes and volcanoes, is that you are able to
tell where the plate boundaries are by the locations of where there have been
earthquakes and volcanic eruptions.
This occurs when two plates push towards
each other, pull away or slide past each other. There is strain and it soon
becomes too great, so fractures form which creates earthquakes. High heat flows
through these boundaries and molten rock moves towards the surface which causes
volcanic action.
Well I have one more day until I leave for the next country, but I have to check my plane ticket to find out my destination. Hope you are
learning
some things, I sure am. See you in the next place.
