question 1
Pangaea is evidence that the plates have moved. It was all once together but over billions of years they have sperated. I found it in the science book in the section about plates. these plates are the lithospheric plates. The boundaries are divergent convergent and transform. Mid ocean ridges mark divergent boundaries. Volcanoes form near volcanoes. Transform is a place where two plates past each other.
volcano
magma forms under the ground and it comes out of whats called a volcano.
tsunami
plates make a big wave called a tsunami.
tornado
a mixture of heat and strong waves make a tornado.
breaking up sedimentary rock
question 5
Erosion is a destructive process in which water or wind loosens and carries away fragments of rock. The three types of erosion are running water winds ice. running water is the worst while ice is has the least power.
fossils
law of superstition
is a key axiom based on observation of natural history that is a foundation principle of sedimentary is called the law of superstition.
fossils
this picture shows that there are different types of fossils not just one type. We have dinosaur fossils, plant fossils, and mammals.
fossils from the past
by studying fossils they can tell us how long life has lived on earth
rocks in the ground
igneous rock
this is an igneous rock. They are formed from heat and pressure.
sedimentary rock
This is a sedimentary rock. It is formed when ice or water breaks it up into rock form.
metamorphic rock
This is a metamorphic rock. they could have been igneous but they morphed into a sedimentary rock
rock cycle
the rock cycle makes lots of changes. An igneous rock can change into a sedimentary rock or a metamorphic. A metamorphic rock can change into a igneous or a sedimentary rock. All of the different types of rocks can turn into all of the other ones.
daimond
The way they form is they get crushing pressures and extreme heat. We can Identify them using the hardness test.
what i liked
I liked how we learned about volcanoes. Also i liked playing that mineral game
