To figure out just where that earthquake happened, you need to look at
your seismogram and you need to know what at least two other
seismographs recorded for the same earthquake. You will also need a map
of the world, a ruler, a pencil, and a compass for drawing circles on
the map.
Answer: The core produces heat in the center of the earth
Explanation:
Non - clastic sedimentary rocks are formed by precipitation of the minerals from the ocean water or from the breakdown of the bones and shells of sea species . Sea animals like the corals produces calcium carbonate solutions which solidifies to form rock .
Since the chemicals from the biological or mineral precipitation get mixed along with the sediments in the lake or ocean , which crystallize and grows , and finally forms a rock .
The correct answers are:
- Formation 2 is an intrusion;
- Formation 1 in an extrusion;
- Formations 1 and 2 are igneous rocks;
The formation one on this image is an extrusion, and the reason why it is an extrusion is that it has come out on the surface. The formation two on this image is an intrusion, and the reason why it is an intrusion is that it has formed deep into the ground.
Both of the formations will produce igneous rocks. The formation one will produce extrusive igneous rocks that will have very small crystals because of the quick cooling off of the magma. The formation two will produce intrusive igneous rocks that will have larger crystals because of the slower cooling off of the magma.
