Metamorphic rocks are formed from other rock that has been subjected to very high temperature and pressure.
When one of the earth's plates comes in contact with another either by both traveling opposite directions, straight into each other, or from one slipping under the other (subduction zone), the pressure/friction of the plates against each other melts the rocks and after they cool they are metamorphic. Example is in Washington state when the Juan de fuca plate is going under the North American plate the pressure/friction of this melts the rocks which then form metmorphic rock.
Alcohol
may positively affect the cardiovascular system of people over 50 years old by
reducing the risk of clot formation.
<span>Just like with the other body systems, excessive alcohol can have lethal
effects on the cardiovascular system. Chronic alcohol use can upsurge the
workload of the heart which can then lead to arrhythmia's or what is called an irregular
heart beat, inflammation of the heart muscle or myocarditis, weakening of the
heart muscle or cardiomyopathy, increased cholesterol, and even hypertension.
Other problems are prominent with blood clotting and an increased workload of
the heart that is linked to cirrhosis of the liver.</span>
Data tables help us understand information by comparing and contrasting it with visual proof. Sorry, that's all I could come up with.
Rocks? not quite sure about this one but good luck and hope this helps! :)
Answer:
They are clastic sedimentary rocks
Explanation:
Sandstones, siltstones and shales are all clastic sedimentary rocks.
Clasitc sedimentary rocks are derived from other rock types.
These rock types typically forms from the suspended and bed load of erosion. The weathering of rocks provides the materials that forms these rock types.
The difference between the three rock types is based on their size. Shales are the finest while sandstones are made up of sandsized particles. Siltstones are in the middle.
