Answer:
There is overwhelming evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth's atmosphere, ocean.
When sedimentary rock go to the bottom of a seafloor it sticks together over time and turns into metamorphic rock. Then metamorphic rock melts and when it cools down it turns into igneous rock. This process happen over and over and its called rock cycle.
<span>Answer:
The carbons on the closures are sp² hybridized, with a p-orbital for the 'second' bond in the twofold bond with their neighboring carbons.
They have those sp² orbitals covering with the s from the hydrogen, and they have a p covering in the pi bond with the neighboring carbon. They likewise have a sigma bond with the neighboring carbon I'll get to.
The center carbons each have two pi bonds with their neighbors, leaving sp hybridiaztion for the rest. So they have sp/sp² with the end carbons, and sp/sp with each other. (What's more, they likewise have p/p in the pi bonds).
So the total list is:
s/sp²
p/p
sp/sp²
sp/sp</span>
I wasnt sure at first, but now that i see the hint: BI......Your answer is Bilingual
Answer:
False.
Explanation:
Regional metamorphism is a common type of metamorphism involving the effects and cooperation of directed pressures and shearing stress as well as a wide range of confining pressures and temperatures. The heat element facilitates recrystallisation; but the stress element not only promotes recrystallisation, but is powerful in deforming the rocks, and producing new structures.
It is related both geographically and genetically to large orogenic belts, and hence is regional in character.
Regional metamorphism does NOT produce nonfoliated metamorphic rocks in the depths of mountain ranges. Regional metamorphism takes place at deeper regions of the crust and is, as the name already signifies, of regional extent. The different types of regional metamorphism, or still dynamothermal metamorphism, are confined to areas of mountain building, so that metamorphism as well as orogenesis ought to be regarded as due to one and the same process.
