Answer:
Continental crust is about 20 to 70 km thick and thus 70% of this submerged and oceanic crust being about 10 km thick is only 30 % submerged.
Explanation:
- As the hydrological crust is considered to be much denser than the oceanic crust hence at the subduction zones the crusts sink into the mantel and are beneath the lighter continental crust as the oceanic crust is much older than the continental crust. As the continental crust forms many layers and has a bulk composition and the average density is about 2.83 g/cm and has a thickness of about 7 to 10 km.
I believed the answer is b
Race, ethnicity, and nationality allow people to connect and be classified. I dont know what your lesson is though.
Deserts are defined by the lack of precipitation, and in fact, Antarctica is also a desert - so we can reject the first and last option since they're not typical of Antarctica.
most deserts are characterized by drastic differences in temperatures: so the best answer is: c. a huge difference between minimum and maximum daily temperatures
Hey there! I'm happy to help!
The Fertile Crescent is basically where human civilization started. It stretches from Mesopotamia and across the Mediterranean coast to Egypt. Early civilizations depended on agriculture. To make agriculture, you need a river because it is a good water source to help grow your crops.
If you look at the map I have provided below, you will see that there are tons of rivers. This would make it very easy for settlers to grow crops. This means that sea tides and eroding mountains aren't the answer. I don't think the rivers were flooding and natural canals is an oxymoron because canals are artificial waterways, but this all should give you and idea.
Have a wonderful day! :D
