Answer:
oceanic crust sinks because it is denser and has higher specific gravity than the more silicon aluminum enriched continental crust. What drives substitution is convection and conduction in outer core of earth, that heat , only a small part of which is due radioactive isotopes, has to make it's way to Earth's surface by both conduction and convection. Iron and nickel o have the highest specific gravities of the 10 most common elements in the Milky Way Galaxy. This is why oceanic crust sinks and is subducted continental crust has to have a lot more force applied before it inks, because it doesn't want to sink.
Answer: Its presence is a good determinant of past hot climates. Its absence can also indicate cold climates.
Explanation:
18O and 16O are oxygen Isotopes, and are used in determining past climates. Heavier than the 16O with 10 neutrons and 8 protons, the 18O does not evaporate as easily and because of this, higher amounts are found in the tropics.
Together, they serve as good determinants of past climate by checking for their ratio in fossils.
Also the 18O isotopes are not present in polar regions as they precipitate before getting to higher altitudes. Cold areas, on the other hand, are high in 16O as they get trapped in glaciers. When climate changes in a location, the quantity of both of these oxygen isotopes also changes.
Explanation:
The Ottoman Empire was the largest Empires in history.
Muslim Turks created the Ottoman Empire and it became a very powerful states
It was an empire motivated and supported by Islam and by the Islamic institutions.
Ottoman Empire was a superpower that existed for six hundred thirty-four years and it was the largest empires to govern the boundaries of the Mediterranean Sea.
Answer:
foresters and conservation scientists, forest and conservation technicians, forest and conservation workers and loggers.
Explanation:
Conservation scientists and foresters evaluate data on forest and soil quality, assessing damage to trees and forest lands caused by fires and logging activities. Forest conservation technicians assist foresters and scientists in protecting the animal and plant life in forests. They may also participate in forest nursery or logging operations. Forest and conservation workers perform basic tasks to maintain and improve the quality of the forest.
