Answer:
more than 100000
Explanation:
I guess so cause In each plant there should be 1000 so if we calculate the whole and each states continents it should maybe be 10000 I am not sure about it I just guessed it
C, take hundreds of millions of years to form!
Dr luceros team used looters trenches rather than dig new ones because they wanted to protect the site from further damage. This is because to prevent further destructions from their activity.
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.
Answer:
dynamothermal metamorphism can break down the structures of their constituent minerals, but the minerals are unstable in that metamorphic environment.
