It would be Approximately 24.5
Answer:
boron and carbon isotope, Phytane, Ice cores, Corals, Lake and ocean sediments etc.
Explanation:
- Drillings in ice cores like within ice sheets of Greenlands, Antarctica started in 1956. Collecting core samples of 4 and a half inches and use of molecules of water O 16 and 18 that helps to determine the past atmospheric carbon.
- Corals, skeletal rings have bands of paleo-climatological information and as their body is made of the calcium carbonates these limes creating organisms help to determine the atmospheric concentration of carbon on prehistoric earth.
- The use of oxygen isotope in lakes and oceans has given data related to the content of ocean sediments, and values deposited in clay and sand.
- The use of phytane a diterpenoid alkane that breaks down chlorophyll is used to estimate the ancient Co2 level.
The answer is B. The downhill flow of soil and rock resulting and rock
Mass movement is the movement of surface material caused by gravity ,
the downhill flow of soil is commonly known as landslide is a type of mass movement, so does the downhill flow of rock resulting from gravity ( commonly known as rockfall)
Answer:
It can be a transform boundary, convergent boundary, or divergent boundary.
Explanation:
Transform boundary
Explanation:
A transform plate boundary produces a strike slip fault.
A strike-slip fault is a type of fault in which two plates moves past one another in a linear form. This causes shearing of the two plate margins.
- This type of fault occurs in a transform margin.
- Along a transform margin, plates slides past one another.
- Transform margins are known for earthquake activities and some slight volcanism.
