No the law of cross cutting relates to all somewhat horizontal. The law of cross cutting is the logical assumption that a magma protrusion that cuts through horizontal layers at a diagonal or vertical is younger than the layers that it cuts through.
Sedimentary rocks are most often found in horizontal or near horizontal layers or strata. Therefore cross cutting can be used most often in the relative dating of sedimentary rocks.
However lava flows also form horizontal layers of rock. Pumice ash can be laid down in horizontal layers. A magma protrusion can also be used to relative date igneous layers of rock
Answer:
147,558,601 sqkm
Explanation:
The earth is spherical in shape;
area of sphere = 4πr²
if 70.8% is covered by water then 100-70.8 will be land,
= 29.2%
area occupied by land = (29.2/100) * 4πr²
= 0.292*4*3.142*(6371)²
=147,558,601 sqkm
Explanation:
1 grams Ammonia to mol = 0.05872 mol
mass of ammonia = 2.75÷ 0.05872
mass of ammonia=46.8324250681 gm
Answer:
The symbol that represent a salt is CaCl2
Explanation:
The CaCI2 is the calcium chloride that an organic compound now a salt having a chemical formula i.e. CaCI2. Also it is non-color cyrstalline solid at the room temperature also it is highly soluble in the water
Therefore as per the given situation the symbol that represent a salt is CaCI2
