Answer:
Phosphorus cycle
Explanation:
Biogeochemical cycle, any of the natural pathways by which essential elements of living matter are circlated.
There are four types of biogeochemical cycle, they are ; water cycle,carbon cycle,nitrogen cycle and phosphorous cycle
Carbon cycle is the cycle in which photosynthesis and cellular respiration take place.
Water cycle involves transpiration.
Nitrogen cycle Is the cycle that is dependent upon bacteria for nitrogen fixation and denitrification.
Phosphorus cycle is one of the slowest biogeochemical cycle. It does not stay in the atmosphere, because it is normally in a liquid state at room temperature. It does not include the atmosphere.
A tree getting struck by lightning, it is an example of a physical change.
It is so because when a tree getting struck by lightning, it encountered a strong force of power but no new substance is formed here. So it is a physical change, if it is a chemical change then a new substance must formed here. So when a tree getting struck by lightning, it is an example of a physical change.
A tree getting struck by lightning involves both physical and chemical changes but the most prominent change is physical due to the visible damage and the instant vaporization of the tree's sap.
When a tree is struck by lightning, both physical and chemical changes occur. The lightning's immense heat can cause the sap inside the tree to instantly turn into vapor which results in a physical change. Additionally due to the lightning's high temperature, some of the tree's matter could possibly undergo chemical reactions such as combustion, leading to new matter being produced, which is a chemical change.
However the most prominent change observed is physical, as the visible damage to the tree and the immediate change from solid to vapour state of the sap are the most noticable effects. Thus, in essence a tree getting struck by lightning mainly causes a physical change.

Answer: The correct representation of the element with 15 electrons and 16 neutrons is phosphorus (P).
Explanation:
hexagonal
triclinic
cubic
Answer : The correct option is, Cubic.
Explanation :
As there are seven types of crystal systems which are cubic, tetragonal, orthorhombic, monoclinic, triclinic, rhombohedral and hexagonal.
A unit cell is characterized by the axial length (a, b and c) and axial angle parameters which decide the size and shape of the unit cell.
In tetragonal crystal system, and
In hexagonal crystal system, and
In triclinic crystal system, and
In cubic crystal system, and
Hence, the correct option is, Cubic.
Answer:
Explanation:
_Andesitic__ magma is a mix between basaltic and rhyolitic magma. The eruption that would most likely result from this magma is a _strombolian____ eruption.
Andesitic magma straddles between basaltic and rhyolitic magma. They produce rocks that shows both basaltic and rhyolitic affinity. Examples of rocks that results from this type of magma is andesite.
Strombolian eruptions results from this type of magma. They are charactised by moderate to low bursts of magma. Their explosivity is between 2 and 3.
