In the above case, rock L and rock F does not undergo contact metamorphism because the rock unit F was only deposited after the intrusion of the rock layer L.  

Explanation:

Contact metamorphism rocks are formed as a result of static thermal metamorphism and high temperature at regions adjacent to hot intrusive igneous rocks within the metamorphic zone called the contact aureole. This takes place either through heat contact or contact alternation metamorphism. When the hot molten magma reaches an already formed rock body, the older rock body will undergo changes due to hot magma infiltration.

In the above case, rock I does not undergo contact metamorphism because the rock unit F deposited earlier in the process.  

The contact metamorphism can occur only within a small radius ( mostly 1-10 km) of the contact aureole which is heated by the hot magma. The heat should be sufficient enough to break the adjacent rocks and change their structure.  The timing of formation of both rocks is also a gradient deciding contact metamorphism between both rocks.

Why does diversity increase as height above land increases​
wolverine [178]

Biodiversity rises with altitude initially before falling with height beyond that. Up until it reaches a diversity peak at about 1 300 to 1 800 m.

  • The biodiversity increases at higher geographical locations because There are more hiding locations. They are better for crop growth. They frequently include more than one kind of habitat.
  • As latitude or altitude change, so does biodiversity. As we descend from high to low elevations, the diversity increases (i.e., from poles to equator).
  • While the environment is harsh and plants have a brief growing season in the temperate region, tropical rain forests provide year-round growth-friendly circumstances.
  • This enables the emergence and expansion of several species. On a mountain, there is an initial increase in species diversity after which there is a decline in species variety as you go up in elevation.
  • At higher elevations, temperature drops and seasonal variations increase, which significantly diminishes.

enyata [817]
When you aren't showering as regularly, your skin can become oily and salty leading to blemishes and breakouts. Although your skin can get all sweaty during the day anyway, not bathing means these bacteria are not being thoroughly removed or cleaned.

Explain the process of homeostasis through BOTH negative and positive feedback
kotegsom [21]
Homeostasis is maintained by negative feedback loops within the organism. In contrast, positive feedback loops push the organism further out of homeostasis, but may be necessary for life to occur. Homeostasis is controlled by the nervous and endocrine systems in mammals.
