Explanation:
Answer:
if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)
Explanation:
The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.
Litostatic pressure originates from the weight of materials in the interior of the crust.
Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.
There are different types of metamorphism.
Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.
Classification of the metamorphic rocks according to their structure:
- Granulation
- Recrystallization
- Metasomatism
- Massive
- Foliation
Foliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.
<em>According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation. </em>
Answer:
Profase I
Explanation:
La Profase I es la primera etapa de la meiosis en la cual el material genético se condensa para formar los cromosomas y se desarrolla el huso acromático (huso meiótico). El entrecruzamiento, también conocido como sobrecruzamiento o <em>crossing-over</em> (por su nombre en inglés), es un proceso que consiste en el intercambio de material genético entre cromátidas no hermanas de cromosomas homólogos. El entrecruzamiento se produce durante la Profase I, es decir, durante el período inicial del primer ciclo celular meiótico (meiosis I). El sobrecruzamiento tiene una importancia fudamental desde el punta de vista evolutivo ya que este fenómeno incrementa la diversidad genética de las gametas obtenidas mediante este proceso.
