Answer:
Metamorphic rocks (from the Greek meta, change, and morphe, form, "change of shape") result from the transformation of pre-existing rocks that have undergone structural and mineralogical adjustments under certain physical or chemical conditions, or a combination of both, such as the temperature, pressure and / or chemical activity of the fluids agents of metamorphism These adjustments, imposed exclusively under the surface, transform the original rock without losing its solid state, generating a metamorphic rock. The rock generated depends on the composition and texture of the original rock, the agents of metamorphism, as well as the time in which the original rock was subjected to the effects of the so-called metamorphic process. Due to the nature of their origin, there may be a complete gradation between metamorphic rocks and the igneous or sedimentary rocks from which they were formed. The study of these rocks provides very valuable information about the geological events that occurred within the Earth and about their variation through time.
Explanation:
To classify a metamorphic rock, the type of metamorphism involved must be known, which can be variable since it depends on the criteria that are taken as a basis to differentiate it: it can be classified from the point of view of extension, fit and cause , geological value, increase or decrease in temperature, etc., but it is very common to define three main types of metamorphism according to the predominant metamorphic agent: Regional, Contact and Dynamic.
hope my answer helped you
Answer:
0.15
Explanation:
Slope (m) =
ΔY
ΔX
=
-3
20
= -0.15
θ =
arctan( ΔY ) + 360°
ΔX
= 351.46923439005°
ΔX = 3 – -17 = 20
ΔY = -10 – -7 = -3
Distance (d) = √ΔX2 + ΔY2 = √409 = 20.223748416157
Answer: people decide to take wood and resouces from the rainforest unstead of thinking about sustainable development which is the process of being able to take things from the enviroment without damaging the ecosystems and ruining animals habitats.
Once again i hoped this help XD
Answer:
As Snail is a land species, they for about 2-3 years, based on there calcium carbonate shells it can be concluded that they form in tropics.
Explanation:
- When looking at the slabs or the plate from both the clockwise and counterclockwise, spiraled snails fossils are usually in the spiral forms and the bedrocks that may have collected their imprints from the sediments deposited in the geologic formation of the earth.
- The slabs of rock are hence evidence of the tropical climates and their creation is a due result of their shells that were deposited in the large tract of rocks when the uplifting of landmasses and the volcanic events take place.
- Geologists use carbon-14 dating technology of the rocks estimate that their formation which hence is impacted due to the climatic region dominating the tropical oceans and lands is suited to the formation of these small creatures that their existence on the calcium carbonates creates this evidence.
Answer:
B. France
Explanation:
The Vietnam war was fought between November, 1955 till April 1975. It was a war fought between North and South Vietnam. North Vietnam had allies such as China, and the Soviet Union. These countries were communist countries at the time the war was fought. South Vietnam had the support of the United States, Australia, South Korea, and the Philippines. These countries were against communism.
So, basically, the war was a result of rivalry between communist North Vietnam and non-communist South Vietnam. France at the time of the war was more of an anti-communist country.
