What type of rock does preexisting rock become

Answers

Metamorphic rock is a type of rock that the preexisting rock becomes a new rock.
Metamorphism has also different types; the Contact metamorphism and the regional metamorphism. Contact metamorphism happens when magma is mixed with the solid rocks in the surroundings. For example when magma is starting to form igneous rock, it may increase that probability that it will reach the country’s rock and that’s affected the current formation of the rock. Regional metamorphism is also called as dynamic metamorphism. This happens when the pressure from underground makes the rock from above move and change into new rock formation

A construction company recently filled in a local pond to build new houses. Duringthe following weeks, a local scientist noticed a decline in the mosquito population in
the area. The scientist wants to conduct a study that will measure the change in the
local mosquito population over a period of three months. Which research method
would give the scientist the best data for conducting his study?
A. a three-month case study observing the behavior of animals that depend on
mosquitoes for food
B. a survey asking residents about their observations of the local mosquito
population
C. a collection device in the area that counts the number of mosquitoes caught
weekly
D. a controlled lab experiment with mosquitoes that limits watercolor the
experimental group

Answers

Answer: (C.) a collection device in the area that counts the number of mosquitoes caught

weekly

Explanation: I took the test :D

Final answer:

The most suitable research method for measuring a change in the mosquito population due to construction would be 'a collection device in the area that counts the number of mosquitoes caught weekly'. This method provides quantifiable, reliable data over the three-month study period.

Explanation:

To thoroughly study the change in the local mosquito population due to the construction, the most suitable research method for the scientist would be to use 'a collection device in the area that counts the number of mosquitoes caught weekly' (option C). This method would provide direct, quantifiable data about the mosquito population, showing changes on a weekly basis over the three-month study period.

A case study (option A) would not provide direct data about the mosquito population. Instead, it would provide indirect observations through the behavior changes of animals that prey on mosquitoes. Similarly, a survey (option B) relies on residents' subjective observations, which may not be reliable or accurate. Finally, a controlled lab experiment (option D) does not account for the plethora of variables present in a natural environment, thus limiting its effectiveness in this situation.

which contributes to acid rain? A. burning fossil fuels B. nuclear power C. solar power D. hydroelectric power

Answers

The answer is (A) burning fossils fuels releases excess amounts of CO2 ( Carbon dioxide) which reacts with H2O in the atmosphere.
CO2 + H2O -> H2CO3

H2CO3 is known as carbonic acid.
Carbonic acid contributes to problems such as ocean acidification and can dissolve limestone ( CaCO3) sculptures.
Shown by this reaction H2CO3 + CaCO3 -> Ca(HCO3)2 producing Calcium Hydrogen Carbonate.

There are also different causes of acid rain such as Sulfur Dioxide (SO2) and Nitrogen Oxide (NO) which can cause respiratory problems.
