Explanation
EPA stands for Environmental Protection Agency was founded in the year 1970 in the month of December.
EPA’s role in environmental regulation are:
- EPA's role to protect, analyzing, Monitoring the environment.
- Implementation of the environmental law.
- Environmental guidance and plan.
- EPA goal is to improve the environment condition and contribute to making our ecosystems sustainable.
- The EPA controls the distribution, production, processing, and handling of chemicals and pollutants.
- Assuring the Safety of Chemicals so that it does not cause any harm to the environment.
Answer:
Partial melting occurs when only a portion of solid is melted. It is thus enriched in the chemical components of minerals with lower melting temperatures and the remaining unmelted portion of the rock is composed of minerals with highest melting temperatures. Partial melting preferentially enriches melts with incompatible elements.
Partially melted rock do not usually experience complete melting inside the Earth, due to their different chemical composition and their melting points.
It is thought that partial-melting processes play a major role in generating more-defined liquids from less-evolved ones, so that many basalts may be the result of partial melting in the upper mantle, and many granites may have derived partly or completely from the partial melting of continental crust (anatexis).With increasing temperature and pressure, the subducted oceanic crust (of basic composition) first undergoes metamorphism and then begins to melt or release watery fluids; this material rises into the overlying mantle, which may also begin to melt, giving rise to intermediate magma.
Answer:
The Suez Canal is a man-made waterway connecting the Mediterranean Sea to the Indian Ocean via the Red Sea. It enables a more direct route for shipping between Europe and Asia, effectively allowing for passage from the North Atlantic to the Indian Ocean without having to circumnavigate the African continent.
