What is the minimum temperature needed for rocks to go through metamorphosis?

20 brainliest for whoever answers correctly and answers all choose the statements that accurately describe china's "one child policy." china's "one child policy" began as soon as the communists came to power. the "one child policy" was meant to keep the population from reaching 700 million. the "one child policy" was meant to slow china's population growth. the "one child policy" began as a result of the country's war with japan. some people were allowed to have more than one child. the "one child policy" began in 1979. the "one child policy" was most enforced in urban areas. the "one child policy" ended at the start of 2016. china's population is current just under 1 billion people.

A/an map shows the types of rock and/or sediment present in a particular region. a map that uses a range of colors and shading to represent the elevation, depth, or landscape of specific features on earth is a/an map. to show the dominant weather pattern in a region over a long period, a scientist is likely to create a/an map. a map has contour lines, which connect points at the same elevation. a map that uses shading to represent rates of violent crime across a state is an example of a/an map.

During metamorphic processes, increased pressure and temperature can affect the of minerals in rock. rocks subjected to very high pressure are typically than others because mineral grains are squeezed together, and the atoms are more closely packed. during metamorphic processes, water facilitates the transfer of ions between and within minerals, which can the rate at which metamorphic reactions take place. the growth of new minerals within a rock during metamorphism has been estimated to be about per million years. metamorphism is commonly associated with convergent plate boundaries, where two plates move toward each other. during contact metamorphism, a large intrusion will contain thermal energy and will cool much more slowly than a small one. metamorphosed sandstone is known as the metamorphic rock made from metamorphosed shale, was once used to make blackboards for classrooms
