A tectônica de placas é uma teoria que explica a formação e a atual distribuição dos continentes na Terra. Sobre essa teoria, podemos afirmar que: as placas tectônicas apenas se afastam uma das outras, separando os continentes. as placas que se afastam umas das outras formam cordilheiras no fundo dos oceanos. as placas podem colidir entre si, e a mais nova delas é empurrada para baixo da mais antiga. ela substituiu a teoria da deriva continental, que foi abandonada completamente.

Can someone me choose a broad topic and area of focus i am really doing this as a tally to see which one most people pick ok water pollution global warming endangered species atmosphere for the !

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
