Which of the following best explains why the biosphere is a key component of the earth’s systems? a the biosphere is a key component of the earth’s systems because it is a common concept to many disciplines in science. b. the biosphere is a key component of the earth’s systems because the seasonal cycles directly affect primary productivity. c the biosphere is a key component of the earth’s systems because it drive the other systems by interacting with and exchanging matter and energy with the other spheres. d the biosphere is a key component of the earth’s systems because it has evolved to create the chemical composition of the planet we know today.

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
