Volcanoes are often formed at plate boundaries. this is a convergent plate boundary. from the choices listed, pick the correct description of what happens before the volcano forms. a) denser continental plate pushes oceanic plate down. oceanic plate melts deep in the earth, magma rises up through weak spot. b) the less dense oceanic plate subducts under the denser continental plate. subducted plate melts due to heat and pressure. melted plate, now magma, rises up to the surface. c) as the more dense oceanic plate subducts under the less dense continental plate, it pulls the front edge of the less dense plate down, creating a deep zone or oceanic trench. d) the more dense oceanic plate subducts under the less dense continental plate. subducted plate melts due to heat and friction. melted plate, now magma, rises up to the surface.

Explanation:

lies are not protected speech because they have no social value.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
