Scientists have noticed patterns in the Earth's seafloor structures. for example, volcanic ridges are typically located in the center of the oceans, and trenches are typically located along the edges of continents. in addition, sea floor rocks found at the trenches are usually older than the sea floor rocks on at the mechanic bridges. which explanation of the past movement of earth's plates is best supported by this information? A. The continents were separated when new crust was formed at the edges of the continents pushed older crust towards the center of the ocean.

B. The continents were pushed apart when new crust formed in the center of the ocean and pushed older crust away from the volcanic ridges.

C. The formation of new crust at the trenches widened the seafloor and pushed the edges of the continents away from one another.

D. The Earth's crust formed at the trenches and moved towards the volcanic ridges to make room for newer crust, pushing the continents apart.​

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.

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.
