How is the flow of radiant energy impacted by tectonic events

Factors that impact the energy flow of the Earth's systems, or its radiation balance, include tectonic events, such as earthquakes and volcanoes. These factors act as an internal forcing mechanism, or radiative forcing. Tectonic activity may also cause changes in the ocean circulation, which, in turn, causes a change in the energy flow.

Explanation:

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
