Starting with an igneous rock, choose the correct order for the steps in the rock cycle that could lead to the formation of a clastic sedimentary rock. 1. a clastic sedimentary rock forms a sediments compact together.2. igneous rocks are broken down into tiny pieces by weathering3. tiny igneous ricks are deposited in a valley by wind. a.1,2,3b.1,3,2c.2,3,1d.3,2,1

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

geologic time scale (for gradpoint) =)

what is the question?
