Chao is thinking about doing a project on plate tectonics for the school science fair. which design would best relate to how the movement in the earth’s mantle is related to plate motion? a pot of boiling water to which chao will add food coloring to show the movement of the water a flat shallow pan filled with a thick liquid heated by a hot plate with thick wooden blocks on top of the liquid a flat shallow pan filled with small metal beads topped by an assembled puzzle that is shaken from side to side a flat shallow pan filled with a thick liquid that can be heated by a hot plate with pieces of a thin plastic sheet floating on top of the liquid

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
