What property of the liquids in the lava lamp was critical to get motion? DENSITY: Answer is C. You need a variation in density in order to get
gravity to work on moving the blobs up and down. Less dense = rise, more dense = sink (as compared to the surro
physical weathering: 1. freeze/thawwater into crack, up cracks; 2. saltsalt crystals expand with frozen water!
chemical weathering: a) dissolution: ions of a substance become dissolved (NaCl + H2O) NON SILICATES; b) hydrolysis:
SILICATES; chem reactions H
downslope movement of soil & weathered rock resulting from gravity alone: mass movement classification: what is
moving, how it moves, and how fast it moves (not the mechanism that triggered movement); factors that cause MM:
factors that influence slope st
The general definition of a mineral
encompasses the following criteria:!
Stable at room temperature!
Represented by a chemical formula!
Usually abiogenic (not resulting from the
activity of living organisms)!

The convergence of two tectonic plates develops some of the most remarkable structural
and topographic features on our planet. At convergent plate margins, great slabs of
oceanic lithosphere slide ponderously into Earths int
