An area of a mountain has rocks with small cracks between them in the winter water flows into the cracks and freezes the expansion of water when ice forms causes the rocks to break down into smaller pieces is this and example of weathering or is it an example of erosion? how do you know?

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
