Which of the following best explains how phototropism is different from gravitropism? O Phototropism is a stage of photosynthes is gravitropism is movement of roots into the sol
Phototropism is movement of plant parts into the sol, gravitropism is movement of plant parts toward the sun.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint
