Agarden aboard the international space station allows space scientists to research the growth of plants in space. this research is important because astronauts will need to grow their own food to survive long space journeys.
what challenges would you expect scientists to face when growing plants in space? what challenges will the astronauts have with meeting their own energy needs?
scientists are also evaluating plants for gene mutations that would them grow better in space environments. what traits could a plant have that would it grow better in space?

the trilobite is used as an index fossil for various geologic time periods as specific types of the trilobites were present in different geological time periods. they are a group of marine arthropods belonging to the class of trilobita.

explanation:

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).

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
