The chemical composition of the gases surrounding the earth has changed substantially over the past 4 billion years. one notable change was due to the emergence of photosynthetic organisms. the process of photosynthesis increased the amount of what gas in the atmosphere?

The process of photosynthesis increased the amount of oxygen in the atmosphere

Explanation:

Photosynthesis is the process by which plant manufacture their food using chlorophyll and sunlight in the presence of gas. They give out oxygen to the atmosphere and take in carbon dioxide from the atmosphere using the stomata present on their leaves

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
