The sun
Evaporation.
The earth is on a constant rotation and coincides with patterns of other stars as well as the sun and moon. Movement is natural in our atmosphere and always occurs.
The air in the Troposphere heats up as it absorbs sunlight, causing it to expand and become less dense. This leads to vertical movement of air, creating convection currents that drive weather patterns and circulation in the atmosphere.
Yes, a planet generally needs an atmosphere to have weather because weather involves the movement and interaction of air masses, which is facilitated by an atmosphere. An atmosphere helps regulate temperature, pressure, and moisture levels, which are all essential for weather phenomena like precipitation, wind, and storms to occur.
Carbon dioxide (CO2) is the molecule in which carbon is found in the Earth's atmosphere.
Carbon dioxide (CO2) is the molecule that enters a leaf from the atmosphere during photosynthesis.
Carbon dioxide (CO2) is the molecule that carries most of the carbon in the atmosphere.
Carbon is stored in the atmosphere primarily as carbon dioxide (CO2) molecule.
convection
Gas movement is greater.
actin myosin and cell movement
reabsorption
In warmer temperatures, that space can/will expand, molecule movement will increase and collisions will occur. In cooler temperatures, that space can/will decrease & molecule movement will slow down.
h2
osmosis
No molecule movement at all.
