How do water, wind, and thermal energy from the sun move about the earth's surface?

Answers

When the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. ... “Convection is the transfer of heat through the movement of a fluid such as water or air.

Molecules move more quickly because the sun's light energy transforms into heat energy on the planet. While cooler polar air and water travel away from the poles and towards the equator, warm air and water molecules rise and move in the opposite direction.

What is light energy ?

The capacity to make different forms of light visible to human sight makes light energy a sort of kinetic energy. Light is referred to as an electromagnetic radiation that is produced by hot things like the sun, lasers, and lightbulbs. Photons, which are tiny energy packets, are present in light.

Water temperature, biological activities and plant photosynthesis and development are all impacted by light energy.

The air is heated by the sun, and warm air rises. The colder air from the surroundings is forced to enter to replace the rising heated air. The result of this is the wind. Ocean currents function similarly.

Thus, Molecules move more quickly because the sun's light energy transforms into heat energy on the planet.

Lucia is given a picture of several cells. Her task is to identify the cells as plant or animal
cells. How can she pinpoint the cells that are plant cells?
A. She should look for a cell membrane surrounding the cell.
B. She should look for cytoplasm that is filled with organelles.
C. She should look for a large nucleus in the center of the cells.
D. She should look for ovals full of green dots called chloroplasts

Answers

A.
Plant cells have a cell wall, animal cells do not.

Answer:

D She should look for ovals full of green dots called chloroplasts

Explanation:

Plant cells are the only cells that will have chloroplast as it helps the plant go through photosynthesis.

Sublimation is the process by which solids are instantly transformed into gases. The forces of attraction between solids are completely defeated when they absorb enough energy. Solids, such as dry ice, undergo sublimation.

What is sublimation?Similar to melting, freezing, and evaporation, sublimation is a form of phase transition, or change in a state of matter. Without ever entering a liquid phase, a substance transforms from a solid to a gas through sublimation. Typical sublimation examples include dry ice, which is solid CO2,additional elements that cannot be sublimated. A solid-solid combination is separated by sublimation when one of the components sublimes (transforms from solid to gaseous state without producing liquid) following heating, leaving the other non- sublimable components behind.Sublimation is the direct transition of a substance from the solid phase to the gas phase without passing through the liquid phase in between. Sublimation is an endothermic phase transition that occurs at temperatures and pressures lower than a chemical's triple point in the phase diagram.
