Answer
Photosynthesis
Explanation
The sun keeps the carbon cycle working by providing light energy. This light energy is used to carry out a process called photosynthesis by organisms that are known as producers. This process creates organic matter from carbon dioxide and water. Photosynthesis thus helps maintain the activity of carbon sinks.
Answer:
Factors that affect the speed of a river include the slope gradient, the roughness of the channel, and tides.
Explanation:
Convection- is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, including molten rock. Convection includes sub-mechanisms of advection, and diffusion.
Explanation:
Cities become warmer than their rural surroundings due to buildings, roads and other infrastructure replacing open land and vegetation. “Surfaces that were once permeable and moist,” writes the“become impermeable and dry.”
During the daylight hours, temperatures inside large cities range between 1.8 and 5.4 degrees F warmer than their surrounding areas. At night, city temperatures can be as much as 22 degrees F warmer.
This phenomenon was believed to be the result of concrete and other structures absorbing heat throughout the day and then gradually releasing it at night. But a new study published last week in the journal Nature offers a different explanation: Convection.
How air moves through a city during the day has a greater role in trapping heat, the study claims, than the disappearance of vegetation and the existence of urban structures.
Answer:
Photosynthesis is the process of converting light energy into chemical energy in the form of glucose, in small structures called chloroplasts. ... In cellular respiration, the energy stored in the bonds of the glucose molecule is broken down and transformed to another type of energy, ATP.
Photosynthesis is the process plants use to convert energy from the sun into usable energy for their cells. Plants use the light energy of the sun, carbon dioxide, and water to make glucose (a sugar), and oxygen. The energy of the sun is captured and stored in the bonds between atoms in glucose molecules.
The tiny compartments where photosynthesis occurs are called chloroplasts, using a pigment called chlorophyll, which makes the plants green. The first energy transformation occurs when light energy from the sun is converted to chemical energy in the form of adenosine triphosphate (or ATP) and another molecule called nicotinamide adenine dinucleotide phosphate (or NADPH). ATP and NADPH provide the energy needed for the next energy transformation.
The plant cells then use the ATP and NADPH to assemble molecules of carbon dioxide and other carbon chains into glucose molecules. The glucose molecules can then be linked together to form cellulose, which plants can use to grow new leaves and stems.
The quality of being eccentric.
