Deforestation is a source of anthropogenic, or human caused carbon dioxide emissions because cannot consume carbon dioxide moleculesGiven that plants and trees reduce the amount carbon dioxide in the atmosphere, what does this indicate about the relative rates of photosynthesis and respiration in plants
Answers
Answer:
Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy. The carbon cycle. Most of Earth’s carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles. NOAA technicians service a buoy in the Pacific Ocean designed to provide real-time data for ocean, weather and climate prediction. NOAA buoys measure carbon dioxide NOAA observing buoys validate findings from NASA’s new satellite for measuring carbon dioxide Listen to the podcast Carbon storage and exchange Carbon moves from one storage reservoir to another through a variety of mechanisms. For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules. Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle. The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. Two-way carbon exchange can occur quickly between the ocean’s surface waters and the atmosphere, but carbon may be stored for centuries at the deepest ocean depths. Rocks like limestone and fossil fuels like coal and oil are storage reservoirs that contain carbon from plants and animals that lived millions of years ago. When these organisms died, slow geologic processes trapped their carbon and transformed it into these natural resources. Processes such as erosion release this carbon back into the atmosphere very slowly, while volcanic activity can release it very quickly. Burning fossil fuels in cars or power plants is another way this carbon can be released into the atmospheric reservoir quickly.Explanation:

A student is trying to model an ocean environment. What is the MOST important factor the student should add to the aquarium in order to make sure that the model is accurate?
A.starfish
B.seaweed
C.salt water
D.coral reef
Answers
Answer:
C: salt water
Explanation:
everything would be dead if there was no water
The most important factor while preparing a model of an ocean environment is Salt water. Marine ecosystems show high salinity. Thus, the correct option is C.
What is Ocean environment?Ocean ecosystems or environments are characterized by the important factors which include the availability of light, food and nutrients. Oceans have some unique properties which include high salinity, the freezing point which is slightly lower than that of fresh water, density which is slightly higher than other waterbodies, electrical conductivity which is much higher, and the slightly basic nature.
Oceans are important as they feed us, regulates the climate, and generate most of the oxygen which we use for breathing. They also serve as the foundation for much of the world's economy, supports important sectors from tourism to fisheries to the international markets.
Therefore, the correct option is C.

The formation of the oceans
d
The development of an ozone layer
Answers
Answer:
D
Explanation:
the ozone layer formed and began to shield the surface of the Earth from the harmful ultraviolet light. This allowed life forms to evolve to survive on the surface of the oceans and on land and also allowed organisms who metabolize oxygen (like us!) to develop.
The change in the Earth's atmosphere which allowed life to form is the development of an ozone layer. Thus, the correct option is D.
What is the Ozone layer?The ozone layer is a region of the Earth's stratosphere which absorbs most of the Sun's ultraviolet radiations. Earth's stratosphere contains a high concentration of ozone in relation to other parts of the atmosphere, although it is still present in small amount in relation to other gases in the stratosphere.
The ozone layer in the stratosphere absorbs a big portion of the radiations from the sun, preventing it from reaching the planet's surface. Most importantly, ozone absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light which comes from the sun that has several harmful effects.
Therefore, the correct option is D.

A layer of sedimentary rock lies next to a layer of igneous rock. If inclusions from the igneous layer are scattered in the sedimentary layer, then the layer of sedimentary rock is richer in minerals than the igneous layer.
Explanation:
The igneous rocks are a good source of minerals like pyroxene, mica, amphibole, olivine, etc. Some common minerals like quartz, feldspar, and muscovite are found in both igneous and sedimentary rocks. But the major clay minerals like calcite, gypsum, dolomite, and halite are only found in the sedimentary rocks. Thus, scattering inclusions from the igneous layers over the sedimentary layer would make the sedimentary layer richer in mineral_________________________________________________________
