Answer:
D nitrogen because it makes up most of our atmosphere
The atmosphere consists of 4 layers: the troposphere, stratosphere, mesosphere, and thermosphere. The troposphere is the lowest layer of the atmosphere. This is the layer where we live and where weather happens. Temperature in this layer generally decreases with height. The boundary between the stratosphere and the troposphere is called the tropopause. Above the tropopause lies the stratosphere. In this layer the temperature increases with height. This is because the stratosphere houses the ozone layer. The ozone layer is warm because it absorbs ultraviolet (UV) rays from the sun. The mesosphere is the layer above the stratosphere.This layer also contains ratios of nitrogen and oxygen similar to the troposphere, except the concentrations are 1000 times less and there is little water vapor there, so the air is too thin for weather to occur. The thermosphere is the uppermost layer of the atmosphere. In this layer the temperature increases with height because it is being directly heated by the sun.
I got this info from North Carolina Climate Office.
Hope this helps!!
B.evaporation because when heated water evaporates
Answer:
Lobster
Explanation:
Lobster was also known as the poor man's meal because the overabundance of these guys made it easy for people with no money to get their protein. In fact, these crustaceans were fed to prisoners, apprentices and slaves.
Answer:
The layers constitute fossils, calcium carbonate rocks
Explanation:
- Limestone is a biologic sedimentary rock and is formed by the collection of shells and debris. It can also be formed by the chemical process of sedimentary and precipitation of calcium carbonate.
- The limestone is composed of calcium carbonate, calcite, feldspar, and Quartz. Limestone represents karst topography and consists of the chemical composition of clay, iron, feldspar, and quartz. These are arranged in layers.
