B. Warmer temperatures cause rising sea levels
Answer:
D. set it outside and check on it every day
Explanation:
In order for Brittany to be able to study the soil erosion by using a simplified method of what the farmers do on the slopes to minimize it, she will need to take the pan, leave it outside, and check on it every day. By having the required shape, the soil will give somewhat an example of the soil on the slopes that has been plowed so that the furrows run along the hills. Since the hills do not move or tilt, the pan with the soil should be stable, static. Being put outside, it will be exposed to the natural conditions that cause the erosion, such as the water and wind. Brittany will need to check upon the soil every day and make detailed notes and measurements to see what the erosive effects are on it.
Answer:
The BOD5 for this sample is 5 mg/L
Explanation:
The BOD5 takes into consideration the difference between the initial DO and the final DO divided by the fraction of the sample tested in a 300 mL BOD flask. The problem states that the sample was directly placed in a BOD bottle so we assume that the volume used was 300 mL of the water sample. The fraction of water is 1 (300/300).
BOD5 = (10-5)/1
BOD 5 = 5 mg/L
Answer:
Earth science is a term that describes everything related to Earth. Earth science has four sections of study: lithosphere, hydrosphere, atmosphere, and biosphere. Every single of these sections has its area of study.
Explanation:
People who study and compare geology of other planets with the earth are called planetary geologists.
The lithosphere is a solid part of the earth located on the extern site.
The hydrosphere is the mass of water located on the planet.
The atmosphere is a mix of gases that are surrounding the planet.
The biosphere is living part of the planet.
