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.
Panama has forests volcanos and mountains that extend from the Costa Rican border to Colombia, South America
Answer:
I'm going with B kinetic energy from ocean currents
What was the passage or lesson about?
The explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the Redshift- Doppler effect.
<h3>What is the Doppler effect?</h3>
The Doppler effect is the difference that occur between the frequency of a wave in relation to observer from the wave source.
The wavelength changes with change in the frequency.
<h3>How does the Doppler effect explain the redshift?</h3>
As an object moves away from Earth, the waves moves to the red end of the electromagnetic spectrum and becomes elongated. This results to the increase in wavelength.
Therefore, the explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the redshift-Doppler effect.
