Hey there!
Airplanes must be pressurized when flying at high altitudes so that the oxygen levels stay normal for us to breathe. The higher you go up, the thinner the air gets, which causes breathing problems for us humans.
Thank you!
Answer:
D. Heavy rainfall saturated the soil and destabilized the over-steepened slope.
Explanation:
The mud slide must have occurred in La Conchita California due to heavy rainfall which saturated the soil and destabilized the over-steepened slope.
Mud slide or mud flow is a form of mass wasting in which slope moves downward due to instability of the materials. They usually influenced by the effect of gravity on steep slopes.
- Prior to the mass moving event on the in the county, there was an unprecedented 14-15days streak of rainfall.
- The rain saturated and lubricated the soil bringing a reduction in their cohesion and ultimate movement.
- This led to the sliding down of the masses on the slope.
Answer:
The expanding gas is exerting pressure and doing work on the walls of the balloon causing it to inflate.
Explanation:
"Dry ice" turns into gas in a process called<em> "sublimation." </em>
This is what happens when Bob placed several pieces of dry ice inside the empty water bottle. The<em> room temperature</em> allowed the dry ice to undergo<u> sublimation</u>. It then transformed into gas which exerted pressure on the walls of the balloon as it is expanding. <em><u>This is the reason why the balloon became inflated.</u></em>
So, this explains the answer.
Answer: The answer is D.
Explanation: A metro area is usually a large populated city, but that also includes forests and/or less populated suburbs around the city. <u><em>I hope this helps!</em></u>
