Why is water pollution a concern if water is continuously cycled through Earth's systems?
Answer:The Earth's Water Cycle involves Evaporation, Condensation, and Precipitation. Evaporation purifies the water resulting to the replenishment of freshwater to the Earth.
Water pollution is a concern despite of the water being continuously cycled through Earth's systems because the source of pollution is has not been removed.
Water pollution is defined as the contamination of bodies of water. Pollutants are directly or indirectly released to the bodies of water causing the water to be polluted.
Imagine: A river is filled with garbage, it is polluted. The water from the river undergoes the water cycle but since the garbage is still present in the river, the freshwater that comes from precipitation becomes polluted.

Sally made a diagram to show one way that Earth's systems interact near a volcano
1. Identify the process that sally is moldering in her diagram
2. Explain how the individual parts shown in the model come together to form a cycle
The process that Sally is modeling in her diagram is the "Role of Volcanoes in the Earth's Systems". This particular system is called "the Cycle of Rock and Soil formation"
How do the individual parts of the model form the cycle?The cycle of soil formation starts with the production of molten magma by the volcano.
The magma solidifies and cools, then they are transported, deposited and go through lithification.
After lithification, they become sedimentary rocks, and then through exposure to pressure, they become metamorphic rocks.
Over the years, as more and more layers are deposited onto the metamorphic rocks, pressure and heat build up creating molten magma.
The magma creates igneous rocks which after many years may be produced again as molten magma through an active volcano.

The populations of zebras and wildebeests decrease when the grasses decrease. They also slowly increase when the rainy season brings new grasses to eat. This represents a
climax community
biological surplus
peak phenomenon
sigmoid phenomenon
Answer:
The correct option is "D", the sigmoid phenomenon because Populations that exhibit the sigmoid pattern increase rapidly while food and habitat are abundant, and then slow down as regulatory factors such as lower birth rate and reduced food availability come into play. As the rate of population growth slows down to zero, the population reaches a fairly stable level.
sigmoid phenomenon! its super cool. like, i took the test yo!

which zone in the ocean is the most challenging to survive in?
Answer:
The Bathyal zone is the hardest to survive in.
Explanation:
Technically, the entire ocean is difficult to survive in. There's no oxygen and lots of scary ocean predators.
But the Bathyal zone, which is 1000 - 4000 meters below the surface of the ocean has no sunlight, making most of the sea creatures there have no eyes. Because this zone is so dark, with little food to survive in, fish don't hang out here.
