Why does Earth’s surface change? How does Earth’s surface change?
Your paragraph should be a minimum of 5 complete sentences. Your answer to each question should include both an explanation and a few examples.
Question: "Why does Earth’s surface change? How does Earth’s surface change?"
Answer: "Earth is a system of frequent interaction between the surface conditions, interior, and external events. Many of Mother Nature's lets say 'Natural Disasters' is one of the many things that help to mold and shape our planet. Take, for example, volcanos into consideration: when the eruption begins within a volcano, it pushes up new material from underground, helping to create new land forms (this was how many of Hawaiian's islands were created.)
Shifting of tectonic plates within the Earth's crust and upper mantle is another reason. The plates are constantly interacting, and lets say, 'grinding' together, as well as some colliding and breaking apart. Any of these reactions to the shifting of the tectonic plates can build any of our landforms and landscapes (including mountain ranges, oceans, valleys, etc.)
Also, another case of nature, erosion of the surface from water, wind, sand, chemicals, and living land creatures can develop and mold the surface of Earth as well. Countless numbers of forces are frequently breaking down and departing the surface, moving and spreading the materials of the surface to other sides of the Earth, later on perhaps building new formations."

A parrot and dog are the two animals are able to generate internal heat to maintain their body temperature in a cold environment.
What is Cold Enviornment?Polar and tundra biomes are examples of cold settings. They are the world's coldest climates. At the poles are polar zones. The Arctic is formed in the north by sea ice, and Antarctica, which is covered in ice, forms the Arctic in the south.
Arctic tundra, which surrounds the north pole and stretches south of the taiga's coniferous woods, is found in the northern hemisphere. One-fifth of the area on Earth is made up of the tundra. Of all the biomes, tundra is the coldest and driest.
The name tunturia, which means treeless plain, is derived from the Finnish word for tundra. It is (soil that is permanently frozen) may exist on the ground, but the top layer melts over the summer.
Therefore, A parrot and dog are the two animals are able to generate internal heat to maintain their body temperature in a cold environment.

4. What could happen to our local environment if a company pumped materials into the
atmosphere which created a drastic pH change in the rain water?
Answer:
It would upset the balance of the environment and cause animals to die off from the toxic and then other animals would die since they were eating the animals that had died.
If a company pumped materials into the atmosphere which created a drastic pH change in the rainwater, it could have a number of negative impacts on the local environment like acid rain, eutrophication, risk of respiratory illness, and decreased visibility.
Acid rain: Rainwater with a pH of less than 5.6 is considered acid rain. Acid rain can damage trees, plants, and crops. It can also corrode buildings and infrastructure.
Eutrophication is the process of excessive nutrient enrichment in a body of water, leading to the growth of algae and other aquatic plants. This can deplete the oxygen levels in the water, killing fish and other aquatic life.
Increased risk of respiratory illness: Acid rain can irritate the lungs and airways, leading to respiratory problems such as asthma and bronchitis.
Decreased visibility: Acid rain can also reduce visibility, making it difficult to drive, fly, and see clearly.
The specific impacts of a drastic pH change in the rainwater would depend on the materials that were pumped into the atmosphere and the amount of material that was pumped. However, the impacts would likely be negative and could have a significant impact on the local environment.

Why are elk healthier if the top predator; the wolf, is healthy and hunting them?
Who is at the top of the food chain in Yellowstone.
Answer:
Temperate Zone Ecosystem
Explanation:
Yellowstone National Park has one of the largest temperate-zone ecosystems. Not to mention there is tons of diversity within the park from the wildlife, to the vegetation, and the lakes.
5 reasons why wolves make Yellowstone better:
1. Rebalanced elk & deer populations
2. Return of certain species: songbirds, beavers, eagles, & foxes
3. Vegetation species like aspen trees made a return
4. Enhanced tourism opportunities
5. They help to redistribute nutrients and provide food for other wildlife species
5 reasons why wolves make Yellowstone worse:
1. Decline of the elk herd that lives in the Northern range
2. Changed animal behaviors (mainly elk)
3. Attacking livestock & affecting ranchers
4. Reduced hunting opportunities
5. Pose a possible threat to tourists & pets
Elk are healthier because wolves prey on the sick and wounded elk since they are easy to attack. Wolves ruling out the sick elk help the herds by preventing any sicknesses/diseases. When elk aren't being hunted they spend most of their time feasting away which has negatively impacted vegetation and it can also hurt them (overeating). Now that wolves hunt them, they no longer overeat.
Wolves and bears are at the top of the food chain in Yellowstone. They prey on elk and bison as their main source of food.
