Answer:
How and why does the surface of the earth change
of the earth has changed?
It can be hard to describe change on the surface without bringing up the interior. Earth is a system of constantly changing interactions between interior, surface conditions, and external events.
Volcanoes bring up new material and even create land. The Hawaiian islands, for instance are a chain of volcanoes on the surface, but the underlying structure is a single magma plume. In a way, the entire chain of islands is a single volcano that breaks through different places as the crust moves over it.
On that note: plates. Earth is made of tectonic plates that constantly move. Some grind against one another, others collide, and some pull apart. Depending on direction and interaction, you get anything from mountains, to spreading valleys, oceans, and anything else you care to name. Mountains can almost be viewed as something akin to the ridges of build up ice on a window scraper.
Erosion by water, wind, sand, chemicals, and living things changes the surface too. Materials on the surface face an incredible number of forces breaking them down and dragging them away, even as those same forces in different places and situations deposit those materials in other places, building things back up.
“Stardust” is also a thing. Rocks, dust, debris, and all sorts of random, natural cra.,p is constantly hitting our atmosphere. Regardless of whether or not it stays mostly intact, some material breaks off, and most of it does tend to make it to the surface, adding tiny amounts of matter all the time. …of course something BIG enough hitting the surface can throw rocks and chunks of surface clear into space, so that’s a thing too.
Remember when I mentioned living things? Living things D.,IE! Gac.k! And when they do, they break down into organic gunk. Soil - the stuff we grow crops in - is basically minerals and dead things that are decaying into nutritious, yummy, dir.,t.
Weather changes things too. Rain erodes, but rain that soaks a rock, and then is frozen by low temperatures, breaks the rock. Too much rain can create flooding, which results in a lot of sediment moving downstream. Heat can dry things out, crack the ground, and even slowly cook one kind of soil into another. Lightning can make glass out of sand, snow can collapse weak ground, not enough rain can dry out ground that could si.nk down without the extra pressure, and too much rain can literally move mountainsides if enough water adds its weight to the rocks and dir.t.
It’s always changing, and there is always more complexity to go into when studying it. There’s seldom a single cause, or reason, or effect for anything.
Explanation:
Have a great day!
The surface of the earth is constantly changing.
Explanation:
Wind, water,and ice break down large rocks and move sediments on the surface. Some events, though, change earth's surface much more quickly. These include volcanic eruptions, earthquakes, and landslides.

Which of the following are characteristics of the tundra biome? (Choose all that apply.)
much rainfall throughout the year
low biodiversity
very cold temperatures
lack of trees
A lack of trees, a lack of biodiversity, and extreme circumstances are what most clearly identify the tundra.
What is Tundra Biome?The polar ice caps and the boreal woodlands (also known as taiga), it is located. Extremely low temperatures and barren, icy terrain define the tundra biome. The arctic tundra and the alpine tundra are the two different forms of tundra.
The Tundra Biome: The Ice Deserts of the World. The tundra is the coldest biome, with an average annual temperature of less than 5°C and yearly precipitation of less than 100 mm, most of it snow.
Only a few number of plants and animals can even thrive on the tundra due to its extreme weather conditions. The Finnish term "tunturia" is where the word "tundra" originates.
Therefore, a lack of trees, a lack of biodiversity, and extreme circumstances are what most clearly identify the tundra.

vermiform appendix is a vestigial organ in human being give reason.
Answer:
The human appendix may be considered as a vestigial organ as it has been proved that the removal of the organ after infancy does not create any harm. Vestigial in that sense means that the vermiform appendix seemingly has no functions or is useless now but they might have had functions previously which are lost someway due to evolution.
Explanation:
Vestigial organs are organs, tissues or cells in a body which are not functional anymore the way they were in their ancestral form of the trait. It is therefore authentication of evolution and hence were helpful in explaining adaptation.

Mia and Raphael are discussing the ketogenic diet, also known as Keto, as a way of losing weight. Using the Keto method depends on changing the proportions of nutrient macromolecules that are eaten
daily to adjust energy metabolism. Which group of macromolecules can be affected by Keto eating choices, and is used for long term storage plus happens to be insoluble in water?
O carbohydrates
Ads
O nucleic acids
O proteins
The group of macromolecules that can be affected by Keto's eating choices, and is used for long-term storage, in addition to being insoluble in water, is lipid.
The ketogenic diet consists of significantly reducing the amount of carbohydrates ingested daily and adding more fat to the diet.
After about three weeks of reducing carbohydrates from the diet, the body enters a metabolic state called ketosis, turning stored fat as the body's energy source.
Therefore, the ketogenic diet can bring benefits to the individual, such as accelerated weight loss and prolonged satiety, but it can also be a difficult diet to follow for long periods, as it is more restrictive.
The ideal, then, is always to seek specialized help when you want to achieve some aesthetic or health goal related to weight loss, so that the professional can develop a diet focused on the needs and individualities of each one.

Does the light independent pathway of photosynthesis continue to occur when the leaf disks are placed in the dark environment
Yes, the light independent pathway of photosynthesis continues to occur when the leaf disks are placed in the dark environment.
What is photosynthesis?“The process by which green plants make their own food in presence of sunlight, chlorophyll and carbon dioxide is called photosynthesis.”In this process oxygen molecule is released as by product.It has two pathways: light dependent and light independent.
In light dependent pathway, light energy is used by chlorophyll and is converted into chemical energy.In light independent pathway, the energy produced during light dependent pathway is used to convert carbon dioxide into carbohydrates. It occurs in the stroma of the chloroplast.Hence, it is true that the light independent pathway of photosynthesis continues to occur when the leaf disks are placed in the dark environment.

Define bottleneck effect.
Koyi hai? ✌️
Answer:
When disaster strikes, an ecosystem can change very quickly. When an event causes a drastic decrease in a population, it can cause a type of genetic drift called a bottleneck effect.Hope this helps ~Answer:
The bottleneck effect is an extreme example of genetic drift that happens when the size of a population is severely reduced. Events like natural disasters (earthquakes, floods, fires) can decimate a population, killing most individuals and leaving behind a small, random assortment of survivors.

what happens when an acid is added to a solution?
Answer:
pH is a measure of the concentration of H3O+ ions in a solution. Adding an acid increases the concentration of H3O+ ions in the solution. ... If an acid is added to a basic solution, the solution becomes less basic and moves toward the middle of the pH scale. This is called neutralizing the base.
