The rock doesn't really completely melt during metamorphism. Heat and pressure cause changes in the rock. Because the minerals must be stable under the new pressure and temperature conditions, rocks change during metamorphism.
Metamorphism occurs since some minerals are only stable under certain pressure and temperature conditions. Chemical reactions occur when pressure and temperature change, causing the minerals in the rock to change to a conglomeration that is steady at the new temperatures and pressures.

Continental glaciers are usually thicker in their center. Looking at this map of crustal rebound in Canada, there were two centers of ice sheet flow. Which covered Canada in the Pleistocene.
An ice sheet is a mass of glacial ice more than 50,000 square kilometers (19,000 square miles). About 99% of the freshwater on Earth is found in ice sheets, which are also known as continental glaciers. Ice sheets transform into ice shelves as they reach the shore and cross the ocean. Only Antarctica and Greenland are the most polar places with continental glaciers. Large portions of Canada, Europe, and Asia were once covered by continental glaciers, and these glaciers are to blame for many of the regions' distinctive geographical features. On land, glaciers develop. They are composed of snow that has fallen and has been compacted over many centuries into ice. Due to the influence of gravity, they progressively descend. The polar regions, including Greenland, the Canadian Arctic, and Antarctica, are home to the majority of the world's glaciers. Compare oceanity to an ice sheet that covers a sizable portion of a continent. An ice sheet is another name for a continental glacier. The reason why these ice sheets are called glaciers is because they cover continental land masses.

Ranking the following modes of preservation according to their ability to preserve an organism’s original living condition and body details is
C. original preservation B. casts A. carbonization D. recrystallization
Details of each process,
Original preservation is the most typical method of preservation since it largely or completely preserves the organism's remnants. This may occur in conditions when the creature is swiftly covered in tar or dirt or frozen in ice.Casts are created when an organism's surrounding silt or other material dissolves away, leaving a shadow of the organism's outline behind. This may be a useful method for maintaining an organism's general shape, but it offers little information on the internal organization of the creature.Carbonization is the process by which carbon is created from organic materials in an organism. An organism may experience this if it is buried in silt that contains a lot of organic material. Although an organism's general form can be preserved with carbonization, the internal structure of the organism is not.Recrystallization is a process where new minerals are added to the hard components of an organism to replace the old minerals. As the silt surrounding the creature is heated and compressed over time, this may occur. The initial form of an organism's hard components can frequently be obscured by recrystallization.Hence, original preservation is the most representative method of preservation since it preserves the organism's physical remnants and offers the most information about its original form.

this environment is found on a polar continent on a pretend world. what combination of temperature, precipitation, and humidity best describe environment d's climate?
A desert is the combination of temperature, precipitation, and humidity that most accurately describes the climate of an area. The social and environmental determinants of health are impacted by climate change.
A desert is a desolate region of the landscape with minimal precipitation, making living circumstances unfriendly for both plant and animal life. The absence of vegetation exposes the exposed ground surface to denudation. Arid or semi-arid regions make up around one-third of the Earth's geographical surface. This comprises a large portion of the arctic regions, which are frequently referred to as polar deserts or "cold deserts" because they receive minimal precipitation. The amount of precipitation that occurs, the temperature that prevails, the reasons for desertification, or the geographic location of a desert can all be used to categorize it. Large temperature differences between day and night impose stress on the rocks, causing them to fracture in fragments, which is how deserts are produced. Although deserts rarely see rain, there are sporadic downpours that might cause flash floods. Hot rocks can break when exposed to rain, and the shattered pieces and rubble that are left on the desert floor are further eroded by the wind. This gathers sand and dust particles, which can stay in the air for a long time and occasionally result in the creation of sand storms or dust storms. The surface can be worn away by wind-blown sand grains striking any solid item in their path. The wind flattens down rocks and creates consistent sand deposits.

This peculiar rock was produced during the Eocene epoch (34–55 million years ago), when ancient streams transported sediments (sand, silt, and clay) into floodplains. These sediments cemented and ascended as earthquakes transformed the low-lying plains into the Chuckanut Mountains and hills that we now recognise.
How do sediments form?
Because of erosion and weathering, boulders and even mountains turn into sediments like sand or mud. One kind of weathering is chemical weathering, often known as dissolution. This technique progressively removes stone by rinsing it in slightly acidic water. These three processes result in the raw elements for new, sedimentary rocks.

Floods happen in the wild. The ecology has been prepared for flooding, and they are a component of the water cycle. Floodwaters are absorbed by wetlands along riverbanks, lakes, and estuaries.
Floods, the most common sort of natural disaster, happen when an excess of water submerges normally dry ground. Floods are frequently brought on by prolonged periods of heavy rain, quick snowmelt, or storm surges from tropical cyclones or tsunamis in coastal locations. When rivers overflow their banks, the surrounding region experiences riverine flooding. Heavy rainfall is the main cause, but king tides, storm surge, snowmelt, and dam releases can also contribute to it. Flooding occurs naturally along every river and coastal locations. Sediments that are rich in nutrients can be carried by flood waters, helping to create a fertile habitat for plant life.
