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.

What are the issues concerning the learning environment that must be addressed to make training effective?
The answer is very dependant on the magnitude of the class, the length of a room, the form of the room, or the equipment inside the room. In general, for just a small group of students.
Magnitude is a unitless measurement of an object's brightness in a specific passband, usually in the infrared or visible spectrum, but sometimes over all wavelengths. Hipparchus established an imperfect but methodical determination of a magnitude of items in ancient times. The apparent magnitude is indeed the brightness of the an object as seen from Earth in the night sky. The apparent magnitude of an object is determined by its inherent luminosity, distance, and the extinction that reduces its brightness. The absolute magnitude describes an object's inherent luminosity and is defined as being equal to the peak amplitude that the object would possess if it were put at a specific distance from Earth, 10 parsecs with stars.

what does the level of genetic variation in neanderthals suggest about neanderthal population changes during the course of their existence on earth?
Neanderthal, also called Neandertal, was a subspecies of early modern human populations (Homo sapiens) that lived between 35,000 and probably 24,000 years ago.
This group of archaic humans first appeared between 2.6 million and 11,700 years ago, or at least 200,000 years ago. As far north as present-day Belgium and as far south as the Mediterranean and southwest Asia, Neanderthals lived in Eurasia, from the Atlantic areas of Europe eastward to Central Asia.

How do whales survive in water?
Because of a layer of fat called blubber that covers their entire body beneath the skin, whales can survive in deep or icy arctic water. Compared to the fat present in other mammals, blubber is substantially thicker.
The lungs of marine mammals are substantially larger than those of humans, allowing them to breathe in more air with each breath. Additionally, each time they inhale and exhale, they exchange more air. Additionally, their red blood cells contain more oxygen. Contrary to the buoyancy supplied by water, their bodies are not built to support that amount of weight on land.
Without the buoyancy and weightlessness of the ocean to support it, the whale's own body weight would destroy its organs after only a few minutes on land. Whales are marine mammals that live best in the ocean, but they cannot survive in freshwater conditions, at least not for very long. In actuality, all species of whales that are currently understood prefer saltwater habitats to freshwater ones for a variety of reasons.

what is the difference between faults and joints? group of answer choices joints are the result of compression, whereas faults are the result of tension. joints form from external stress, and faults form from cooling. joints form in place, whereas faults form because rock has moved. joints are the result of earthquakes, and faults are the result of weathering.
Answer: Joints form in place, whereas faults form because the rock has moved.
Explanation: A fault is a break in a rock mass along which movement has occurred. A joint is a fracture formed by the movement of the rock in a direction perpendicular to the plane of fracture.
Fault forms when rock above an inclined fracture plane moves downward, sliding along the rock on the other side of the fracture. Normal faults are often found along divergent plate boundaries, such as under the ocean where new crust is forming. Long, deep valleys can also be the result of normal faulting.
A joint is a type of extension fracture formed by the movement of the rock in a direction perpendicular to the plane of fracture. Joints form in solid rock that is stretched and its brittle strength (the point at which it breaks) is exceeded. When this happens, the rock fractures

How long can orcas stay above water?
They typically only submerge for around 20 minutes, but various orcas behave differently. Orcas can only endure a brief period of time on land. They have no problems breathing. Their fat retains too much heat, which is an issue.
Without the buoyancy and weightlessness of the ocean to support it, the orca's own body weight would destroy its organs after only a few minutes on land. Second, the orcas would quickly overheat, become dehydrated, and dry out because of the thick covering of blubber (over 1 ft. of blubber in certain species) and lack of water.
Because they are animals, whales and dolphins also breathe air into their lungs like humans do. Since they lack gills, they cannot breathe underwater like fish can. They breathe through a blowhole, which is a pair of nostrils on top of their heads. orcas breathe air via their lungs to obtain the oxygen they require (like humans). However, they breathe through their blowholes, which are placed on top of their heads and serve as noses instead of mouths.

Snow varies with temperature because it is mixed with rain, but the cold snow is more like hail with very large solid ice crystals.
What is Snow?Individual ice crystals that make up snow grow while hanging in the atmosphere, typically within clouds, and then fall to the ground, where they accumulate and alter further. By consuming sources of atmospheric moisture and frigid air, snowstorms organize and grow. By drawing supercooled water droplets that then freeze into hexagonal-shaped crystals, snowflakes form around airborne particles. Snowflakes can take on many different shapes, but the most common ones are platelets, needles, columns, and rime. It's possible for snow to blow into drifts as it builds up into a snowpack. Snow that has built up over time changes through processes like sintering, sublimation, and freeze-thaw. A glacier may develop in areas where the environment is sufficiently chilly for yearly accumulation. Other than that, snow usually melts seasonally, causing runoff into streams and rivers and refilling groundwater.

10) looking at question 9 what is is about the chemical composition that makes one volcano more explosive? relate the chemical composition of the volcano to the type of crust involved.
The magma composition that will cause the most explosive volcanoes is magma that contains huge amount of silica. Since silica makes explosive magma extremely viscous, or thick and sticky, this is crucial to understand. Aluminum and silicon oxides make up the majority of the continental crust. The rocks' pale color makes them resistant to deterioration.
Magmas differ in composition, which impacts viscosity. How a volcano erupts is greatly influenced by the composition of the magma. More viscous and erupting violently or not at all are felsic lavas. Less viscous and more effusive are mafic lavas. Volcanoes can take on a variety of shapes, which are determined by the makeup of the magma and the process of eruption. When a volcano produces lava that is very fluid (low in silica, or SiO2), the magma travels a great distance before cooling, creating a flat, shield-shaped volcano. The majority of island arcs were formed on oceanic crust as a result of the lithosphere's plunge into the mantle along the subduction zone. Because gas volume expands as pressure decreases, gas lends magmas their explosive nature. Magma is mostly composed of water vapour and carbon dioxide, with trace amounts of sulphur, chlorine, and fluorine gases.
