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.

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.

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
differential precipitation between the equator and deserts is caused by hadley cells, which include:
Differential precipitation between the equator and deserts is caused by hadley cells, which include at the equator,more water evaporates into warmer air, warm air rises and cools and cold air holds less moisture so clouds form and water rains back to surface.
Air rises near the Equator, but rather than flowing all the way to the poles, Coriolis deflection produces sinking air at about 30° north and south latitudes as shown on the right side of the diagram below. This vertical motion in the tropics is so well defined that it has a name: the Hadley Cell.
Rising air in the Hadley cell along the equator produces deep clouds, thunderstorms, and rain in a band of low pressure called the Intertropical Convergence Zone (ITCZ).
Sinking air near 30° latitude causes high pressure areas called the subtropical highs. The highs produce clear skies and calm winds in a latitude band sometimes called the Horse Latitudes, which lie just north of the Hawaiian Islands and dominate Hawaiian weather.
At the highest latitudes, circulation is similar to the Hadley cell, except much smaller. Air sinks over the poles, where Polar High pressure, clear skies, and cold air dominate, then flows equatorward and rises again at the Polar Front.

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.

the period with mild climate between glacial advances is called a(n): orogeny interglaciation transgression regression
The period with mild climate between glacial advances is called a(n): interglacial periods. We refer to eras with substantial ice sheets as "glacial periods" (sometimes known as "ice ages") and periods with less ice cover as "interglacial periods."
A geological phase of warmer global average temperature lasting thousands of years that separates successive glacial periods within an ice age is known as an interglacial period (or alternately, interglacial, interglaciation). At the conclusion of the Pleistocene, or roughly 11,700 years ago, the current Holocene interglacial started. The warmer interval between ice ages during which glaciers retreat and sea levels rise is known as an interglacial or interglacial epoch. Glacial periods have lasted between 70,000 and 90,000 years during the past 450,000 years, while interglacial periods endure roughly 10,000 years. Currently, we are in an interglacial phase. About 10,000 years ago, near the conclusion of the last glacial period, it started. Researchers are still trying to determine the origin of ice ages. The amount of sunlight that Earth receives from the Sun is a significant impact. Over the past 800,000 years, 11 such interglacial eras have been recognized by researchers, but the one we are currently in may be particularly long-lasting.
