how does the amount of silica in magma affect the viscosity of magma?

Answers

Answer 1

Higher silica content means higher viscosity. But lower temperatures and low gas content mean higher viscosity. Hence, lower viscosity and low gas content mean higher temperature of magma.

The Tanakh, commonly known as the Hebrew Bible, is Judaism's holy literature, including the tales and teachings that constitute the cornerstone of the Jewish faith.

The history of the Jewish people, particularly their periods of servitude and struggle, is one of the primary topics of the Tanakh. The Tanakh contains stories like the Exodus, in which the Israelites were delivered from slavery in Egypt, and the Babylonian exile, in which the Jews were captured and forced to reside in Babylon.

The Tenakh is the primary sacred Jewish literature that controls every element of Jewish life. The Christian Bible's Old Testament is made up of the books of the Tenakh, however they are not in the same sequence.

how does the elevation of the north china plain compare with that of the plateau of tibet

Answers

Answer:

The plateau of Tibet is a very tall plateau in southwestern China.

Explanation:

Your question: how does the elevation of the north china plain compare with that of the plateau of tibet?

Answer: Plateau of Tibet, Chinese (Pinyin) Qingzang Gaoyuan or (Wade-Giles romanization) Ch’ing-tsang Kao-yuan, also called Tibetan Highlands or Qinghai-Tibet Plateau, vast high plateau of southwestern China. It encompasses all of the Tibet Autonomous Region and much of Qinghai province and extends into western Sichuan province and southern Uygur Autonomous Region of Xinjiang. The region lies between the Kunlun Mountains and its associated ranges to the north and the Himalayas and Karakoram Range to the south and southwest, respectively; it extends eastward to the Daxue Mountains and, farther south, the northern and central portions of the Hengduan Mountains. The plateau, which has an area of about 965,000 square miles (2,500,000 square km), is a region of tangled mountains and uplands that are generally above 13,000 to 15,000 feet (4,000 to 5,000 metres) in elevation. Mount Everest (Qomolangma Feng), rising 29,035 feet (8,850 metres) above sea level on the China-Nepal border, is the world’s highest peak (see Researcher’s Note: Height of Mount Everest).

The northern section of the plateau, called Qiangtang, is dotted with many brackish lakes; its southern section contains the headwaters of the upper Indus and Brahmaputra rivers. Other rivers that have their headwaters in the highlands are the Yangtze River (Chang Jiang), the Huang He (Yellow River), the Mekong, the Salween, and the Tarim. Grasslands are used for pasturage, and barley is grown on the plateau; forests grow on the slopes of valleys, particularly in the south. The most extensive farming in Tibet takes place on the fertile plains of the Brahmaputra River and its tributaries. Lhasa, the capital of Tibet, is the plateau’s major centre of population, economic activity, culture, and air and land transportation.

1. What is happening at Slit B? What feature occurs at the corresponding
Location on the seafloor?

Answers

At the location of the Silt B, the Magma is forced upward, thereby, creating new ocean floor and the feature which occurs at Silt B location is the central valley of the mid ocean ridge.

At the mid-ocean ridge, the seafloor is formed by plate tectonics which have active eruption features.

The mid-ocean ridge is where the seafloor spreading takes place along the divergent plate boundary.

In conclusion, at the Silt B, the Magma is forced upward, thereby, creating new ocean floor and feature of the Silt B location is central valley of the mid ocean ridge.

explain how weather and climate are also affected by geologic and geographic factors, such as mountains and ocean temperature

Answers

Answer: explanation on how geography affects the climate

Explanation:

Climate is the prevailing patterns of temperature and precipitation across a region. A region’s climate can be tropical or frigid, rainy or arid, temperate or monsoonal. Geography, or location, is one of the major determining factors in climate across the globe. Geography itself can be divided into components including distance from the equator, elevation above sea level, distance from water and topography, or the relief of the landscape.

Higher Latitudes Have Cooler Climates

Latitude is a measure of distance from the equator. Locations between the Tropic of Cancer and the Tropic of Capricorn, between 23 degrees north and 23 degrees south latitude, are considered tropical. As you move away from the equator, climates shift incrementally through subtropical, temperate, subarctic and, finally, arctic at the poles. The tilt of the Earth on its axis means that the further you get from the equator, the longer the area spends tilted away from the sun each year, and the cooler and more seasonal the climate.

Water Bodies Regulate Precipitation and Moderate Climate

Over 70 percent of the Earth’s surface is covered in water, so it makes sense that water bodies influence climate. Oceans and lakes are very good at storing the heat that is created when the sun’s energy is absorbed by the water. The water heats and adds moisture to the air above it, a process that drives the major air currents around the world. Water bodies also make the climate of adjacent land masses more moderate. They absorb extra heat during warm periods and release it during cooler periods. Warm, moist ocean air drives precipitation patterns around the world when it falls as precipitation as it is carried over cooler land masses.

Mountains Disrupt Air Flow

Mountain ranges are barriers to the smooth movement of air currents across continents. When an air mass encounters mountains, it is slowed and cooled because the air is forced up into cooler parts of the atmosphere in order to move over the obstruction. The cooled air can no longer hold as much moisture and releases it as precipitation on the mountain range. Once the air is over the mountain, it no longer has much moisture, and the leeward side of mountain ranges is drier than the windward side.

Higher Elevations Have Cooler Climates

Climates become cooler and the cold season lasts longer as elevation above sea level rises. This holds true for mountains and high-elevation plateaus, such as the steppes of Mongolia. Every 1.61 kilometers (1 mile) in elevation gain is roughly equivalent to moving 1,290 kilometers (800 miles) further from the equator. Mechanistically, higher elevations have lower air pressure, fewer atoms per unit of air to excite and, thus, cooler temperatures. Mountains frequently receive more precipitation than the surrounding lowlands, but many high-altitude plains are deserts because of their location on the leeward side of a mountain range or continental mass.

Explain how earthquakes form

Answers

Answer:

Explanation:

An earthquake is caused by a sudden slip on a fault. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. In California there are two plates - the Pacific Plate and the North American Plate.

The tectonic plates divide the Earth's crust into distinct "plates" that are always slowly moving. Earthquakes are concentrated along these plate boundaries.

How do subduction zones lead to the formation of volcanic activity?

Answers

Answer:

Thick layers of sediment may accumulate in the trench, and these and the subducting plate rocks contain water that subduction transports to depth, which at higher temperatures and pressures enables melting to occur and 'magmas' to form. The hot buoyant magma rises up to the surface, forming chains of volcanoes.

5-55. In a random sample of 10,000 college students, a research company found that 35.7% were involved in a
club and 27.8% studied 4 or more hours per day. When they reported their findings, the research company
indicated that 53.4% of college students were either involved in a club or they studied 4 or more hours per day.
Given this information, what is the probability that a college student is involved in a club and studies 4 or more
hours per day?

Answers

The probability that a college student is involved in a club and studies 4 or more  hours per day is 9.92%.

Data and Calculations:

College student population = 10,000

Students involved in a club = 35.7% or 3,570 (10,000 x 35.7%)

Students who studied 4 or more hours per day = 27.8% or 2,780 (10,000 x 27.8%)

Students who involved in a club or studied 4 or more hours per day = 53.4% or 5,340 (10,000 x 53.4%)

The probability that a student, who is involved in a club, studies 4 or more hours per day is 9.92% (35.7% x 27.8%).

Thus, the probability that a student involves in a club and studies 4 or more hours per day is 9.92% or 992 students out of 10,000.
