Answer:
The Milky Way is much wider than it's thickness. So it is a narrow band with many stars in it, while the sky outside the band has much fewer stars.
Shapley's 20th-century observations of globular cluster orbits, which center on a point about 30,000 light years from our Sun, showed we weren’t in the center of the galaxy.
Explanation:
The structure of our galaxy is formed by the six paths as the nucleus, the central bulge a disk, has spherical arms ad spherical components and surrounded by a huge and large halo. Being a disk-shaped this galaxy is spiral in nature and denser stars are closer to the galaxy. The milky way is located about 30,000 light-years away from the sun and its galactic center is far from the center which is dominated by a supermassive black hole.1. In what one area in China are coal, iron ore and oil all found close to one another.
Along the eastern coast of China are coal, iron ore and oil all found close to one another.
Where are natural resources found in China?The so-called Chinese coal belt in northwest China, which includes Inner Mongolia and Xinjiang, produces enormous amounts of natural gas and petroleum in addition to coal. Every year, China invests billions of Yuan in the geological discovery of resources, mainly oil and gas. The Chinese provinces with the highest concentrations of iron ore include Liaoning, Sichuan, Hebei, Inner Mongolia, and Shanxi. Gold and lead zinc got the largest funding for geological exploration among non-fossil resources, at around a billion yuan each year.

Name three forces that are constantly changing the earth
The three forces that are constantly changing the Earth are gravity, electromagnetism, and tidal forces.
Explanation:The three forces that are constantly changing the Earth are:
Gravity: Gravity is the force that pulls objects toward the center of the Earth. It is responsible for the weight of objects and determines their motion.Electromagnetism: Electromagnetic forces are responsible for many phenomena on Earth, such as the interaction between charged particles, the behavior of magnets, and the flow of electricity.Tidal forces: Tidal forces are caused by the gravitational pull of the Moon and the Sun on the Earth. These forces cause the rise and fall of ocean tides and create stresses on the Earth's crust.Kevin uses 32 ounces of dried apples and 18 ounces of dried cranberries to make a fruit snack. He plans to sell the snack in 1 2 -pound containers. How many containers will he fill? Will any fruit snack be left over? Kevin will fill containers. There left over.
Kevin will fill 6 containers with his fruit snack mixture, and there will be 2 ounces of the mixture left over after filling these containers.
Kevin uses 32 ounces of dried apples and 18 ounces of dried cranberries to make a fruit snack. He plans to sell the snack in 1/2-pound containers. A pound is equivalent to 16 ounces, so a 1/2-pound container would hold 8 ounces of fruit snack. To calculate how many containers Kevin will fill, we first find the total amount of fruit snack by adding the weight of the dried apples and cranberries:
32 ounces (apples) + 18 ounces (cranberries) = 50 ounces (total fruit snack)
Next, we divide the total amount of fruit snack by the container size to find the number of containers he can fill:
50 ounces \/ 8 ounces per container = 6.25 containers
Since Kevin cannot have a fraction of a container, he can fill 6 complete containers, and there will be a remainder. To find the leftover amount, we calculate:
50 ounces - (6 containers x 8 ounces) = 2 ounces left over
Therefore, Kevin will fill 6 containers, and there will be 2 ounces of fruit snack left over.
The Earth's diameter at the poles is _____.
A)equal to its diameter at the equator
B)greater than its diameter at the equator
C)less than its diameter at the equator
The Earth's polar diameter is less than its equatorial diameter, making it an oblate spheroid with a flattened shape at the poles. The option (C) is correct.
Due to this bulge, the equatorial diameter is about 12,756 km (7926 miles), while the polar diameter is slightly less, about 12,714 km (7900 miles). The Earth's rotation causes this equatorial bulge, resulting in a larger diameter when measured across the equator than from pole to pole.
This asymmetry results in a flattened appearance at the poles and a bulging at the equator. This deviation from a perfect sphere is due to the planet's rotation, causing the centrifugal force to be stronger at the equator, pushing outward and flattening the shape.

women in america have rights
Explanation:
Saudi Arabia is an extremely male dominated culture with strict adherence to tradition and the religious laws of Islam, called Sharia. “Islam provides the framework for a unique form of government which continuously strives to raise the living standards of its people while cherishing the religious, ethnic, and moral values of the Kingdom’s diverse tribes” (Luna 9). Sharia guidelines maintain that an unmarried woman is the ward of her father, a married woman is the ward of her husband, and a widowed woman is the ward of her sons. There is no concept of a single women, alone in Saudi Arabia. Women must ask permission from their male guardians to do virtually anythin
Saudi Arabia Today
There is no denying that women in the Unites States have made great strides towards full gender equality, but there are still things to be done. In Texas alone, the past year has seen Senate controversies on both pay equality and reproductive rights.
In June 2013, Rick Perry vetoed a bill meant to prevent wage discrimination against women. The Equal Pay Bill or HB 950 would bring Texas state law in line with the federal Lily Ledbetter Fair Pay Act, which makes it easier for women to sue employers over wage discrimination.
Wendy Davis successfully completed an 11 hour filibuster to defeat a controversial anti-abortion bill aimed at severly cutting funding for abortion services across Texas. However, Rick Perry called a 2nd Special Session in order to get the bill passed. If passed it would effectively limit women's reproductive rights and options.
There has been some change in women's roles and rights in Saudi Arabia over the last fifty years. However, it must be noted that Saudi women do not want to become "westernized," but they do want some of the freedoms and rights that American women and women all over the world have been provided.

Women right's are different around the globe, but the rights of Saudi Arabia and the United States are almost polar opposites. Women's rights have been an issue in the USA since the 1800s, while Saudi Arabian women have only recently begun their fight for equality from the oppression of the strict Islamic laws under which they live. Women's gender roles play a significant role in the rights women are given. In Saudi Arabia, women are seen as subordinate to men and therefore few rights are given. However, some Saudi women reject the push for more rights, stating "Saudi women are the luckiest in the world and Saudi Arabia is the closest thing to an ideal and pure Islamic nation. We don't want imported Western values to destroy that" (Ambah)
Saudi Arabia’s unique mix of the traditional and modern present a distinct set of problems for women's rights. Saudi Arabia’s economy has evolved very quickly in the last fifty years, from a tribal community to a world power, but their culture has not had time to catch up. Women’s rights must be addressed in order for real and effective change to take place, but the current laws oppress them and limit their involvement in society.
Surface winds typically blow at an angle to isobars on a weather map, while winds aloft move air in a direction nearly parallel to the isobars. Which of the following factors best explains why surface winds move differently than winds aloft?a) africtionb) humidityc) clear air turbulenced) the pressure-gradient force
Answer:
The correct answer is A. Friction
Explanation:
Surface winds typically blow at an angle to isobars on a weather map, while winds aloft move air in a direction nearly parallel to the isobars. FRICTION is the factor that best explains why surface winds move differently than winds aloft.
Friction is a force that holds back the movement of a sliding object. It is also the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
It is also the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
Friction is the factor that best explains why surface winds move differently than winds aloft.
Explanation:The factor that best explains why surface winds move differently than winds aloft is friction. Friction between the wind and Earth's surface causes surface winds to slow down and change direction, resulting in an angle to isobars on a weather map. In contrast, winds aloft are not affected by surface friction and therefore move in a direction nearly parallel to the isobars.

Who created the modern model of the solar system by discovering that the planets move in eclipse
Answer:
I do believe that it was Johannes Kepler
Explanation:
Answer:
Kepler derived the three laws of planetary motion which changed the model of the Solar System and the orbital path of planets.
Explanation
The historical models of the Solar System began during prehistoric periods and is updated to this day. The models of the Solar System throughout history were first represented in the early form of cave markings and drawings, calendars and astronomical symbols. Then books and written records then became the main source of information that expressed the way the people of the time thought of the Solar System.
New models of the Solar System are usually built on previous models, thus, the early models are kept track of by intellectuals in astronomy, an extended progress from trying to perfect the geocentric model to eventually using the heliocentric model of the Solar System. The uses of the Solar System model began as a time source to signify particular periods during the year and also a navigation source which is exploited by many leaders from the past.
Astronomers and great thinkers of the past were able to record observations and attempt to formulate a model that accurately interprets the recordings. This scientific method of deriving a model of the Solar System is what enabled progress towards more accurate models to have a better understanding of the Solar System that we are in..
In 1609, Johannes Kepler, using his teacher's (Tycho Brahe) accurate measurements, noticed the inconsistency of the geocentric model and confirmed the heliocentric model is a more accurate and consistent model. Kepler derived the three laws of planetary motion which changed the model of the Solar System and the orbital path of planets. The three laws of planetary motion are:
All planets orbit the Sun in elliptical orbits and not perfectly circular orbits.
The radius vector joining the planet and the Sun has an equal area in equal periods.
The square of the period of the planet (one revolution around the Sun) is proportional to the cube of the average distance from the Sun.
The third law explains the periods that occur during the year which relates the distance between the Earth and the Sun.
Galileo's discoveries
With the help of the telescope providing a closer look into the sky, Galileo Galilei proved the heliocentric model of the Solar System. Galileo observed the phases of Venus's appearance with the telescope and was able to confirm Kepler's first law of planetary motion and Copernicus's heliocentric model. Galileo claimed that the Solar System is not only made up of the Sun, the Moon and the planets but also comets. By observing movements around Jupiter, Galileo initially thought that these were the actions of stars. However, after a week of observing, he noticed changes in the patterns of motion in which he concluded that they are moons, four moons.
Newton's interpretation
After all these theories, people still did not know what made the planets orbit the Sun. Until the 16th century when Isaac Newton introduced The Law of Universal Gravitation. This theory claimed that between any two masses, there is an attractive force between them proportional to the inverse of the distance squared.

Because of a limited freshwater supply, Dubai has to maintain a large-scale desalination process. How does the desalination process affect the environment? A. It causes aquifers to dry up. B. It causes air pollution. C. It makes oil spills more likely. D. It contributes to water salinity problems.
Answer: its b
Explanation:
Final answer:
The desalination process in Dubai primarily contributes to water salinity problems due to the discharge of highly saline wastewater, although it can also cause air pollution indirectly if the energy used is from fossil fuels.
Explanation:
The large-scale desalination process utilized in Dubai to address the limited freshwater supply has significant environmental impacts. The most pertinent one, in relation to the options provided, is that it contributes to water salinity problems. Desalination plants typically discharge highly saline wastewater back into the ocean, which can lead to an increase in the local seawater salinity, affecting marine ecosystems. The process itself is quite energy-intensive and can lead to air pollution, depending on the source of the energy used, but this is not typically considered the primary environmental effect. The options of causing aquifers to dry up or making oil spills more likely are not direct consequences of the desalination process.

As understood by modern geologists, the principle of uniformitarianism implies that ____________.
a. the Earth has always had the same basic appearance that it has today.
b. igneous, metamorphic, and sedimentary rocks are uniformly mixed throughout the crust.
c. physical processes observed today (such as erosion and volcanic eruptions) have been active in the past at approximately the same rates.
d. physical processes observed today (such as erosion and volcanic eruption) occurred much more rapidly in the past, quickly sculpting the Earth’s surface.
The correct answer is c. physical processes observed today (such as erosion and volcanic eruptions) have been active in the past at approximately the same rates.
This is because the principle of uniformitarianism, as understood by modern geologists, states that the same natural processes that operate in the present have been occurring throughout Earth's history at relatively consistent rates.
Option a, stating that the Earth has always had the same basic appearance that it has today, is incorrect because the Earth's appearance has changed significantly over geological time due to processes such as erosion, tectonic movements, and climate changes.
Option b, stating that igneous, metamorphic, and sedimentary rocks are uniformly mixed throughout the crust, is also incorrect as different types of rocks are distributed unevenly in the Earth's crust based on geological processes and history.
Option d, Uniformitarianism suggests that geological processes have occurred over vast periods of time at relatively constant rates. While major events like asteroid impacts or catastrophic volcanic eruptions have occurred in Earth's history, the overall shaping of the Earth's surface is believed to have taken place gradually through the same processes we observe today

Answer:
b) Length d, height c
Explanation:
The question is incomplete. The complete question is stated below:
Triangle KLP is cut from parallelogram KLMN and moved to its right-hand side. What are the dimensions of the resulting rectangle LMQP ?
a) length d, height a
b) length d, height c
c) length d - b, height c
b) length d + b, height c
The diagram in the question has been attached to the answer.
SOLUTION:
The parallelogram KLMN had dimension base d and height c.
When right angled triangle KLP is cut from it, we are left with a right-angled trapezoid NPLM. Attaching a right angle triangle KLP to the right of the trapezium gives rectangle LMQP as
Right angled triangle KLP = Right angled triangle NMQ.
The dimension of the resulting rectangle LMQP is Length d, height c.
The diagram for the solution is sent as attachment.
The resulting rectangle LMQP has dimensions of length LQ = KL + LM and width LP = KM.
Since triangle KLP is cut from parallelogram KLMN and moved to its right-hand side, the resulting figure is a rectangle LMQP. The length of the rectangle LMQP is the sum of the lengths of KL and LM, which are equal because KLMN is a parallelogram, so LQ = KL + LM = 2 [tex]\times KL \)[/tex]. The width of the rectangle LMQP remains the same as the width of the parallelogram, which is the length of KM, so LP = KM. Therefore, the dimensions of rectangle LMQP are [tex]\( 2 \times KL \)[/tex] by [tex]\( KM \).[/tex]

C. Older soils usually have fewer horizons than younger soils.
D. Their properties are affected by the type of rock from which they form.
E. Their development is affected by climate and organisms.
Answer:
Option C, Older soils usually have fewer horizons than younger soils.
Explanation:
Older soils have well expressed soil horizons it is because old soil consists of distinctive layer of deposits including both organic and inorganic material which undergo stratification with time. The longer the time duration, the better stratified the soil is and hence more clear and distinctive are its horizons.
However in case of new soil, the horizon is not distinctive because of incomplete stratification.

Which agent of erosion causes the sandblasting of bedrock
Answer:
Wind
Explanation:
Wind is an agent of erosion which causes the sandblasting of bedrock. Sandblasting is a stream of sand projected by compressed air. It is a high velocity blast of air or steam carrying sand to etch glass or to clean stone or metal surfaces.
In response to rising atmospheric conditions, wind is caused by the movement of gas molecules in the Earth's atmosphere. The winds act like a pneumatic scouring agent and the top layer of fine soil is dislodged and transferred to undesirable places as a result.
Answer:
Wind
Explanation:
Which agent of erosion causes the sandblasting of bedrock
glaciers

Gravity, water, wind, and glacier are things that can erode material
Sandblasting is process of smoothing and cleaning a hard surface by forcing solid particles across that surface at high speeds using compressed air and is the most common method used for surface preparation; they can occur naturally, usually as a result of particles blown by wind causing aeolian erosion, or artificially
The side of the moon that faces the sun is always illuminated, but that side does not always face Earth. The different phases of the moon are caused by the moon's near 28-day _____.
The phases of the moon are caused by a lunar cycle, a nearly 28-day cycle that the moon takes to orbit the earth. The changing angle of the Sun's illumination on the Moon's surface as it orbits the earth is what results in the changing phases of the moon that we see from earth.
Explanation:The moon's phases that we observe from Earth are dictated by the Moon's near 28-day cycle called the lunar cycle. This cycle is the period it takes for the moon to orbit the Earth, also known as its period of revolution. Since the Moon's period of revolution is equal to its period of rotation, it always keeps the same face towards Earth. The changing angle of the Sun's illumination on the Moon because of this revolution gives us the changing Moon phases.
During the lunar cycle, we see different amounts of the Moon's illuminated side. For example, during the full moon phase, the side of the Moon facing the Earth is fully illuminated by the Sun and is thus completely visible. At new moon, the Moon is between the Earth and the Sun, and the side of the Moon facing the Earth is not visible to us because it is not illuminated by the Sun. The gradually increasing and decreasing illumination of the Moon as seen from Earth is what causes the difference in appearance of the Moon's phases.
