Hoover Dam is the largest dam in the United States, built on the Colorado River to supply hydroelectric power and flood control. Which of the following best describes a downstream environmental effect of Hoover Dam on the Colorado River watershed?
The damming of the Colorado River led to a change in stream flow, preventing river water and sediments from reaching the delta area.

Answers

Answer 1

Answer:

The best description of a downstream environmental effect of Hoover Dam on the Colorado River watershed is that the damming of the Colorado River led to a change in stream flow, preventing river water and sediments from reaching the delta area. This is because the dam blocks the flow of water and captures sediment, which would have continued downstream and been deposited in the delta area to create rich soil and support aquatic and bird life. Without the regular input of fresh water and sediment, the delta area has become increasingly dry and barren, impacting the local ecosystem and economy.

the map of world average annual temperature range shows ________ to have the greatest range.

Answers

The map of world average annual temperature range shows Siberia to have the greatest range.

Siberia, located in northern Russia, experiences extreme temperature variations throughout the year due to its high latitude and continental climate. The temperature ranges from extremely cold winters, with average lows reaching -40 degrees Celsius (-40 degrees Fahrenheit), to relatively warm summers, with average highs reaching 20 degrees Celsius (68 degrees Fahrenheit). These extreme temperature variations result from Siberia's distance from moderating oceanic influences, allowing for large fluctuations between seasons.

Additionally, the region's position in the Earth's high latitudes means it receives less sunlight during the winter months, contributing to the frigid temperatures. In contrast, during summer, the region receives more sunlight, leading to warmer conditions. Overall, Siberia's location and climate characteristics result in the greatest annual temperature range on the world map.

after all inorganic carbon processes (precipitation, silicate and carbonate rock weathering, diffusion, deposition, metamorphosis), how is carbon released to the atmosphere?

Answers

After inorganic carbon processes, carbon can be released into the atmosphere through several natural and human-induced mechanisms.

The main ways carbon is released are:

Volcanic activity:

During volcanic eruptions, other gases such as carbon dioxide (CO2) and methane (CH4) are released into the atmosphere. This process contributes to the carbon cycle by releasing carbon previously stored in rocks and minerals.

Decaying organic matter:

When organic matter such as dead plants and animals decomposes, it undergoes a process called putrefaction. During decomposition, organic carbon is broken down by microorganisms, releasing carbon dioxide as a by-product. It occurs in natural environments such as forests, wetlands, and soils. Breathe:

Organisms such as plants, animals, and microorganisms breathe, consume oxygen, and release carbon dioxide as a metabolic byproduct. This process contributes to the carbon cycle, as carbon continually cycles between the atmosphere and organisms.

combustion:

Burning fossil fuels such as coal, oil and natural gas releases carbon dioxide into the atmosphere. This combustion process is the main source of anthropogenic (man-made) carbon dioxide emissions. In addition, forest fires and biomass burning also release carbon stored in plants into the atmosphere.

The moon does not fall to earth because: The moon is beyond the main pull of Earth's gravity. The moon is pulled by the sun and planets as well as by Earth. The gravitational force provides the required centripetal force for the moon to have its tangential speed around the Earth. The net force on the moon is zero. The moon is in earth's gravitational field.

Answers

The moon doesn't die down since the earth applies gravity opposite to the heading of the speed of the moon. so this power produces centripetal acc and the moon moves in a roundabout circle around the earth.

Gravitaional force = mass of moon x centripetal acc.

GMm/R^2 = mv^2/R

in this way, the moon is into a fixed circle of span R.

The moon rotates around the earth likewise however because of the speed with which the moon got snared onto the world's gravity holds it back from falling onto the earth. This keeps the moon in a pompous circle around the earth even though it is creating some distance from our planet.

Bad physics refers to the incorrect or unrealistic depiction of the laws of physics in a movie, TV show, or other media. This can lead to a lack of accuracy and credibility in the portrayal of scientific concepts, which can be misleading to viewers.

In the scene described in the question, the small car-sized ice chunks would not be able to drop downward through the water due to the buoyancy and pressure of the water, and would instead float upwards towards the surface of the water.

Also, the bouncing of the chunks off the hull of the submarine is unlikely, as the Seaview's hull is designed to deflect water and not bounce objects. Therefore, this is an example of bad physics.

Question 1 of 10What is the measure of JK?A. 1250B. 35C. 145D. 550

Answers

Answer:

A. 125°

Explanation:

Based on the angles of intersecting chord theorem, we have:

90° = ½(measure of arc NM + measure of arc JK)

Arc NM = 55°

Arc JK = ??

Plug in the value into the equation.

90° = ½(55 + JK)

Multiply both sides by 2

2*90 = 55 + JK

180 = 55 + JK

Subtract 55 from each side

180 - 55 = JK

125° = JK

JK = 125°

1. what are the two basic features of a fault and how would you differentiate between them?

Answers

The two basic features of a fault are hanging and footwall. The hanging wall is the upper side of the fault plane while the footwall is the lower side of the fault plane. The hanging wall moves downward and the footwall moves upward. The surface of the Earth is covered by a network of large cracks known as faults.

The earth's crust is in motion, which causes pressure to accumulate on the rocks, and this leads to the development of cracks that may result in earthquakes. Faults occur when rocks are subjected to a lot of pressure and break, forming a fracture or crack that separates the rocks. A fault occurs when two large blocks of the earth's crust shift position relative to one another. The movement of the rocks, as well as the direction in which they move, determine the type of fault. There are two types of faults based on their motion, namely, normal faults and reverse faults. A normal fault is characterized by the hanging wall moving downward relative to the footwall. The hanging wall is the block of rock that lies above the fault plane, while the footwall is the block of rock that lies below the fault plane. When the stress that created the fault is greater than the friction holding the rocks together, the rocks break apart, causing the hanging wall to move downward relative to the footwall.

On the other hand, reverse faults occur when the hanging wall moves upward relative to the footwall. Reverse faults are also called thrust faults, and they occur when rocks are under compression, and the hanging wall moves up. The hanging wall is usually moved up over the footwall. The reverse fault has an angle that is steeper than 45°.

In conclusion, the two basic features of a fault are hanging and footwall. The hanging wall is the upper side of the fault plane while the footwall is the lower side of the fault plane. The hanging wall moves downward and the footwall moves upward. Faults occur when rocks are subjected to a lot of pressure and break, forming a fracture or crack that separates the rocks.

The x-ray emission from a neutron star in a binary system comes mainly from:

The x-ray emission from a neutron star in a binary system mainly comes from the accretion of material from its companion star. Here's a step-by-step explanation:

1. In a binary system, a neutron star is paired with a companion star, which can be either a main-sequence star or a giant star.
2. Due to the strong gravitational pull of the neutron star, it starts to draw material away from its companion star.
3. This material forms an accretion disk around the neutron star, which consists of gas and plasma.
4. As the material in the accretion disk spirals closer to the neutron star, it gets heated up and compressed due to the strong gravitational field.
5. When the material reaches a high enough temperature, it emits x-ray radiation, which is observed as x-ray emission from the neutron star.

So, the x-ray emission from a neutron star in a binary system mainly comes from the accretion of material from its companion star and the subsequent heating and compression of that material.
