a nebula is called a stellar furnace why
Answer:
Star Forming Nebula
Explanation:
One such stellar nursery is the Orion Nebula, an enormous cloud of gas and dust many light-years across. Turbulence from deep within these clouds creates high density regions called knots. These knots contain sufficient mass that the gas and dust can begin to collapse from gravitational attraction.
the maximum amplitude of a seismic wave from a magnitude 6 earthquake will be how many times greater than that for a magnitude 4 earthquake?
When it comes to the maximum amplitude of a seismic wave from a magnitude 6 earthquake being how many times greater than that for a magnitude 4 earthquake, the answer is 100 times greater.
A seismic wave is a shock wave that is caused by an earthquake. They spread out from the focal point, or hypocenter, of the earthquake's release. These waves, which radiate outward from the hypocenter, spread out in all directions.
Seismic waves are created by tectonic shifts in the Earth's crust, and they are divided into two categories: body waves and surface waves. Body waves move through the Earth's interior, while surface waves are restricted to the surface. Earthquakes are classified by their magnitude, which is calculated using the Richter scale. The Richter scale is a logarithmic scale that quantifies the amount of energy released by an earthquake. Each step on the scale is ten times greater than the previous one.
Magnitude 6 earthquakes release 32 times more energy than magnitude 5 earthquakes. Similarly, magnitude 7 earthquakes release 32 times more energy than magnitude 6 earthquakes. The scale is logarithmic, as previously mentioned, and thus every one-point increase corresponds to a tenfold increase in the amount of energy released.
The amplitude of a seismic wave is directly proportional to the magnitude of the earthquake. Therefore, if the magnitude of an earthquake increases by one point, the amplitude of the seismic wave increases by ten times. As a result, the maximum amplitude of a seismic wave from a magnitude 6 earthquake is 100 times greater than that for a magnitude 4 earthquake.

in addition to increasing the weight of earth and rock material, what is the net effect of water in a landslide? group of answer choices it causes consolidation. it decreases the normal force. it decreases the gravity (g). it causes erosion. it increases the frictional resistance.
The net effect of water in a landslide is that it decreases the frictional resistance, making the slope more unstable and increasing the likelihood of a landslide occurring. Option D is the correct answer.
Water plays a significant role in the occurrence and severity of landslides. When water infiltrates the soil, it increases its weight of the soil, making the slope more prone to failure.
Additionally, water reduces the interlocking of particles in the soil, decreasing its frictional resistance and making it more unstable. Water also acts as a lubricant between the soil layers, making it easier for one layer to slip over another.
This is particularly true when the water pressure in the soil is high due to heavy rainfall or melting snow. Thus, the presence of water can greatly increase the likelihood of a landslide occurring and increase its destructive potential.

What type of sediment load is deposited first when a river enters the ocean? [Select] Which of the following types of sediment are NOT influenced by flow velocity? ✓ [Select] Dissolved Load Suspended Load Bed Load
When a river enters the ocean, the first type of sediment load deposited is suspended load.
Suspended load is the type of sediment that consists of fine particles, such as silt and clay, that are carried along by the river's flow and remain suspended in the water column. As the river's flow slows down upon entering the ocean, these fine particles settle out and are deposited as suspended load.
The type of sediment load that is NOT influenced by flow velocity is the dissolved load. Dissolved load consists of minerals and other soluble materials that are dissolved in the water. These materials are not influenced by flow velocity because they are already in a dissolved state and do not need to be carried along by the river's flow.
Only the bed load is influenced by flow velocity as it consists of larger particles, such as sand and gravel, that are transported by rolling, sliding, and bouncing along the river's bed. Therefore, the correct answers are: Suspended Load Dissolved Load

Why do you think Costa Rica has set aside a larger percentage of its land for biodiversity conservation than the United States has? Should the United States reserve more of its land for this purpose? Explain.
"Costa Rica's biodiversity relies largely on its forest while it is not the same thing in the U.S." Costa Rica is in tropical area. U.S should put more effort in preserving forests.
In 2020, a report by two United Nations environmental bodies warned that unless radical and creative action is taken now to conserve the Earth's biodiversity. Many local and regional ecosystems that support human lives are at risk of collapsing.
To reduce deforestation, wide spread removal of forests, the government of Costa Rica has eliminated subsidies for converting forest land to range land. Instead, it pays land owners to maintain or restore tree cover.
Costa Rica is one of the most biodiverse countries in the world and is located in the centre of Central America. It is believed that there are about 500,000 species there, or about 5% of all species on Earth.

Which of the following is not an example of methods used for short-term climate reconstructions? lake core analysis ocean sediment core analysis dendrochronology cave formation (speleothem) analysis carbon isotope analysis
Among the provided options, carbon isotope analysis is not an example of methods used for short-term climate reconstructions.
The other methods mentioned, including lake core analysis, ocean sediment core analysis, dendrochronology, and cave formation (speleothem) analysis, are commonly employed techniques for reconstructing short-term climate variations. Carbon isotope analysis, on the other hand, is typically used to study carbon cycling, sources, and sinks, but it is not a primary method for directly reconstructing short-term climate variations.
Dendrochronology utilizes tree rings to reconstruct past climate conditions, as the width and characteristics of tree rings can provide insights into temperature and precipitation patterns. Cave formation (speleothem) analysis involves studying the growth and composition of mineral deposits in caves, which can offer information about past climate changes.

find the consecutive whole numbers if the sum of the squares of the first three numbers is equel to the sum of squares of the last two numbers
To solve this, let's assume that the consecutive whole numbers are x, x+1, x+2, x+3, and x+4.
According to the given condition, the sum of the squares of the first three numbers is equal to the sum of squares of the last two numbers. Mathematically, this can be expressed as:
x^2 + (x+1)^2 + (x+2)^2 = (x+3)^2 + (x+4)^2
Expanding and simplifying this equation gives:
x^2 + x^2 + 2x + 1 + x^2 + 4x + 4 = x^2 + 6x + 9 + x^2 + 8x + 16
Combining like terms, we have:
3x^2 + 6x + 5 = 2x^2 + 14x + 25
Simplifying further, we get:
x^2 - 8x + 20 = 0
Now, we can solve this quadratic equation using factoring or the quadratic formula to find the values of x. Once we find the value of x, we can determine the consecutive whole numbers by adding x+1, x+2, x+3, and x+4.
By solving the quadratic equation x^2 - 8x + 20 = 0, we can find the value(s) of x which will give us the consecutive whole numbers that satisfy the given condition.

The large body of water in the image above is partially enclosed by land and is larger than a bay. It is best described as
an)
A. gulf
B. river
C. estuary
D. strait
Answer:
The correct answer would be A. gulf.
We can immediately eliminate option B and D, because rivers and straits are normally smaller than bays.
Option C wouldn't make sense either, since an estuary is not an area enclosed by land, but rather an area where streams and rivers flow into a larger body of water, like an ocean.
Ultimately, this gives the correct answer to be A. Gulf.
