A nice loamy topsoil has the following concentrations of ions. What would be the % Base Saturation? A13+: 7 cmol/kg soil H: 10 cmolc/kg soil Ca2+ : 6 cmolc/kg soil K+:3 cmol/kg soil Nat : 3 cmol/kg soil Mg2+ : 4 cmol/kg soil Report your answer to the nearest whole number. Enter only numbers, with no words, units, % signs, etc.
The % base saturation of the given loamy topsoil is 48%. This means that almost half of the exchangeable cations in the soil are base cations.
To calculate the % base saturation, we need to first find the total exchangeable cations (TEC), which is the sum of all the cations in the soil.
TEC = A₁₃⁺ + H⁺ + Ca₂⁺ + K⁺ + Na⁺ + Mg₂⁺
TEC = 7 + 10 + 6 + 3 + 3 + 4
TEC = 33 cmolc/kg soil
Next, we need to find the sum of the exchangeable base cations (Ca₂⁺, Mg₂⁺, K⁺, Na⁺).
Sum of exchangeable base cations = Ca₂⁺ + Mg₂⁺ + K⁺ + Na⁺
Sum of exchangeable base cations = 6 + 4 + 3 + 3
Sum of exchangeable base cations = 16 cmolc/kg soil
Finally, we can calculate the % base saturation using the following formula:
% Base Saturation = (Sum of exchangeable base cations / TEC) x 100%
% Base Saturation = (16 / 33) x 100%
% Base Saturation = 48%

on a clear, windy day, the depth to which mixing occurs above the surface depends upon:
The depth to which mixing occurs above the surface on a clear, windy day is influenced by a complex interplay between these factors.
On a clear, windy day, the depth to which mixing occurs above the surface depends on several factors, including:
1. Wind speed: The stronger the wind, the deeper the mixing will be. High wind speeds generate more turbulence, which allows mixing to occur at greater depths.
2. Water temperature: The temperature of the water affects its density, which, in turn, affects the mixing depth. Cooler water is denser than warmer water, so mixing will occur at shallower depths in colder water.
3. Solar radiation: The amount of solar radiation that penetrates the water column influences the mixing depth. If the water is clear, more sunlight can penetrate the water column, which can lead to deeper mixing.
4. Water depth: The depth of the water column affects the extent of mixing. Shallow water bodies will mix more easily than deep water bodies, where mixing is restricted by the weight of the water above.
5. Bottom topography: The shape of the bottom of the body of water can also impact the mixing depth. If the bottom is uneven or contains obstructions, it can create turbulence that leads to deeper mixing.

how does the elevation of the divide compare to the elevation the stream in the adjacent drainage area?
The elevation of the divide is generally higher than the elevation of the stream in the adjacent drainage area.
This is because the water flows downhill due to gravity, so it naturally follows the path of least resistance. When it encounters a high point in the landscape, such as a ridge or mountain range that forms the divide, the water is forced to flow around it and into a different drainage basin.
Therefore, the divide is typically the highest point along the ridge or mountain range, while the adjacent stream will be at a lower elevation downstream from the divide.

On the average, the tropopause is highest above the surface over the ________.
A) North Pole
B) Arctic Circle
C) South Pole
D) Equator
E) Antarctic Circle
On the average, the tropopause is highest above the surface over the equator. n other words, cold conditions lead to a lower tropopause, obviously because of less convection. Deep convection (thunderstorms) in the Intertropical Convergence Zone, or over mid-latitude continents in summer, continuously push the tropopause upwards and as such deepen the troposphere.
This is because thunderstorms mix the tropospheric air at a moist adiabatic lapse rate. In the upper troposphere, this lapse rate is essentially the same as the dry adiabatic rate of 10K/km. So a deepening by 1 km reduces the tropopause temperature by 10K. Therefore, in areas where (or at times when) the tropopause is exceptionally high, the tropopause temperature is also very low, sometimes below -80C. Such low temperatures are not found anywhere else in the Earth's atmosphere, at any level, except in the winter stratosphere over Antarctica. On the other hand, colder regions have a lower tropopause, obviously because convective overturning is limited there, due to the negative radiation balance at the surface. In fact, convection is very rare in polar regions; most of the tropospheric mixing at middle and high latitudes is forced by frontal systems in which uplift is forced rather than spontaneous (convective). This explains the paradox that tropopause temperatures are lowest where the surface temperatures are highest.

in a radio galaxy, the ultimate energy source for the entire radio lobe source is thought to be:
In a radio galaxy, the ultimate energy source for the entire radio lobe source is thought to be the supermassive black hole at the center of the galaxy. Radio galaxies are characterized by their strong and extended emission of radio waves, which are produced by high-energy electrons spiraling around magnetic field lines in the presence of synchrotron radiation.
The source of energy for these high-energy electrons is believed to be the accretion disk surrounding the supermassive black hole. As matter falls towards the black hole, it releases a tremendous amount of gravitational potential energy, which powers the accretion disk and produces intense radiation across the electromagnetic spectrum, including X-rays and gamma rays.
Part of this energy is then channeled into powerful jets of plasma that are launched from the vicinity of the black hole and produce the extended radio emission that characterizes radio galaxies.

deep-ocean and near-bottom currents are strongest along the __________ sides of ocean basins.
Deep-ocean and near-bottom currents are strongest along the western sides of ocean basins.
This phenomenon occurs due to the combination of several factors, including the Coriolis effect, wind patterns, and ocean floor topography.
The Coriolis effect, caused by Earth's rotation, deflects moving objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. As a result, surface water moves away from the western sides of ocean basins, causing deeper water to rise up and replace it, creating strong deep-ocean currents.
Wind patterns also play a role, as the trade winds in the tropics and westerlies in the mid-latitudes help push water towards the western sides of ocean basins. The interaction between these winds and the Coriolis effect causes the formation of boundary currents, which contribute to the strength of deep-ocean currents along the western sides.
Lastly, the ocean floor topography, including the shape and depth of ocean basins, can influence the strength and direction of deep-ocean currents. The western boundaries of ocean basins often have steeper slopes and narrower continental shelves, which lead to more intense near-bottom currents. In summary, the combination of the Coriolis effect, wind patterns, and ocean floor topography results in deep-ocean and near-bottom currents being strongest along the western sides of ocean basins.

the sum of the characteristics that hold a mass in place is referred to as __________.
The sum of the characteristics that hold a mass in place is referred to as Shear resistance.
The overall shear resistance of a mass depends on various factors, including the material's composition, structural design, and external support. Material properties such as strength, stiffness, and ductility play crucial roles in determining shear resistance. Stronger materials exhibit greater resistance to deformation under shear forces, while ductile materials can undergo significant deformation without breaking.
The structural design also influences shear resistance. Geometric properties, such as shape and size, as well as internal reinforcements like steel bars or fibers, can improve a structure's ability to resist shear forces. Properly designed joints and connections between structural elements further enhance shear resistance by distributing forces evenly across the structure.
External support, such as soil or adjacent structures, contributes to a mass's shear resistance as well. For instance, in the case of retaining walls or foundations, the surrounding soil can provide additional support to counteract the shear forces exerted on the mass.
In conclusion, shear resistance is the sum of the characteristics that allow a mass to withstand shear forces. It is dependent on material properties, structural design, and external support, all of which work together to maintain the stability and integrity of the mass under stress.

the ________ is the site of initial rupturing associated with an earthquake.
The focus, or hypocenter, is the site of initial rupturing associated with an earthquake. To understand this concept, let's briefly discuss the process of an earthquake and the terminology involved.
An earthquake is a sudden release of energy in the Earth's crust, causing the ground to shake. This energy release typically occurs along fault lines or fractures in the Earth's crust, where tectonic plates move relative to one another. The process leading to an earthquake involves the following steps:
1. Tectonic plates interact and apply stress on each other, creating strain in the rock layers at and near the fault.
2. As stress builds up, the rocks start to deform, accumulating potential energy.
3. When the stress reaches a critical point, the rock layers rupture, releasing the stored potential energy as seismic waves.
4. These seismic waves travel through the Earth and cause the ground to shake, which we experience as an earthquake.
The focus, or hypocenter, is the exact point in the Earth's crust where the initial rupturing and energy release occurs. It is the origin of the seismic waves that cause the ground shaking. Directly above the focus on the Earth's surface is the epicenter, which is often the location where the shaking is strongest and where the most damage occurs.
In summary, the focus, or hypocenter, is the site of initial rupturing associated with an earthquake. It is where the energy release originates, and the seismic waves travel outward from this point, causing the ground to shake and potentially leading to significant damage.

what is the magnitude of an earthquake that was recorded in the seismograph below, where the highest amplitude wave is 20 mm and the seismometer is 200 km from the epicenter?
To determine the magnitude of an earthquake, we use the Richter scale, which measures the amplitude of the seismic waves. The amplitude is the height of the wave from the baseline to the top. In this case, the highest amplitude wave is 20 mm.
However, to calculate the magnitude, we also need to take into account the distance between the seismometer and the epicenter. The farther away the seismometer is, the lower the amplitude of the waves recorded.
So, to calculate the magnitude, we use the following formula:
Magnitude = log10 (amplitude in mm) + 3log10 (distance in km) - 2.92
Plugging in the values given, we get:
Magnitude = log10 (20) + 3log10 (200) - 2.92
Magnitude = 1.3 + 3.3 - 2.92
Magnitude = 1.68
Therefore, the magnitude of the earthquake recorded on this seismograph is approximately 1.68 on the Richter scale.
