Environmental possibilism and determinism are theories, put forth in order to comprehend and understand the role played by the physical environmental conditions in the emergence and progress of any human culture or society in a particular location. ScienceStruck explores and lists out the differences between these two concepts.

Explanation:

The calculation of the primary productivity, problems associated with it, and net primary productivity is fundamental in determining photosynthetic efficiency.

Here is a detailed solution to the problem.

In Southeast Asia, the gross productivity of rice is 0.012 grams/cm² day, and the respiration loss is 20%, and one gram of rice is equivalent to 1000 calories.

The insolation energy is 6,000,000 calories/m²/day.

a. To determine the net primary productivity of the rice, we will use the following formula:

Net Primary Productivity = Gross Productivity - Respiration Loss

Net Primary Productivity = 0.012 - (0.20 x 0.012)

Net Primary Productivity = 0.0096 grams/cm² day

To convert to calories/m²/day, we multiply by 1000:

Net Primary Productivity = 0.0096 x 1000

Net Primary Productivity = 9.6 calories/m²/day

The net primary productivity of the rice is 9.6 calories/m²/day.

b. To calculate the efficiency of photosynthesis by the rice, we use the formula below:

Efficiency = (NPP / Insolation Energy) x 100

Efficiency = (9.6 / 6,000,000) x 100

Efficiency = 0.00016 x 100Efficiency = 0.016%

The efficiency of photosynthesis by the rice is 0.016%.

(2) In a Kansas wheat field, the gross productivity of wheat is 0.038 grams/cm² day, and the respiration loss is 22%, and one gram of wheat is equivalent to 850 calories.

The insolation energy is 5,750,000 calories/m²/day.

a. To determine the net primary productivity of the wheat, we will use the following formula:

Net Primary Productivity = Gross Productivity - Respiration Loss

Net Primary Productivity = 0.038 - (0.22 x 0.038)Net Primary Productivity = 0.02964 grams/cm² day

To convert to calories/m²/day, we multiply by 850:

Net Primary Productivity = 0.02964 x 850

Net Primary Productivity = 25.14 calories/m²/day

The net primary productivity of the wheat is 25.14 calories/m²/day.

b. To calculate the efficiency of photosynthesis by the wheat, we use the formula below:

Efficiency = (NPP / Insolation Energy) x 100

Efficiency = (25.14 / 5,750,000) x 100

Efficiency = 0.00043739 x 100

Efficiency = 0.044%

The efficiency of photosynthesis by the wheat is 0.044%.

Star X has an apparent magnitude of 3, and star Y has an apparent magnitude of 8. They compare in observed brightness: C) Star Y is 5 times brighter than star X.

The apparent magnitude of a star is a measure of how bright it appears from Earth. The lower the apparent magnitude, the brighter the star appears. Star X has an apparent magnitude of 3, and star Y has an apparent magnitude of 8.

The apparent magnitude scale is a logarithmic scale used to measure the brightness of celestial objects as observed from Earth. In this scale, lower numbers represent brighter objects.

The difference in apparent magnitude between two stars can be used to determine their relative brightness. The formula to calculate the brightness ratio between two stars based on their apparent magnitudes is: Brightness ratio = 2.512^(m2 - m1)

Therefore, Star X appears brighter than Star Y: C) Star Y is 5 times brighter than star X.

The planets orbit the Sun in the same direction and have nearly circular orbits. This suggests that the solar system formed from a rotating cloud of gas and dust that began to collapse in on itself due to gravity.

Thus, the movements of the planets in the solar system can provide evidence for how the solar system formed. As the material spun faster, it flattened out and eventually formed the planets and their orbits.

The motions of the planets are also affected by the presence of the other planets in the solar system, indicating that the planets formed together rather than separately.

This also explains the reason why the planets closer to the sun are rockier and the planets far away are rather gaseous while spinning the rocky particles might be attracted more strongly. This evidence is consistent with the current understanding of the formation of the solar system.

The reservoir of nutrients in the soil is the largest reservoir of nutrients in the ecosystem.

Nutrients such as nitrogen, phosphorus, and potassium are essential for plant growth and are cycled through the ecosystem as plants are consumed by animals and decompose back into the soil. The soil acts as a reservoir for these nutrients, holding them until they are needed by plants.

This is why maintaining healthy soil is so important for sustaining healthy ecosystems and agriculture. Soil fertility can be maintained by practices such as crop rotation, composting, and minimizing soil erosion.

On May 18, 1980, an earthquake occurred triggering an avalanche that released pressure in the magma chamber. This led to a massive eruption of Mount St. Helens in a lateral blast, which was the most powerful volcanic explosion in the history of the United States. The eruption of Mount St. Helens in May 1980 can be described in the following order:

1. An earthquake occurred: The event began with a magnitude 5.1 earthquake on May 18, 1980, which weakened the north face of the volcano.
2. An avalanche released pressure in the magma chamber: The earthquake triggered a massive landslide and avalanche, causing the removal of a significant portion of the mountain's north face. This, in turn, led to a decrease in pressure within the magma chamber.
3. The volcano erupted in a lateral blast: As the pressure decreased, the volcano erupted in a massive lateral blast, sending a powerful shockwave of hot gases, steam, and rock debris outwards at speeds of up to 300 miles per hour.
4. A pyroclastic flow swept down the mountain: The blast also produced a pyroclastic flow, a dense and fast-moving mixture of hot volcanic gas, ash, and rock fragments. This flow traveled down the mountain and devastated the surrounding landscape.
5. A column of ash rose 25km into the air: Following the lateral blast and pyroclastic flow, a massive column of ash rose approximately 25 kilometers (15.5 miles) into the atmosphere, spreading ash across the Pacific Northwest and causing significant disruption to air travel and local communities.

Stalactites hang from cavern ceilings, while stalagmites form on the floor of caverns.

The two major types of dripstone are stalactites, which hang from cavern ceilings, and stalagmites, which form on the floor of caverns. Stalactites are formed when water containing dissolved minerals drips from the ceiling of a cave. As the water droplets evaporate, they leave behind deposits of minerals, typically calcium carbonate, which gradually build up over time and create elongated formations hanging from the cave ceiling. Stalagmites, on the other hand, form when the mineral-rich water drips onto the cave floor and accumulates to create upward-growing formations.

Stalactites and stalagmites often occur together in cave systems, with stalactites hanging from above and stalagmites rising from the ground. These formations are a result of the slow deposition of minerals over thousands or even millions of years, and they are a fascinating feature of underground caverns.

Due to its extreme coolness and distance from the center compared to earlier stages of star evolution, the surface will appear red. The red giant has a relatively large surface area, which makes it incredibly bright despite its cooler surface temperature.

A star that is nearing death is a red giant. It slowly grew to be many times larger than it was initially. A star may remain on the red giant stage for up to a billion years.

The star will then gradually shrink and cool to become a white dwarf, which is an ultra-dense, Earth-sized star corpse that emits only a small portion of its original energy. After many billions of years, these stars will eventually turn completely cold and stop emitting any energy.

They'll pass away as a so-called "black dwarf," a tiny, scorched-out cinder that is essentially invisible.

Landslides, earthquakes, and tsunamis are all related to the movement and displacement of earth materials.

Landslides occur when soil and rocks on a slope become unstable and slide downhill due to various factors such as excessive rainfall, earthquakes, or human activities. Earthquakes, on the other hand, are caused by the movement of tectonic plates which can result in ground shaking and trigger landslides in unstable slopes. Similarly, tsunamis are triggered by underwater earthquakes that can cause large waves that move inland and lead to coastal erosion, which can also lead to landslides.

All three hazards are interconnected and can cause significant damage to people and infrastructure. They often occur in areas with similar geological characteristics such as mountainous regions, coastal areas, and tectonically active zones. Therefore, it is important to consider the potential for multiple hazards when assessing risk and developing mitigation strategies. It is also important to understand the underlying causes and interactions between these hazards to better prepare for and respond to future events.
