kilaunea is not as explosive as the eruption of mt st helens. what is the overall control that dictates this differnecec
Kilauea is not as explosive as the eruption of Mt. St. Helens due to the difference in magma viscosity and gas content. The overall control that dictates this difference is magma composition and gas content.
The magma composition of Kilauea is primarily basaltic, which has a low viscosity, and gas content is less than that of Mt. St. Helens. Due to these properties, the lava can flow easily and doesn't create any blockages or blockage pressure. Hence, the eruption is effusive and not explosive. The effusive eruption leads to slow-moving lava flows that do not have the potential to be very destructive.
On the other hand, Mt. St. Helens has an andesitic composition, which has a higher viscosity and more gas content. It leads to the creation of blockages within the vent of the volcano, which ultimately leads to an explosive eruption. When the pressure built up inside the vent due to the blockage, it eventually led to an explosive eruption.
The difference in the viscosity of magma, and gas content is an overall control that dictates the difference between the two volcanoes' eruption. Therefore, it is concluded that the difference in magma composition and gas content is responsible for the difference in the explosiveness of Kilauea and Mt. St. Helens' eruption.

why might this be? (hint: what processes in both living and dead trees produce co2 ?) tropical rain forests also produce co2 due to living trees' respiration and decomposition of dead trees. due to this fact, relative consumption of co2 is not as great as has been expected.
Tropical rain forests produce CO2 due to both the respiration of living trees and the decomposition of dead trees. This leads to a lower relative consumption of CO2 than is expected.
Both living and dead trees contribute to the production of carbon dioxide (CO2) through respiration and decomposition processes. Living trees release CO2 through cellular respiration, which is the process by which they use oxygen to convert sugars into energy. Dead trees also release CO2 as they decompose, either through the action of microorganisms or through physical processes like wind and erosion.
While it's true that tropical rainforests produce CO2 through respiration and decomposition, they also play an important role in removing CO2 from the atmosphere through photosynthesis. Trees absorb CO2 from the air and use it to build their cells and grow, releasing oxygen as a byproduct. This process helps to offset the CO2 produced by other sources, such as human activities.
However, the extent to which tropical rainforests are able to absorb and sequester CO2 depends on a variety of factors, including the density and diversity of the forest, the health of the trees, and the availability of nutrients and water. Additionally, deforestation and other human activities that destroy or disrupt rainforest ecosystems can greatly reduce their ability to act as carbon sinks.

E. Explain ONE challenge a representative might face in connecting with rural constituents as
compared with constituents in urban areas.
Answer:
One challenge a representative might face in connecting with rural constituents as compared with constituents in urban areas is the issue of geographic distance. Rural areas are often more spread out and have lower population densities than urban areas, which can make it more difficult for representatives to physically reach their constituents. This can make it harder for representatives to hold town hall meetings, attend community events, and meet with constituents one-on-one. Additionally, rural areas may have limited access to technology and internet connectivity, which can make it harder for representatives to communicate with their constituents through email, social media, and other digital channels. As a result, representatives may need to be more creative in finding ways to connect with their rural constituents, such as holding virtual town hall meetings or partnering with local organizations to reach out to rural communities.

Chemical reactions in the water and aliens are not significant sources of sediment on the continental shelf. The correct option is d.
Most sediment on the continental shelf is derived from erosion on the continent.
What is the continental shelf?The shallow oceanic area is known as the continental shelf.
It is located next to the shore and extends from the shore to the continental slope.
The water depth in the continental shelf ranges from 100 meters to 200 meters, depending on the location, and the slope of the shelf ranges from 0.1 to 1 degree.
The main source of sediment on the continental shelf is erosion on the continent.
When rocks and soil are exposed to the elements, such as wind, rain, and temperature fluctuations, they begin to erode.
This can result in sediment that is transported by rivers to the ocean and deposited on the continental shelf.
Other sources of sediment on the continental shelf include volcanic eruptions, underwater landslides, and other natural events.
Life in the sea is also a source of sediment, as organisms such as corals and clams produce shells and other materials that eventually break down and contribute to the sediment on the sea floor.
