Why is there a tsunami warning system in the Pacific Ocean but not in the Atlantic or Indian Oceans?
Select one:
a.
This question states false information. There is in fact a tsunami warning system in all three of the oceans.
b.
The Pacific has a tsunami warning system that can detect earthquake-induced tsunamis in all three oceans, so there is no need for a separate system in all three oceans.
c.
The Pacific Ocean is surrounded by the "Ring of Fire", numerous volcanoes and earthquakes along the edges of the ocean basin due to convergent and transform plate boundaries existing there, making the risk of large earthquake-triggered tsunamis there high. The Indian Ocean has fewer convergent boundaries and the Atlantic has none.
d.
There was first a tsunami warning system placed in the Atlantic Ocean, where the risk of earthquake-induced tsunamis is highest, but we failed to continue to allocate funding for the maintenance and the system is now non-functional.
Answer: awnser c
Explanation: that is true because the pacific ocean is the ring of fire and volcanoes mak earth quakes because theocean plate pushes and makes a humongus wave.

Explanation:
Calculate the average change in soil moisture over the summer (period of data). Assume no loss or gain from/to deep groundwater. Solve the water balance for the change in soil moisture storage. What is the soil moisture storage at the end of the summer (in mm)? Did watershed storage increase or decrease (that is, what is the sign of delta S (positive or negative)?
Hint: Make sure that all water balance components are in the same unit. One way to solve this would be to convert all measurements to units of meter (m for length, m2 for area, m3 for volume) for the calculation, and then only at the very end convert to mm.
• Watershed area = 7 ha
• Precipitation = 12 in
• Estimated evapotranspiration (ET) from a weather station = 17 cm
• Average soil profile moisture storage at beginning of summer = 20 cm
Discharge from the watershed = 11,000 m3
To calculate the average change in soil moisture over the summer, we need to consider the water balance components. The water balance equation can be written as follows:
Change in Soil Moisture Storage = Precipitation - Evapotranspiration - Discharge
First, let's convert the given measurements to the same unit (meters):
Watershed area = 7 hectares = 70,000 m²
Precipitation = 12 inches = 0.3048 meters
Estimated evapotranspiration (ET) = 17 centimeters = 0.17 meters
Average soil profile moisture storage at the beginning of summer = 20 centimeters = 0.2 meters
Discharge from the watershed = 11,000 cubic meters
Now, let's substitute the values into the water balance equation:
Change in Soil Moisture Storage = 0.3048 m - 0.17 m - 11,000 m³ / 70,000 m²
Change in Soil Moisture Storage = -0.8652 m - 11,000 m³ / 70,000 m²
Change in Soil Moisture Storage = -0.8652 m - 0.1571 m
Change in Soil Moisture Storage = -1.0223 m
Since the result is in meters, we need to convert it to millimeters (mm):
Change in Soil Moisture Storage = -1.0223 m * 1000 = -1022.3 mm
The negative sign indicates a decrease in soil moisture storage. To find the soil moisture storage at the end of summer, we subtract the change from the initial storage:
Soil Moisture Storage at the end of summer = 0.2 m - 1.0223 m = -0.8223 m
Finally, converting it to millimeters:
Soil Moisture Storage at the end of summer = -0.8223 m * 1000 = -822.3 mm
Therefore, the soil moisture storage at the end of the summer is approximately -822.3 mm. The negative sign indicates a decrease in soil moisture storage.

How does sediment tend to settle in a stream channel, or in a lake, or in a desert environment? What role does energy play in the settlement of sediment?
In a stream channel, sediment tends to settle based on the energy level of the flowing water. Higher energy levels, such as during periods of increased flow or steep gradients, allow larger and heavier sediment particles to remain suspended in the water column or be transported downstream.
As the energy decreases, smaller and lighter particles begin to settle. Coarser sediment, such as gravel and sand, tends to settle first, followed by finer particles like silt and clay.
In a lake, sedimentation occurs when the energy of the water decreases significantly, allowing particles to settle to the lake bottom. The settling process is influenced by factors such as water velocity, turbulence, and the size and density of the sediment particles. Coarser sediment often accumulates near the lake's inlet or along the shoreline, while finer particles may distribute more evenly throughout the lake.
In a desert environment, sediment settles through a process known as deposition. Wind plays a crucial role in carrying and transporting fine-grained sediment particles, such as sand and dust, across the landscape. When the wind speed decreases or encounters an obstruction like vegetation or topographic features, the sediment particles lose their energy and settle out of the air, forming dunes or accumulating as windblown deposits.
Energy plays a critical role in the settlement of sediment in all these environments. Higher energy levels, such as fast-flowing water or strong winds, keep sediment particles suspended or in motion. As the energy decreases, particles lose their ability to remain in suspension or be transported and settle due to gravity. Understanding the energy dynamics within each environment helps explain how sediment deposition and settlement occur in relation to water flow or wind speed.

In your own words, what is the Theory of Plate Tectonics and why is it important?
How does this idea help you to understand how oceans work?
The Theory of Plate Tectonics is a scientific theory that describes the movement of large plates of the Earth's lithosphere and the processes that occur as they interact with one another. The theory states that the Earth's lithosphere is broken up into plates that move around and interact with one another.
The Theory of Plate Tectonics is significant because it explains the movement of the Earth's continents, the formation of mountains, earthquakes, and volcanoes. It is also important in understanding the distribution of natural resources, such as minerals and oil. By knowing the processes that occur in the Earth's lithosphere, we can understand how these resources are formed and where they are likely to be found.
The Theory of Plate Tectonics helps us understand how oceans work by explaining the formation and movement of the oceanic crust. The theory states that new oceanic crust is formed at mid-ocean ridges, where magma rises up from the mantle and cools to form new crust. This process is known as seafloor spreading. As the new crust is formed, it pushes the existing crust away from the ridge, creating a spreading zone. This spreading zone is where the ocean floor is spreading apart, and new crust is being created.
The theory also explains the process of subduction, where one plate is pushed beneath another plate. This process occurs at subduction zones, where oceanic crust meets continental crust or another oceanic plate. As the oceanic crust is pushed beneath the other plate, it melts and forms magma, which can rise up to the surface to form volcanoes.

Which of the following tectonic settings is necessary to form a volcanic island arc?
a. Continental rift zone
b. Mid-oceanic ridge zone
c. Subduction zone between an oceanic and a continental plate
d. Subduction zone between two oceanic plates
A volcanic island arc is formed due to the subduction zone between an oceanic and a continental plate. The correct option is C.
Subduction zone between an oceanic and a continental plate. A volcanic island arc is a series of volcanic islands formed parallel to a continent's edge. They are formed as a result of the subduction of an oceanic plate beneath a continental plate. Volcanic island arcs are the results of convergent plate boundaries where two plates converge, one of which is an oceanic plate.
The subduction of an oceanic plate beneath the continental plate causes magma to form in the mantle wedge. As a result, the magma forms a volcanic arc of islands behind the subduction zone.
Volcanic island arcs are most commonly found in the Pacific Ocean, where the Pacific Plate converges with several smaller plates and subducts beneath them. The correct option is C.
