Less than 1% of volcano-related deaths are caused by ______ because they move very slowly.

Hawaii is located at an oceanic hot spot tectonic setting. Hence, first hint is correct.

Lithology, chemistry, and preservation of deposit collections in their depocenters, the sedimentary basins, are primarily controlled by the tectonic context. The features that can form along plate tectonic boundaries include deep ocean trenches, volcanoes, island arcs, undersea mountain ranges, and fault lines. A large portion of the intraplate volcanism that is observed in the ocean basins is caused by oceanic hotspots, which are the surface manifestation of rising mantle plumes from the Earth's interior.

An illustration of a hotspot track is the Hawaiian Islands and the chain of seamounts that extends for around 6,000 kilometers (3,750 miles) into the northwest Pacific Ocean. The youngest and most active volcano in the group is on Hawaii Island.

Igneous rocks composition can vary greatly, but generally speaking, they can be classified as either mafic or felsic. Mafic igneous rocks are characterized by their high content of magnesium and iron, and are typically dark-colored and heavy. In contrast, felsic igneous rocks are rich in silica, potassium, and sodium, and are generally lighter in color and weight.

When comparing the composition of igneous rocks to mafic igneous rocks specifically, one key difference is in their silica content. Mafic igneous rocks have a lower silica content compared to other igneous rocks, which can affect their physical and chemical properties. For example, mafic igneous rocks tend to be more dense and have higher melting points than felsic igneous rocks due to their composition. Additionally, mafic igneous rocks tend to have higher concentrations of certain minerals such as olivine, pyroxene, and plagioclase. These minerals can affect the physical and chemical properties of the rock, such as its strength and durability. Overall, the composition of igneous rocks can vary greatly, but understanding the differences between mafic and felsic igneous rocks can help to identify their characteristics and how they may behave in different environments.

Soil in good condition for plant growth will be composed of a balanced combination of organic matter, water, air, and mineral matter.

Soil composition plays a crucial role in plant growth and development. A healthy soil must contain a balanced combination of organic matter, water, air, and mineral matter. The percentage of each component may vary depending on the type of soil and the plants that are being grown.

Organic matter provides essential nutrients and helps to improve soil structure, water holding capacity, and drainage. However, an excess of organic matter can lead to waterlogging and nutrient leaching, which can be detrimental to plant growth. Typically, soil in good condition for plant growth will have between 2-5% organic matter.

Water is also essential for plant growth, and soil that is too dry or too wet can cause problems. Soil in good condition for plant growth will typically contain around 25% water by volume.

Air is critical for root respiration and soil microbial activity. Soil in good condition for plant growth will have between 20-30% pore space filled with air.

Finally, mineral matter provides essential nutrients for plants to grow. Soil in good condition for plant growth will typically contain around 45% mineral matter.

The smaller earthquakes of lesser magnitude that follow a major earthquake are known as aftershocks. When an earthquake occurs, the movement of the earth's crust creates stress changes in the surrounding rock.

Aftershocks are a result of these stress changes, and they can occur minutes, hours, days, or even months after the initial earthquake. They are typically smaller in magnitude than the main shock but can still be felt and can cause additional damage to structures already weakened by the initial earthquake.  Aftershocks can also be dangerous for rescue workers and people in damaged buildings who may be attempting to recover or evacuate. It is important to be prepared for aftershocks and to take appropriate safety measures, such as staying away from damaged buildings and seeking open spaces away from trees and power lines.

The environmental condition reduced on a batholith to generate weathering via sheeting is:
A) Pressure

Sheet joints are fractures that develop in rock due to the release of pressure from overlying layers or due to uplift of the rock mass. Batholiths are large bodies of intrusive igneous rock that are formed from magma that cools and solidifies deep within the Earth's crust. As the magma cools and solidifies, it expands and contracts, causing stress and pressure to build up within the rock. Over time, this pressure can cause the rock to fracture along sheet joints. When the pressure is released, the rock expands and the fractures open up, creating sheets of rock that can peel away from the surface. This process is known as exfoliation or sheeting. Therefore, reducing the pressure on a batholith can lead to the generation of weathering via sheeting.

The United States can be divided into cultural regions based on a variety of factors, including history, geography, language, religion, and cuisine. One common method of dividing the United States into cultural regions is by using the nine regions defined by the Census Bureau: New England, Mid-Atlantic, South Atlantic, East South Central, West South Central, East North Central, West North Central, Mountain, and Pacific. These regions are based on a combination of historical settlement patterns, geographic features, and cultural characteristics. Another method is to use the concept of the "cultural hearth," which refers to the geographic origins of a particular culture or way of life. For example, the concept of the "Western" cultural region is often associated with the frontier and the cowboy way of life, while the "Southern" cultural region is associated with the Civil War and the legacy of slavery.

If there is a thin, dark-colored igneous sill across a valley, we would expect its texture to be fine-grained. This is because igneous rocks form when molten rock or magma cools and solidifies. The texture of igneous rocks depends on the rate of cooling. If the cooling is slow, the crystals have more time to grow, resulting in a coarse-grained texture. However, if the cooling is rapid, the crystals have less time to grow, resulting in a fine-grained texture.

In the case of a thin sill, it is likely that the cooling was relatively rapid, as there was not enough volume of magma to retain heat and cool slowly. As a result, the crystals in the igneous rock would be smaller and the texture would be fine-grained. The dark coloration of the sill suggests that it is composed of mafic minerals such as pyroxene and olivine, which are characteristic of basaltic rocks. These minerals also tend to have a fine-grained texture.

Overall, we would expect a thin, dark-coloured igneous sill across a valley to have a fine-grained texture due to the rapid cooling of the magma that formed it.

All of the statements are true and contribute to how movement is seen along the San Andreas Fault.

The average rate of movement of the North American Plate and the Pacific Plate is around 2 inches per year near the San Andreas Fault. However, displacement events can be much greater than 2 inches, as the plates build up stress over time until they suddenly slip, causing earthquakes. These earthquakes can result in displacement events of several feet or more. Different locations of the fault are displaced at different times, which also contributes to how movement is seen along the San Andreas Fault. The fault is not a single, continuous crack in the Earth's crust, but rather a complex network of faults and fractures. When a displacement event occurs, it typically involves only a portion of the fault, rather than the entire fault length.

Finally, displacement along the fault occurs sporadically, sometimes with many years between each displacement event. This means that while the average rate of movement may be 2 inches per year, this movement is not continuous or uniform over time. Instead, the plates may remain locked in place for years or even decades, until the stress builds up enough to cause a sudden displacement event.

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.
