An igneous pegmatite indicates that b. the rock cooled slowly and then quickly

Pegmatite is a type of igneous rock that forms when magma cools slowly at first, allowing for the growth of large mineral crystals. After that initial slow cooling, the remaining magma cools more quickly, resulting in a mix of large and small crystals. This combination of cooling rates gives pegmatite its distinctive texture and composition.

Pegmatite can contain a wide variety of minerals, including rare and valuable minerals such as lithium, tantalum, and beryllium. Pegmatite deposits are an important source of these minerals and are mined for their economic value.

Pegmatite can provide important information about the conditions under which it formed, including the composition of the magma and the rate of cooling. The presence of certain minerals in pegmatite can also provide information about the geological history of the area in which it is found.

Answer:

When you cross a boundary line between two regions, you will have left one region and entered another. The boundary line is typically a curve or a line that separates the two regions. You can identify the boundary line by looking at the equation of the function that defines the regions. The boundary line will be the set of points where the equation is true for both regions. For example, if the equation is y = x² and the two regions are above and below the x-axis, then the boundary line is the x-axis itself, since it is the set of points where y = 0 for both regions. When you cross the x-axis, you will have left one region and entered the other.

Explanation:

The avalanche caused by the collapse of Mount St. Helen's bulge also led to a tremendous blast of magma and groundwater when the immense pressure within the volcano was suddenly released.

This pressure had been building for weeks prior to the eruption, as magma had been rising to the surface and creating a large bulge on the side of the mountain. When the bulge finally collapsed, it triggered a massive avalanche of rock, ice, and debris that traveled at speeds up to 150 miles per hour and devastated everything in its path. As the avalanche roared down the mountain, it also triggered a massive explosion of magma and steam that shot high into the sky. This explosion was caused by the sudden release of pressure within the volcano, which allowed the magma and groundwater to mix and create a highly pressurized gas that erupted violently. The resulting blast was heard for hundreds of miles and created a massive ash cloud that spread across the region, causing widespread damage and disruption. In conclusion, the collapse of Mount St. Helen's bulge caused not only an avalanche but also a tremendous blast of magma and groundwater due to the release of pressure within the volcano. The resulting eruption was one of the most significant volcanic events in modern history and had a lasting impact on the landscape and environment of the surrounding area.

False. A mineral can only scratch minerals that are softer than itself on the Mohs scale of mineral hardness. The Mohs scale ranks minerals from 1 (softest) to 10 (hardest).

For example, a mineral with a hardness of 7 can scratch minerals with a hardness of 6 or lower, but it cannot scratch minerals with a hardness of 8 or higher. This is because the harder mineral has stronger bonds between its atoms, making it more difficult to break or scratch. However, it is important to note that the Mohs scale is not a linear scale and the difference in hardness between each mineral may not be equal. Therefore, it is possible for a mineral to scratch another mineral with a slightly higher hardness, but it is not a general rule.

Hot, thin, runny lava flows with low silica content are typically basaltic. Basaltic lava is characterized by its low viscosity, which allows it to flow easily and spread out over long distances.

This type of lava typically erupts from shield volcanoes, which have gentle slopes and are formed by repeated basaltic eruptions. Rhyolitic lava, on the other hand, is thick and viscous, with a high silica content. This type of lava forms explosive eruptions and can create pyroclastic flows, which are fast-moving clouds of hot gas, ash, and rock fragments.

Andesitic lava has an intermediate composition between basaltic and rhyolitic lava, and is typically associated with stratovolcanoes, which have steep slopes and are formed by alternating layers of lava and pyroclastic deposits.

Pyroclastic materials refer to any fragments of rock ejected from a volcano, including ash, pumice, and volcanic bombs.
