Si (Silica) is found in greater amounts in low viscosity magma, than in high viscosity magma. Option A is correct answer.

High silica content magmas will consequently show higher levels of polymerization and have higher viscosities than magmas with low silica concentration. A substance's viscosity is a measurement of its consistency. A substance's viscosity is defined as its capacity to resist flow. Viscosity is, in some ways, the inverse of fluidity. Because cold molasses is less fluid than water, it has a greater viscosity.

The temperature, composition, and gas concentration of a magma all influence its viscosity. The relationship between temperature and viscosity is self-evident. The greater the temperature, like with most liquids, the more fluid the material becomes, reducing its viscosity.

The source that provides DNA evidence supporting the idea of a coastal migration to the Americas is human fossils.

Studies of DNA extracted from ancient human remains have provided evidence for the coastal migration theory, which posits that the first humans to arrive in the Americas migrated along the Pacific coast of North and South America, rather than through an inland route.

Specifically, mitochondrial DNA studies of ancient human remains found in North and South America have shown genetic links between these populations and modern-day populations in Southeast Asia and the Pacific Islands, suggesting that the first Americans originated from these regions and migrated along the coastal route.

DNA evidence from plant and animal fossils can also provide information about past environments and migrations, but it is the analysis of ancient human DNA that has been most crucial in supporting the coastal migration theory.

When excavating and finding a series of buttons made of shell, the chronometric dating method that would be used to discover their age is Radiocarbon dating.

Radiocarbon dating is an archeological technique that determines the age of carbon-bearing materials up to 60,000 years old. It is used to date organic materials such as wood, charcoal, and bone, as well as inorganic materials like shell and limestone.

Radiocarbon dating, also known as carbon-14 dating, is a method used to determine the age of organic material by measuring the amount of carbon-14 present. It is based on the fact that carbon-14 (14C) is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.

The carbon-14 in the atmosphere combines with oxygen to form carbon dioxide, which is then incorporated into plants through photosynthesis. Animals then eat the plants and consume the carbon-14, and this is how it enters the food chain. When an organism dies, it stops taking in carbon-14, and the carbon-14 that was in the organism begins to decay.

This decay is measured by comparing the amount of carbon-14 to the amount of carbon-12 (12C) in the sample. By comparing the ratio of carbon-14 to carbon-12 in a sample with that of a living organism, it is possible to determine the age of the sample.

Based on the aforementioned explanation, the chronometric dating method that would be used to discover the age of the shell buttons found while excavating is Radiocarbon dating.

Air descends and diverges within high pressure systems is true of high pressure areas.

A high-pressure area or anticyclone is a region where the atmospheric pressure at the surface of the planet is greater than its surrounding atmosphere. The divergence of air as a result of the increased pressure leads to clear skies and pleasant weather. A region of high pressure is also referred to as an anticyclone or high. The wind near the surface of the earth will flow away from the high-pressure region due to the rising motion.

In the high-pressure areas, the sinking motion of the air descends, leading to clear skies and pleasant weather. High-pressure regions have descending air currents that produce stable weather patterns. As the air descends, it heats up, causing the moisture to evaporate and leaving the sky free of clouds. As a result, high-pressure areas are usually associated with good weather. Areas of high pressure tend to be connected with clear, blue skies, as opposed to areas of low pressure, which tend to be linked with cloudy, rainy weather. Hence, the answer to the given question is option D, Air descends and diverges within high pressure systems.

Winds traveling eastward at 60 degrees south would be most impacted by the Coriolis effect. The Coriolis effect is the apparent deflection of moving objects (including winds) when viewed from a rotating reference frame (such as the Earth). The effect is strongest at the poles and decreases towards the equator. At the equator, the Coriolis effect is zero, while at 60 degrees south (a location in the Southern Hemisphere), the effect is quite significant. Therefore, the winds traveling eastward at 60 degrees south would experience a greater deflection due to the Coriolis effect compared to the other options listed. The soccer ball examples are not affected by the Coriolis effect since they are not large enough to experience the effect

The three features to look for when identifying an ancient caldera are a central uplift, a basin-shaped depression, and a breached or modified rim.

To identify an ancient caldera, three specific features to look for are central uplift, a basin-shaped depression, and a breached or modified rim.  Central uplift is the initial formation of a caldera due to the collapse of the magma chamber. This feature is the most visible indicator of a caldera and can be characterized by a central peak or cone-shaped elevation.

The basin-shaped depression of a caldera is caused by subsidence of the ground due to the magma chamber being emptied. This is the defining characteristic of a caldera and can often be seen as a large and circular depression.

Finally, a breached or modified rim can be indicative of an ancient caldera. The breach of the rim is usually caused by the erosional forces of streams and rivers, which can erode the caldera rim and create a terrace along its walls. Additionally, a modified rim can indicate the presence of an ancient caldera, as this can be created by further erosion, faulting, and landslides.
