Friction forces are caused by the difference in atmospheric pressure from one location to another.

When there is a difference in pressure between two surfaces, such as the ground and an object on it, the resulting force is called friction. This force resists motion and is affected by factors such as the texture and weight of the objects, as well as the nature of the surfaces.

The amount of friction can be increased or decreased by changing the force pushing the surfaces together or by altering the angle of the surfaces. While wind and the earth's rotation can affect atmospheric pressure and indirectly impact friction forces, they are not direct causes.

The given statement "It takes less energy to activate an old fault than to create a comparably sized new one, so old faults must still be treated as areas of weakness vulnerable to earthquakes" is true because old faults are considered areas of weakness in the Earth's crust, and they can still be vulnerable to earthquakes despite being inactive for long periods.

While it takes less energy to activate an old fault compared to creating a new one, the potential impact of an earthquake on a populated area is significant. Even though the fault may not have ruptured in hundreds or thousands of years, the tectonic stresses that have built up over that time can still trigger a sudden movement and cause an earthquake.

As such, it is important to treat old faults as areas of potential seismic hazards and to incorporate this information into building codes and land-use planning in order to minimize the risks associated with earthquakes.

Mechanical weathering is the physical breakdown of rocks into smaller fragments without changing their chemical composition. There are different types of mechanical weathering, including frost wedging, exfoliation, thermal expansion and contraction, biological activity, and abrasion.

Frost wedging occurs when water seeps into the cracks of rocks and freezes, causing the water to expand and crack the rock. Exfoliation is the process of concentric slabs of rock breaking loose in reaction to the unloading of pressure.

Thermal expansion and contraction occur when rocks experience temperature changes, leading to cracks and breakage. Biological activity refers to the actions of plants and animals that can cause mechanical weathering, such as roots growing into rocks and expanding, or burrowing animals causing rocks to break apart.

Abrasion occurs when rocks rub against each other, causing them to wear down over time. Mechanical weathering is a slow process, but it is an important component in the overall process of weathering, which ultimately leads to the breakdown and erosion of rocks.

Wegener's theory of continental drift suggests that the continents were once joined together in a single landmass and have since drifted apart.

To prove this theory, Wegener would need to gather various types of evidence. First, he could study the similarities in rock formations and geological structures on different continents, which would indicate they were once connected. For example, the Appalachian Mountains in North America and the Caledonian Mountains in Europe share striking resemblances.

Second, Wegener could examine fossil evidence of plants and animals found on separate continents, suggesting a common origin. The discovery of the same species or closely related species on distant landmasses, such as the Mesosaurus reptile in South America and Africa, would support his theory.

Third, he could look at the distribution of ancient climate indicators like glacial deposits or coal deposits, which would reveal past climate patterns that align with the idea of continental drift.

Finally, Wegener could study the puzzle-like fit of the continental coastlines, such as the way South America and Africa appear to fit together. This observation, combined with the other evidence, would provide strong support for the theory of continental drift. Overall, by collecting and analyzing these different types of evidence, Wegener could build a convincing case for his groundbreaking theory.

The type of fog that would typically form after a clear night, especially over moist ground, is called radiation fog.

When the ground rapidly cools at night, it cools the air directly above it, resulting in radiation fog. This raises the temperature of the air to its dew point, at which point water vapour in the air condenses into small water droplets, generating fog. Radiation fog is most common in the autumn and winter, when the nights are longer and the temperatures are lower.

When cold air moves over a warm, moist surface, the moisture evaporates into the air, causing the air to reach its dew point temperature and fog to form. When warm, moist air moves over a cooler surface, the air cools and reaches its dew point temperature, resulting in the formation of fog.

Tarn lakes are often associated with cirque basins in high, mountainous terrain.

The correct option is (c).

A cirque basin is a bowl-shaped depression that is formed by glacial erosion and surrounded by steep walls or cliffs. When the glacier melts, it leaves behind a small lake called a tarn in the basin. Tarn lakes are often found in cirque basins because these basins are shaped like bowls that can collect water, and they are typically located in high mountainous regions where glacial activity is common. As glaciers move and erode the surrounding rock, they create these depressions which can fill with water as the glacier melts. The water in tarn lakes is often clear and cold, and they may provide important habitats for various aquatic species.

The elastic rebound theory for the origin of earthquakes was first proposed by Reid following the 1906 San Francisco earthquake.

The elastic rebound theory suggests that before an earthquake, tectonic plates are stuck together due to friction. As stress builds up, the plates deform and store energy like a spring. Eventually, the stress becomes too much for the plates to bear, and they suddenly slip, releasing the stored energy in the form of seismic waves. The theory was first proposed by Harry Fielding Reid, an American seismologist, after studying the San Francisco earthquake of 1906.

He noticed that the ground had shifted along the San Andreas Fault and proposed that the earthquake was caused by the sudden release of stored energy.Harry Fielding Reid, an American geophysicist, first proposed the elastic rebound theory in 1910 after studying the aftermath of the 1906 San Francisco earthquake.

The given statement " How fast air pressure decreases as you increase in altitude does not happen at a constant rate." is false because The Air pressure decreases with altitude because there is less air above pushing down on the air below.

The rate of decrease, however, is not constant, and it can vary depending on several factors such as temperature, humidity, and weather patterns. In general, air pressure decreases more rapidly at lower altitudes and more slowly at higher altitudes.At sea level, air pressure is highest and decreases rapidly as altitude increases.

However, as altitude increases, the air becomes less dense and the rate of pressure decrease slows down. At around 18,000 feet, the pressure has decreased to about half of what it is at sea level.

In the United States, tornado activity is most common during the spring and early summer months, from March to July.

This is because during this time, there are large temperature contrasts between warm, moist air from the Gulf of Mexico and cooler air from the north. These temperature contrasts can create powerful thunderstorms, which can in turn spawn tornadoes.

In addition to temperature contrasts, other weather factors also play a role in tornado formation. For example, wind shear (the change in wind speed and direction with height) and atmospheric instability (the tendency for the atmosphere to overturn) can both contribute to the development of thunderstorms and tornadoes. While tornadoes can occur at any time of the year, the most favorable conditions for tornado formation tend to be present in the spring and early summer months.

An oceanic hotspot volcano is formed when magma rises up from deep within the Earth's mantle and melts through the oceanic crust.

This process occurs at a point where the Earth's mantle is unusually hot and the magma rises up to form a volcano. The stages of formation of an oceanic hotspot volcano from the submarine stage to the seamount stage are as follows:
1. Submarine Stage: This is the first stage of formation where the magma rises up from the mantle and creates a submarine volcano that is located below the surface of the ocean. This stage is characterized by continuous eruption of lava, and the formation of a conical shape of the volcano.
2. Shallow Water Stage: This stage is characterized by the emergence of the volcano from below the ocean's surface, but the top of the volcano is still underwater. At this stage, the volcano begins to create a ring-shaped reef around it, and the eruption of lava continues.
3. Emergent Stage: At this stage, the volcano has completely emerged from the ocean's surface and forms an island. The volcano continues to erupt lava and expand its size.
4. Seamount Stage: This is the final stage of formation where the volcano has stopped erupting, and it begins to erode over time, leaving behind a seamount. This stage marks the end of the volcano's active lifecycle.
In summary, the stages of formation of an oceanic hotspot volcano from the submarine stage to the seamount stage are submarine stage, shallow water stage, emergent stage, and seamount stage.

True. The eruption of rhyolitic lava generally creates a steep feature called a lava dome. Rhyolitic lava is highly viscous and has a high silica content, which means that it doesn't flow as easily as other types of lava. Instead, it tends to pile up around the vent, forming a steep-sided dome-shaped feature.

These domes can grow to be hundreds of meters high and can be quite unstable, as the lava can continue to push up from underneath and cause the dome to collapse or explode. Lava domes are often associated with explosive volcanic eruptions, as the pressure builds up within the magma chamber and eventually blows off the top of the volcano. The resulting eruption can be highly destructive, with ash and debris raining down on the surrounding area. However, not all eruptions of rhyolitic lava are explosive - some are relatively quiet and produce slow-moving lava flows. Regardless of the type of eruption, the formation of a lava dome is a characteristic feature of rhyolitic volcanoes and is an important indicator of the type of eruption that has taken place.
