The youngest geologic unit visible in the cross section is the d) conglomerate. Conglomerate is a sedimentary rock that forms when large rounded clasts or pebbles are cemented together by finer sediment or mineral cement.

In geologic time, sedimentary rocks are generally the youngest, as they form from the erosion and deposition of older rocks. Marble, limestone, and granite are all types of rocks, but they are not sedimentary and therefore are unlikely to be the youngest unit in a cross section.

Marble and limestone are metamorphic rocks formed from the recrystallization of calcite-rich rocks like limestone or dolomite. Granite is an igneous rock that forms from the solidification of magma or lava. While all of these rocks can be found in cross sections, conglomerate is the most likely candidate for the youngest unit, as it forms relatively quickly from the erosion and deposition of other rocks.

Yes, xylene is more volatile than trichloroethane (TCA) because it has a benzene ring. This is because benzene rings have a high degree of aromaticity, which makes them highly stable and less reactive.

This means that they have a lower boiling point and higher vapor pressure than TCA, which makes them more volatile. Additionally, the molecular weight of xylene is lower than that of TCA, which also contributes to its higher volatility. The lower molecular weight means that xylene has fewer intermolecular forces holding it together, which allows it to evaporate more easily.

Overall, the combination of the benzene ring and lower molecular weight make xylene more volatile than TCA. This means that it evaporates more quickly and can be more easily inhaled, which makes it important to use proper safety precautions when handling this chemical.

Isostatic movement is a complex geological process influenced by various factors, and multiple factors can interact to shape the coastline. The specific combination and relative significance of these factors can vary depending on the location and local geological conditions.

Isostatic movement of a coastline might occur due to:

1. Changes in the rate of seafloor spreading: This process can affect the elevation of the coastal regions indirectly, as changes in the rate of seafloor spreading can influence the tectonic activity of an area.

2. The removal of a large glacier that rested in that area: When a large glacier melts or retreats, the land beneath it is relieved of the immense weight, which can lead to isostatic rebound, causing the coastline to rise.

3. Uplift related to earthquake activity: Earthquakes caused by tectonic plate movements can lead to uplift or subsidence of the coastline, resulting in isostatic movement.

4. Underwater landslides: These events can change the shape of the seafloor and the distribution of the mass, which may result in a change of isostatic balance along the coastline.

5. Additional seawater: This factor is less likely to cause isostatic movement. However, increased amounts of seawater due to melting ice caps or other sources can cause sea level rise, which may alter the relative position of the coastline.

In summary, isostatic movement of a coastline might occur due to changes in the rate of seafloor spreading, the removal of a large glacier that rested in that area, uplift related to earthquake activity, and underwater landslides. Additional seawater may not directly cause isostatic movement but can alter the relative position of the coastline.

A primary way by which surface waters become groundwater is through a process called infiltration or percolation.

Infiltration refers to the movement of water from the surface into the subsurface, where it becomes groundwater.

When precipitation such as rain or snow falls on the Earth's surface, some of it is absorbed into the ground. The water seeps into the soil and underlying rocks, moving through the pore spaces or fractures in the subsurface materials. This process is influenced by various factors such as soil type, permeability of the rocks, vegetation cover, slope of the land, and precipitation intensity.

As the water infiltrates the ground, it undergoes a series of processes. Initially, it may fill up the pore spaces in the soil and form what is called soil moisture. If the soil becomes saturated, with the pore spaces filled with water, the excess water continues to move downward under the influence of gravity. It percolates through the unsaturated zone, also known as the vadose zone, until it reaches the water table.

The water table is the underground boundary between the saturated zone (where the pore spaces are filled with water) and the unsaturated zone (where the pore spaces contain both air and water). Once the infiltrated water reaches the water table, it becomes part of the groundwater system.

From there, groundwater continues to flow, driven by the force of gravity, along underground pathways such as permeable rock layers, fractures, or porous sediments. It may eventually discharge into springs, streams, lakes, or oceans, completing the hydrological cycle.

It's important to note that not all infiltrated water becomes groundwater. Some of it may be taken up by plant roots, evaporate back into the atmosphere, or contribute to surface runoff and flow directly into rivers or other surface water bodies. The amount of water that becomes groundwater versus surface runoff depends on various factors, including the characteristics of the terrain and the presence of impermeable layers that hinder infiltration.

The thinning of the ozone layer primarily occurs in the Earth's stratosphere, specifically in the region known as the ozone layer. Here are the main factors and locations associated with ozone layer thinning:

Ozone Depletion Substances (ODS): The primary cause of ozone layer thinning is the release of human-made chemicals called ozone-depleting substances (ODS). The most notable ODS are chlorofluorocarbons (CFCs), halons, carbon tetrachloride, and methyl chloroform. These chemicals contain chlorine and bromine atoms, which can destroy ozone molecules in the presence of ultraviolet (UV) radiation.

Polar Regions: The thinning of the ozone layer is most pronounced in the polar regions, particularly over Antarctica (known as the "ozone hole") and to a lesser extent over the Arctic. This phenomenon is attributed to the unique meteorological and climatic conditions in these regions. During winter, the polar stratosphere experiences a phenomenon called a polar vortex, where extremely cold temperatures cause the formation of polar stratospheric clouds. These clouds provide a surface for chemical reactions involving ozone-depleting substances, leading to accelerated ozone depletion.

Stratospheric Circulation: The circulation patterns of the stratosphere play a role in ozone depletion. The equator-to-pole circulation, known as the Brewer-Dobson circulation, transports ozone-depleting substances from lower latitudes to the polar regions. This transport contributes to the thinning of the ozone layer in polar areas.

Sunlight and UV Radiation: The thinning of the ozone layer occurs due to chemical reactions that are triggered by UV radiation from the Sun. UV radiation breaks down ozone molecules, and the presence of ozone-depleting substances enhances this process. Thinning is more likely to occur in regions where UV radiation is higher, such as near the poles and at high altitudes.

It's important to note that international efforts, such as the Montreal Protocol, have been successful in phasing out the production and use of ozone-depleting substances. As a result, the ozone layer has shown signs of recovery in recent years. However, continued monitoring and adherence to global agreements are essential to ensure the long-term protection and recovery of the ozone layer.

Answer:

Water vapor in the wind.

Explanation:

Running water is a powerful agent of erosion, shaping the Earth's surface through processes such as weathering, transportation, and deposition. However, there are certain materials or substances that running water may not erode significantly.

Some examples include:

Bedrock: Running water can erode and shape softer rocks, but it has limited effectiveness in eroding hard bedrock. Bedrock refers to solid rock formations that underlie soil, sediment, or other loose materials. While running water can contribute to the weathering of bedrock over long periods, the erosion of solid bedrock primarily occurs through other geological processes like glaciation or tectonic activity.

Certain Minerals: Some minerals are highly resistant to erosion by running water. For example, minerals such as quartz and diamond are extremely hard and resistant to mechanical weathering caused by water flow. These minerals are more likely to be transported by water rather than eroded.

Clay and Silt: Clay and silt particles are very fine and have cohesive properties. While running water can transport and suspend clay and silt particles, they are less likely to be eroded or broken down by the force of the water. However, prolonged water flow can still cause gradual erosion and sedimentation of clay and silt.

It's important to note that while running water may have limitations in eroding certain materials, it can still contribute to erosion in various ways, such as channel formation, the cutting of valleys, and the transportation and deposition of sediment.
