Answer:

There are many shreds of evidence that support the theory of plate tectonics and make it such a firmly believed idea. These pieces of evidence include fossils, glaciers, earthquakes and volcanic activity, the shape of continents, the magnetism of rocks on the seafloor, the mid-ocean ridge system, and others.

Fossils give an idea of the location of the plants and animals that once existed. Earthquakes and volcanic activity also help in determining the cause of the boundaries and rifts formed. The shape of the continents seems to be fit with one other that gives the idea that these were together and moved away from each other.

B. Low pressure indicates stormy weather is how pressure measurements are related to weather prediction.

Weather forecasting involves utilizing technology and scientific expertise to predict the atmospheric conditions that will prevail in a specific location. Low-pressure areas, characterized by thinner air, are typically associated with specific wind patterns.

The movement of winds in these regions often results in the ascent of air, leading to cloud formation and condensation. Storms occurring in low-pressure areas tend to exhibit well-organized structures.

Active weather conditions are primarily caused by low-pressure systems. The relatively lighter air in these areas has a tendency to rise, leading to the creation of an unstable atmosphere.

Low-pressure systems are responsible for inducing active weather patterns, including gusty winds and rainfall, as well as potentially severe weather events.

Thus, option B is the correct answer.

The building of the Dismal Swamp Canal impacted North Carolina because it speed up the travel of goods from Eastern North Carolina to Virginia.

The Dismal Swamp Canal was dug by hired enslaved labor that is opened for navigation in 1805 after completing the work under unfavorable conditions. The Dismal Swamp Canal length is 22 miles which provide trade between Virginia and North Carolina. In 1929, the Government of the United States of America bought the Dismal Swamp Canal and started to improve its structure and capacity. This canal is also called the oldest operating waterway in the country. It is also part of the Atlantic Intracoastal Waterway. So we can say that this Dismal Swamp Canal increases the speed of trade activities between the two regions.

Gasoline leaks into aquifers contaminate groundwater. Investigation involves assessing contamination extent, monitoring water quality, inspecting soil/buildings, and collecting plume flow/impact data.

Relevant data: groundwater flow rates, contaminant concentrations, soil permeability, proximity to structures/water sources.

The cleanup strategy depends on severity/extent, potentially pumping/treating groundwater, soil remediation, and implementing barriers to halt plume spread.

When gasoline from an underground tank leaks into an aquifer, it can have significant impacts on the surrounding environment.

Gasoline, being a mixture of hydrocarbons, is less dense than water and will float on the water table.

The gasoline will spread horizontally and vertically within the aquifer, creating a plume that can contaminate the groundwater.

The movement of the plume will depend on factors such as the permeability of the aquifer, groundwater flow direction, and the presence of any barriers or confining layers.

In the investigation of the leak, several steps can be taken. First, site characterization is necessary to determine the extent of the contamination and identify potential receptors at risk.

This may involve groundwater sampling, soil sampling, and monitoring well installation.

Specific data required for evaluating the plume flow and impacts may include groundwater flow rates, contaminant concentrations, soil properties, and the proximity of water sources or sensitive receptors.

The proposed cleanup strategy will depend on various factors, such as the extent of the contamination, proximity to receptors, and regulatory requirements.

Common remediation methods for gasoline contamination include pump-and-treat systems, soil vapor extraction, bioaugmentation, and natural attenuation.

The selected strategy should aim to minimize the migration of the plume, remove or treat the contaminated groundwater and soil, and mitigate potential risks to human health and the environment.

Answer:

B. the appearance of lichens and mosses in an area where a glacier has recently melted away

Explanation:

Ecological succession, which refers to the series of changes that occurs over time in an ecosystem, can be of two types namely: primary succession and secondary succession.

Primary succession is a succession that involves an area where no form of life has grown previously, hence, the area of land is barren e.g bare rock. Primary succession is first colonized by species called PIONEER SPECIES e.g. lichens, mosses etc.

According to this question, "the appearance of lichens and mosses (pioneer species) in an area where a glacier has recently melted away" is an example of PRIMARY SUCCESSION.

The oceanic crust sink beneath the continental crust at a subduction boundary as it is pulled downward by Earth's magnetic field. The correct option is B.

The outermost layer of the Earth's lithosphere found beneath the oceans and formed at spreading centers on oceanic ridges that occur at divergent plate boundaries.

The thickness of the oceanic crust is approximately 6 km (4 miles). It is made up of several layers, not including the sediment on top.

The oceanic crust is mostly made up of dark-colored rocks called basalt and gabbro. It is thinner and denser than the continental crust, which is composed of light-colored rocks known as andesite and granite.

Because of its low density, continental crust "floats" high atop the viscous mantle, forming dry land.

As the Earth's magnetic field pulls downward, the oceanic crust sinks beneath the continental crust at a subduction boundary.

Thus, the correct option is B.

The population of white molecules will move from left to right , as the concentration of white molecules is lesser on the right side than on the left.

In the scenario you described, where the concentration of white molecules is higher on the left side and lower on the right side, the white molecules would indeed tend to diffuse from left to right. This is because molecules naturally move from regions of higher concentration to regions of lower concentration in an attempt to equalize the concentration throughout the system.

As the white molecules move from left to right, the concentration gradient across the system will gradually decrease until equilibrium is reached. Hence, movement of molecules will be from higher concentration to lower concentration.
