We can see here that the type of plate motion that is most likely causing the patterns of volcanic activity and earthquakes in an area depends on the specific tectonic setting and the geological features of the area.

For example, if the area is located along a divergent plate boundary, where two tectonic plates are moving apart from each other, then the volcanic activity and earthquakes are likely caused by the movement of magma and the fracturing of the crust as the plates separate.

Volcanic activity refers to the processes, phenomena, and events that are associated with the eruption of molten rock, ash, and gas from the Earth's crust through a vent or opening in the surface.

Volcanic activity can take many forms, ranging from quiet, slow-moving lava flows to explosive eruptions that can eject ash, rock fragments, and volcanic gases into the atmosphere.

Censuses are preferable over capture-mark-recapture in small populations, when habitat quality changes significantly, or for specific life stages, ensuring more accurate population estimates.

Ecologists might prefer an actual count of every individual in a population (census) rather than using the capture-mark-recapture method in the following situations: Small population sizes: When the population is small, ecologists might choose to use a census rather than the capture-mark-recapture method because of the small sample size. If the sample size is too small, then the precision of the estimates becomes weak.

In such instances, the probability of animals being recaptured may be too small, causing imprecise estimates. Changes in habitat quality: A capture-mark-recapture method is an excellent tool for comparing population estimates between different years, but it cannot capture any changes in the habitat. The population estimate becomes questionable if the habitat has undergone significant changes between the capture periods.

For example, a census would be the most effective method for detecting a change in the population of a migratory bird species caused by habitat loss or disturbance, while the capture-mark-recapture method would be unsuitable. Example: Say that a particular bird species population is being monitored over time with the capture-mark-recapture method.

The population of the birds increased due to an increase in the food supply, but during the same period, a group of trees that provided shelter for these birds were destroyed by a forest fire. The bird population size estimate obtained through the capture-mark-recapture method would not account for the destruction of the trees and therefore would be invalid.

Specific life stages: When dealing with particular life stages or sizes of the population, a census may be necessary. For example, during the breeding season, migratory birds form colonies, which makes it hard to capture them using the capture-mark-recapture method. In such situations, it may be more effective to do a census.

Underground coal mining is more dangerous and labor extensive compared to strip mining, so it is also more expensive.

The process of removing coal from the earth is known as mining. Because of its high energy content, coal has been utilized extensively to produce electricity since the 1880s. Coal is used as a fuel in the steel and cement industries to extract iron from iron ore and to make cement.

Environmental concerns have become more significant since 1970, including the health of workers, the degradation of the environment caused by strip mining and mountaintop removal, air pollution, and the impact of coal burning on global warming. By removing the ground above each coal seam, strip mining exposes the coal. The earth that has to be removed is known as "overburden" and is taken out in broad strips.

(b) Size of the first image:

The size of the first image formed by the objective lens can be calculated using the formula:

h = Do * θ

Where h is the size of the image, Do is the diameter of the objective lens, and θ is the angular size of the lunar crater.

The angular size of the lunar crater can be calculated as:

Therefore, the size of the first image formed by the objective lens is 0.0867 mm.

(c) Length of the barrel of the telescope:

The length of the barrel of the telescope is the sum of the focal lengths of the objective and eyepiece lenses. Substituting the given values, we get:

Length of the barrel = 18.8 m + 0.12 m = 18.92 m

Therefore, the length of the barrel of the telescope is 18.92 m.

(d) Angle subtended at the unaided eye by the lunar crater:

Mixed cropping involves growing different crops together,
while mixed farming involves combining crop production with animal husbandry.

LONG ANSWER:

Mixed cropping and mixed farming are two different agricultural practices with distinct differences:

1. Mixed cropping: It is a practice of growing two or more crops simultaneously in the same field. The crops are selected in a way that they complement each other in term of nutrient requirements, growth habits, and time of maturity. This practice is also known as intercropping. The main aim of mixed cropping is to maximize the use of available resources and increase productivity. Examples of mixed crops are maize an beans, wheat and peas, and sorghum and cowpeas.

2. Mixed farming: It is a practice of combining crop production with animal husbandry ir the same farm. The crops grown in mixed farming are used to feed the livestock, and the animal waste is used as manure to improve soil fertility. This practice aims at maximizing the use of available resources and diversifying income sources. Mixed farming includes activities like growing crops, raising animals, and processing and marketing of farm products. Examples of mixed farming are dairy farming, poultry farming, and sheep rearing.

To determine the most likely identity of the unknown mineral based on its scratching behavior, we need to consider the relative hardness of different minerals. Hardness is a measure of a mineral's resistance to scratching or being scratched by other substances.

Based on the information provided, we can infer that the unknown mineral is harder than copper (which is relatively soft) since it can scratch a copper coin. However, it is not harder than the pocket knife blade since it cannot scratch it.

The most commonly used scale to assess mineral hardness is the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest). Given the scenario, the most likely identity for the unknown mineral would be a mineral with a hardness between that of copper (2.5-3 on the Mohs scale) and the pocket knife blade (around 5-6 on the Mohs scale).

Considering this, a possible identity for the unknown mineral could be a mineral with a hardness around 4 on the Mohs scale, such as fluorite or orthoclase feldspar. However, without further information or conducting additional tests, it is challenging to determine the exact identity of the mineral with certainty.

No, the above statement is false. In the Northern Hemisphere, the water surface of the open ocean moves approximately 45° to the right of the wind.

This phenomenon is known as the Ekman transport. Due to the Coriolis effect, which deflects moving objects to the right in the Northern Hemisphere, the net movement of water particles is at an angle of about 45° to the right of the wind direction. This means that the wind pushes the surface water at an angle, and the resulting movement of water is slightly to the right of the wind direction. It is important to note that this 45° angle is an average and can vary depending on factors such as wind speed and ocean depth.
