12) What is the difference between cleavage and fracture?
13) A geologist did not bring a bottle of dilute acid with
them to the field. Which mineral property can they use to differentiate
felspar from calcite without acid? Describe the test for the mineral
property and what the results will be for each mineral.
Answers
12. Cleavage and fracture are both terms used to describe how minerals break, but they differ in the way the breakage occurs.
13. The geologist can use the property of hardness to differentiate feldspar from calcite without acid
12. Cleavage: Cleavage refers to the tendency of a mineral to break along planes of weakness, producing flat, smooth surfaces. These surfaces are often parallel to specific crystallographic planes or directions of the mineral's atomic arrangement. Cleavage can be described by the number and orientation of the resulting flat surfaces. Minerals with good cleavage break easily along these planes, and the resulting fragments typically have regular shapes and smooth edges.
Fracture: Fracture describes the way a mineral breaks when it does not exhibit cleavage. Unlike cleavage, fracture does not occur along planes of weakness but rather involves irregular or curved surfaces. The resulting fragments from fracturing can have jagged, rough edges, and the shapes may be irregular.
Cleavage and fracture are terms used to describe how minerals break. Cleavage refers to the tendency of a mineral to break along planes of weakness, producing flat, smooth surfaces, while fracture describes irregular or curved breakage surfaces without following specific planes of weakness.
13. Hardness: Hardness is a mineral property that refers to its resistance to scratching. It is measured on the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest). Feldspar has a hardness of 6 on the Mohs scale, while calcite has a hardness of 3.
Test for hardness:
The geologist can perform a scratch test to determine the hardness of the mineral. They can use a mineral of known hardness, such as a fingernail (hardness of around 2.5), a copper penny (hardness of around 3), or a steel nail (hardness of around 6.5-7). By trying to scratch the mineral in question with these known hardness materials, the geologist can assess whether the mineral is harder or softer.
Results:
If the mineral can be scratched by a fingernail or a copper penny but not by a steel nail, it is likely to be calcite, as calcite has a hardness between 2.5 and 3.
If the mineral cannot be scratched by a fingernail or a copper penny but can be scratched by a steel nail, it is likely to be feldspar, as feldspar has a hardness of 6 and is harder than calcite.
In the absence of dilute acid, the geologist can differentiate feldspar from calcite using the property of hardness. By performing a scratch test with materials of known hardness, they can assess whether the mineral is harder or softer, allowing them to distinguish between feldspar (hardness of 6) and calcite (hardness of 3).

how does a glacier, at its base and sides, modify a bedrock valley? multiple select question. ice is hard, and it cuts gouges into the rock surface. the valley becomes much more jagged. sediment is left behind on the sides and bottom of the valley. rocks carried by glaciers grind and scrape the rock surface. the rock beneath may be smoothed, polished, and scratched.
Answers
A glacier has a significant impact on the bedrock valley through its movement and the physical properties of ice. At the base of the glacier, ice is hard and has the ability to cut and gouge into the rock surface, resulting in a much more jagged valley.
The sides of the valley also experience the effects of the glacier, with sediment being left behind as the ice melts and retreats. The rocks carried by the glacier grind and scrape the rock surface, leading to the rock beneath being smoothed, polished, and scratched.
Over time, this can result in a U-shaped valley, where the glacier has widened and deepened the original V-shaped valley. Additionally, the ice's weight and movement can cause fractures and cracks in the bedrock, which can contribute to further erosion and modification of the valley.
Overall, a glacier's presence and movement have a significant impact on the bedrock valley, resulting in a range of modifications that can be observed and studied.

which production is most likley to be loacted in less developed countires
Answers
Production that requires a significant amount of labor is most likely to be located in less developed countries.
This includes labor-intensive manufacturing such as textile and clothing production, footwear, and low-end electronics. These industries typically require a large workforce and have low-profit margins. Therefore, companies are attracted to countries where labor is cheap and there are few regulations. Many multinational corporations have moved their production facilities to countries such as Bangladesh, Vietnam, and Cambodia, where labor is abundant and cheap. The workers in these countries are often paid low wages and work in poor conditions, with long hours and little job security. However, despite these negative aspects, these industries provide employment opportunities and are often an important source of income for many people in less developed countries. In addition, the extraction of natural resources such as minerals, timber, and oil is also more likely to occur in less developed countries due to the abundance of these resources. Companies are attracted to these countries because of the low cost of labor and the often lenient environmental regulations. Overall, production that requires a significant amount of labor or the extraction of natural resources is most likely to be located in less developed countries. However, it is important for companies to ensure that they are not exploiting the workforce or damaging the environment in these countries.

Can the age of Earth be reliably estimated from sediment thicknesses?a.Yes: sedimentation rates remain constant at any one locality throughout Earth’s history.b.Yes: sedimentary rocks are rarely metamorphosed or melted.c.No: sedimentary rocks make up only a small fraction of the rocks on Earth’s surface.d.No: much of Earth’s history is represented by unconformities between strata rather than thestrata themselves.
Answers
The age of Earth can be reliably estimated from sediment thicknesses, but there are several factors to consider.
The correct option is A.
Sedimentation rates remain constant at any one locality throughout Earth’s history, so the thickness of sedimentary rocks can be used to estimate the age of the Earth at that location.
Additionally, sedimentary rocks are rarely metamorphosed or melted, meaning that they are more likely to retain their original characteristics and thus be more reliable indicators of Earth’s age. On the other hand, sedimentary rocks make up only a small fraction of the rocks on Earth’s surface, and much of Earth’s history is represented by unconformities between strata rather than the strata themselves.
Therefore, sediment thicknesses can provide an estimate of Earth’s age, but other methods should also be used to corroborate the results.
The correct option is A.

Answer:
The correct answer is D. To examine and compare population densities using one view of the entire world I would use the Robinson Projection.
Explanation:
Robinson Projection is a non-equivalent projection based on coordinates and not on mathematical formulation, having been designed to minimize angular and area distortions. In this projection the latitude parallels are straight, but the longitude meridians are not. The advantage of the Robinson projection is that it looks very natural. It shows relatively large deviations in angle and area only in the area of the poles, which increase with the distance from the central meridian. However, it is not distortion-free in any area.

Answers
2.They were motivated by their desire for freedom.
4.They were warned ahead of time that the British were coming.
Explanation:
The colonists were not well-trained, and they did not have plenty of supplies and equipment. They were mostly farmers and tradespeople, and their militias were not professional armies.
The colonists were highly motivated by their desire for freedom and their opposition to British rule.
General Washington did not command the colonial forces at the Battles of Lexington and Concord. He did not become commander-in-chief of the Continental Army until after these battles.
The colonists were indeed warned ahead of time that the British were coming. Paul Revere and other riders spread the news that the British were marching from Boston to Concord to seize colonial arms and ammunition. This gave the colonists time to prepare and to muster their militia forces.

Answers
Geologists define geologic formations as a rock that has been completely lithified .
Describe the process of lithification .
Lithification is a difficult process that turns loose silt grains that have just been deposited into rock. Lithification might take place either right away or later after a sediment is deposited. One of the key procedures, particularly for sandstones and conglomerates, is cementation. In addition, interactions between different minerals and between minerals and the fluids confined in the pores within a sediment occur; these processes, together referred to as autheigenes, may create new minerals or supplement those already present in the sediment.
Minerals in solution entering the sediment from another region may be deposited or may interact with minerals already there. Minerals may also be dissolved and redistributed form nodules and other concretions. By pressing the grains into different arrangements, the sediment may be compressed.
