Why is halite found on the surface of Earth

Answers

Answer:Halite and some of the other salt minerals are highly soluble, so dissolve in the presence of undersaturated water. This occurs primarily in the phreatic zone due to the circulation of meteoric groundwater and thus is characteristic of nonmarine environments.

Halite is usually found in and around salt springs, salt lakes, and in the ocean. It can also be found in salt domes, with are actually quite common in the Michigan Basin, and provide important traps for oil deposits.

rocks from which source would most likely contain the highest percentage of iron-bearing minerals?

Answers

Ocean floor would most likely contain the highest percentage of iron bearing minerals.

Ocean-dwelling organisms like cyanobacteria produce oxygen, which results in the formation of thin bands of iron on the ocean floor. The oxygen produced results in these iron ores.

Over the span of a billion years, enormous quantities of iron were accumulated at the ocean floor. These occurrences took place around 3.5 and 2.5 a billion years ago. The enormous reserves that were created at that time include the iron ore that is being mined in South Africa, Australia, and the United States. Once the iron was removed from the water, oxygen could begin to accumulate in the air and sophisticated life forms could begin to breathe deeply. The duration of this process is one billion years .In Earth history, the Archean era came to an end once it was completed.

A mineral within a metamorphic rock that can be used to provide a narrow constraint on the temperature and pressure of rock formation is termed a(n) ________ mineral. Group of answer choices

Answers

A mineral within a metamorphic rock that can be used to provide a narrow constraint on the temperature and pressure of rock formation is termed  index mineral.

Index minerals are used to help geologists understand the geologic history of a rock, as they are resistant to alteration by heat and pressure. Index minerals form in rocks that have been subjected to specific temperatures and pressures. They are used to indicate the range of temperatures and pressures under which a rock was formed.

For example, the index mineral biotite forms in rocks that have experienced temperatures between 400 and 500° Celsius and pressures between 2-4 kbar.

In addition to providing an indication of the temperature and pressure of a rock’s formation, index minerals can also help geologists determine the rock’s chemical composition. Different minerals form under different chemical conditions and can be used to identify the composition of a rock.

Index minerals are used in combination with other methods to provide a more detailed and accurate picture of the geologic history of a rock. This allows geologists to better understand the processes that have shaped the rocks in a given area.

How do the preparation and mitigation measures for earthquake and volcanoes differ from other natural hazards discussed

Answers

Preparation and mitigation measures for earthquakes and volcanoes differ from other natural hazards in a number of ways:

Earthquake:
Building codes and construction methods are designed to make buildings more resistant to shaking and collapse during an earthquake.

Retrofitting existing buildings to improve their seismic resistance.

The installation of early warning systems in high-risk areas to give people a few seconds to take cover before an earthquake strikes.

Developing emergency response plans for communities and organizations.

Conducting regular drills to familiarize people with what to do during an earthquake.

Identifying and regularly updating hazard maps of areas at risk from earthquakes

Volcanoes:
Monitoring of volcanic activity, including measuring changes in the level of a volcano's magma chamber, and tracking gas emissions.

Evacuation plans, and emergency shelters prepared for high-risk areas.

Providing forecasts of volcanic activity and ash fall, to inform decision-making.

Mapping and zoning of high-risk areas around volcanoes.

Regularly conducting drills for evacuation, for the public and for schools

Mapping lahars and pyroclastic flow hazard zones

Compared to other natural hazards, such as hurricanes or floods, earthquakes and volcanoes tend to affect smaller areas, but they can be highly destructive in those areas. They also tend to be less predictable and can strike with less warning. Preparing for these hazards requires a different set of techniques and plans.

What type of rocks were once another type but have been changed as a result of intense heat and pressure?

Answers

Metamorphic Rocks were once another type but have been changed as a result of intense heat and pressure.

On Earth, rocks can be igneous, sedimentary, or metamorphic. When rocks are heated to the point of melting, which results in magma, igneous rocks are created. Sedimentary rocks are produced by the cementing, compaction, or crystallisation of new mineral grains that are bigger than the original crystals, or by the compression of sediments. Rocks that have undergone metamorphism have undergone a full transformation due to heat and pressure.

The parent rock may be igneous, sedimentary, or even a different metamorphic rock. Metamorphic, which meaning "To Change Form," is a Greek term. Stresses that raise pressure and heat can transform solid rock into a new type of rock. There are three primary factors that trigger metamorphism. The three agents are those which result in a change in temperature, stress, and chemical changes.

Is river an example of groundwater?

Answers

Groundwater is found in rivers. However, because precipitation penetrates into (and travels) into the earth.

you may not realize that a considerable percentage of the water flowing in rivers originates from groundwater seeping back "up" into the river from below.

Groundwater sources include springs and wells under the ground surface. When rain falls on the ground, some water runs along the land to streams or lakes, some evaporates into the atmosphere, some is taken up by plants, and some seeps into the earth, as shown by the hydrologic cycle.

When surface water from precipitation, streams, and rivers reaches the water table, it naturally replenishes groundwater.

Hi
Can someone give me a good explanation of what happens on a constructive plate boundary and also give me an example of constructive plate boundaries

Answers

Answer:

A constructive plate boundary is when two plates move away from each other, causing molten material from the Earth’s mantle to rise up and form new crust between them. This type of boundary is responsible for the formation of new land due to the movements of the plates. An example of a constructive plate boundary is the Mid-Atlantic Ridge which is located between the North American and Eurasian plates. As these two plates move away from each other, magma from the mantle rises up and creates new oceanic crust, resulting in the formation of new land masses in the form of islands.

How do logarithms relate to the Richter scale?

Answers

Earthquakes are measured using the Richter Scale, which is a base 10 logarithmic scale. The magnitude of an earthquake is measured by this scale, which is the amount of energy generated by it.

The magnitude increases by a factor of ten for every single rise on this scale.

In comparison to a linear scale, the logarithmic scale provides a simpler and more comprehensible manner to describe the large range of ground motion amplitude (sometimes several orders of magnitude) and energy release for distinct quakes within a tolerable range of values.

To calculate the Richter scale measure, express the amplitude in millimeters as 10 multiplied by an exponent (10x).

What is the connection between decolonization and neocolonialism?​

Answers

Decolonization refers to the process of a colony gaining independence from its colonizer and establishing itself as a sovereign nation. Neocolonialism, on the other hand, refers to the ongoing economic, political, and cultural influence and control that former colonizers maintain over their former colonies.


The connection between the two is that, while decolonization may have led to the end of formal political control, the legacy of colonization may persist through neocolonialism. This can be seen in the ways in which the economies, political systems, and cultures of formerly colonized nations are shaped by the interests and policies of the former colonizers.

It can also manifest in the form of dependency on the former colonizers in economic, political, and cultural terms which is hard to break even after gaining formal independence. The neocolonialism can be achieved by different means such as trade agreements, loan conditions, and cultural influence.

How would you describe the distribution of water of water on Earth?

Answers

The distribution of water throughout the Earth's surface is rather varied. Only 3% of the water on the surface is fresh water; the remaining 97% is oceanic.

Less than 1% of freshwater is found in lakes, rivers, and marshes, whereas 69% of it is found in glaciers and 30% is found underground. Humans can only use 1% of the water on Earth's surface, and the majority of that water—99%—is found oceanic.

To see how unequal the distribution of water on Earth actually is, one only has to analyze rainfall maps. They are classified as semi-arid or arid because the white regions on the map below had annual rainfall totals below 400 mm for the previous year. Also keep in mind that estimates call for major aridification in many dry regions and more frequent, more intense rainfall events in wet places.

Mid-ocean ridges (MORs), which are the sites of new oceanic crust formation, are linear mountain chains that run along divergent plate boundaries. Why does an MOR sit up higher than the surrounding oceanic crust

Answers

Mid-ocean ridges (MORs), which are the sites of new oceanic crust formation, are linear mountain chains that run along divergent plate boundaries. MOR sit up higher than the surrounding oceanic crust because of  the hot magma exists the MOR, it shoots up higher than the surrounding crust.

On the ocean floor, there are ridges of mountains called mid-ocean ridges. When two or more plates are moving away from one another, they occur where there are diverging borders.

The thin crust and holes left behind by the relocating plates allow the mantle's intense pressure to easily drive the magma upward. The ocean floor is able to shift up as the magma pushes upward. Rapid magma cooling results in rapid formation of new crust. Due to the magma's ability to raise the ocean floor, the new crust is higher than the previous one.

In addition to continuously coming up and forming more and more new crust, the magma also continuously rises above previously produced layers by building a mountain of extremely hard igneous rocks around the source.
