Metamorphic rocks in which the minerals are oriented in a particular direction, or in which dark and light layers alternate, are said to be foliate metamorphic rocks.
To understand this class of rocks, we first need to elaborate on the nature of foliation. The word comes from the Latin folium, which means leaf. Geologists use foliation to refer to parallel surfaces and/or layers that can occur in metamorphic rocks. Sheeting can give outcropping metamorphic rocks a banded or banded appearance and/or the ability to divide into thin layers. Foliated metamorphic rocks contain different mineral crystals oriented parallel to each other and exhibit foliation because they define preferred mineral orientations and/or because rocks have alternating dark and light layers.
A fine-grained sheet-like metamorphic rock, shale is formed by the metamorphism of shale or mudstone (a rock that is primarily clay) under relatively low pressure and temperature. Slate contains a type of leaf-like structure called a cleavage that allows it to split into thin sheets that make excellent roofing shingles (figure a above). Shale fracturing occurs when a pressure solution grows clay flakes perpendicular to the direction of compression while removing portions of the clay flakes that are not perpendicular to the direction of compression.

why dams and furrows have large number on a topographical map
Answer:
These numbers represent two grid systems that can be used to find your exact location. The first is called latitude and longitude. The exact latitude and longitude is given at each corner of that map and at equally spaced intervals between the corners. The second is called UTM's.
Explanation:
which of these places in latin america has a high minority indian (from india) population? argentina trinidad
There is no sizable Indian minority in either Trinidad or Argentina. However, due to their history of indentured labour under British colonial authority, Guyana and Suriname, both of which are in South America, have high Indian populations.
There is not a significant Indian minority in either Trinidad or Argentina. Less than 0.01% of the country's overall population, or about 4,000 people, are thought to be members of Argentina's minuscule Indian community. On the other side, Trinidad is home to a sizable population of Indo-Trinidadians, who are descended from indentured Indian labourers who were transported to the island during the 19th century. Around 35% of Trinidadians are classified as Indo-Trinidadians, but they are Trinidadian natives with Indian ancestry rather than immigrants from India.

What does the arrow with 15 mph inside it indicate on the weather map?A. The humidityB. The wind speedC. The precipitationD. The air pressure
In a weather map, the arrow with "15 mph" inside it denotes the wind speed at a specific area. The length and thickness of the arrow may be used to determine the wind speed. Wind direction is often depicted by an arrow pointing in the direction that the wind is blowing.
In this instance, the arrow with "15 mph" inside it denotes that the wind speed at that place is 15 miles per hour. This knowledge is crucial for forecasting storm severity, understanding how weather systems move, and determining how wind affects various systems and buildings.. The arrow with "15 mph" inside it on a weather map represents the wind speed at a particular location. Wind direction is typically represented by an arrow pointing in the direction that the wind is blowing, and the length and thickness of the arrow can be used to indicate the wind speed.
In this case, the "15 mph" inside the arrow indicates that the wind speed at that location is 15 miles per hour.

How does economic development affect diffusion?
Answer:
Economic development results in higher levels of education, greater employment opportunities, and higher income levels. Communities are strengthened with economic development because increasing numbers of jobs result in higher income levels.
Answer:
Economic development can have a significant impact on the diffusion of innovations, ideas, and technologies within a society or across different societies. Here are some ways in which economic development can affect diffusion:
Availability of resources: Economic development can increase the availability of resources such as capital, technology, and human resources that are needed to develop and adopt new innovations. With more resources, societies can invest in research and development, create better infrastructure for communication and transportation, and promote education and training to support the adoption and diffusion of innovations.
Market demand: Economic development can also create greater demand for new technologies and innovations, especially in emerging markets that are growing rapidly. This can drive companies and entrepreneurs to invest in the development and dissemination of new products and services that are tailored to the needs of these markets.
Cultural factors: Economic development can also impact the cultural factors that influence the diffusion of innovations. For example, societies with high levels of economic development may have more open and diverse cultures that are more receptive to new ideas and technologies. They may also have more established networks of communication and exchange that facilitate the spread of innovations.
Policy and regulation: Economic development can also lead to changes in policy and regulation that can either facilitate or hinder the diffusion of innovations. For example, policies that promote innovation and entrepreneurship, or that provide funding and support for research and development, can help to accelerate the adoption and diffusion of new technologies.
Overall, economic development can create the conditions that support the adoption and diffusion of new innovations, by increasing resources, creating demand, shaping cultural factors, and driving policy and regulation.
Immigration vs emigration in the American Rocky Mountains chart
Answer:
Immigration
• Population growth in the American Rocky Mountains has been driven by immigration.
• Immigration to the region increased significantly during the 1980s and 1990s, with the majority of immigrants coming from Mexico and Central and South America.
• The influx of immigrants has led to an increase in the population of cities like Denver, Colorado Springs, and Albuquerque.
Emigration
• Emigration from the American Rocky Mountains has been relatively low, with most people leaving the region for other parts of the United States.
• The majority of emigrants are young people seeking better job opportunities or a change of scenery.
• Emigration has been offset by immigration, resulting in a net population gain for the region.
