When magma solidifies underground, the resulting landform is classified as _______.

galina1969 [7]

Answer:

1. When magma solidifies underground, the resulting landform is classified as <u><em>Intrusive rocks. </em></u>

2. Lava cooling on the surface of the earth forms <u><em>Extrusive igneous rocks </em></u> features.

3. A very large mineral is more likely to be found in <u><em>Igneous</em></u> rock.

4. <u><em>Lava</em></u> is magma that forms in long, horizontal shafts in the earth’s crust.

5. Lava with high basalt content forms <u><em>high ferromagnetism</em></u> through multiple eruptions.

Explanation:

1. Intrusive rock is formed when magma penetrates existing rock, crystallizes and solidifies underground to form intrusions. Intrusive rock forms within Earth's crust from the crystallization of magma.

2. Extrusive igneous rocks form when magma reaches the Earth's surface of a volcano and cools quickly. Most extrusive rocks have small crystals.

3. Igneous rock or magmatic<em> rock</em>, is one of the 3 main rock types. The other 2 are called <em>sedimentary</em> and<em> metamorphic</em>. Igneous rock is formed through the cooling and solidification of magma or lava.

4. Lava is molten rock generated by geothermal energy and expelled through fractures in planetary crust or in an eruption, usually at temperatures from 1.292 to 2.192 °F.

5. Mafic or basaltic lavas are best known by their <em>high ferromagnesian content. </em>

Eruptions associated with basaltic lava usually are <em>not explosive</em> due to the low silica and gas content.

Because of the low viscosity, basaltic lava flows spread out, forming extensive layers. They may build up to form a large shield volcano.

List and describe at least four reasons why some countries are rich and some are poor. Long Explanation Required!

ikadub [295]

Answer:

Explanation:

In common language, the terms "rich" and "poor" are often used in a relative sense: A "poor" person has less income, wealth, goods, or services than a "rich" person. When considering nations, economists often use gross domestic product (GDP) per capita as an indicator of average economic well-being within a country. GDP is the total market value, expressed in dollars, of all final goods and services produced in an economy in a given year. In a sense, a country's GDP is like its yearly income. So, dividing a particular country's GDP by its population is an estimate of how much income, on average, the economy produces per person (per capita) per year. In other words, GDP per capita is a measure of a nation's standard of living. For example, in 2016, GDP per capita was $57,467 in the United States, $42,158 in Canada, $27,539 in South Korea, $8,123 in China, $1,513 in Ghana, and $455 in Liberia (Figure 1).

Because GDP per capita is simply GDP divided by the population, it is a measure of income as if it were divided equally among the population. In reality, there can be large differences in the incomes of people within a country. So, even in a country with relatively low GDP, some people will be better off than others. And, there are poor people in very wealthy countries. In 2013 (the most recent year comprehensive data on global poverty are available), 767 million people, or 10.7 percent of the world population, were estimated to be living below the international poverty line of $1.90 per person per day.3 Whether for people or nations, the key to escaping poverty lies in rising levels of income. For nations specifically, which measure wealth in terms of GDP, escaping poverty requires increasing the amount of output (per person) that their economy produces. In short, economic growth enables countries to escape poverty.
