1. Sea floor spreading is the cause of the gradually expanding distance between South America and Africa.
The idea of a moving seafloor and how it carries the continents with it was first proposed in 1960 by Harold Hammond Hess of Princeton University and Robert Dietz of the U.S. Naval Electronics Laboratory. This phenomenon is known as plate tectonics. At the mid ocean ridges, where it occurs, plates separate, causing seafloor spreading, which leads to the production of new sea floor.

3. When viewing the Grand Canyon in the United States, one may see layered sedimentary rock that has been exposed by erosion.
Lava flow and horizontally stacked rocks make up the Grand Canyon. Grand Canyon contains over 40 significant sedimentary layers that range in age from 200 million to 2 billion years.
4. Australia is made out of a thick, comparatively old continental crust.
The continental crust of Australia measures an average of 38 km in thickness, excluding the thinner margins, with a range of 24 to 59 km.
5. Subduction is what created the Marianas Trench, an exceptionally deep ocean trench.
The oceanic trench is a depression in the ocean floor that is both lengthy and small in breadth.
The crescent-shaped Marianas trench is renowned for having some of the planet's deepest spots. When two plates collide and one thrusts beneath the other, subduction occurs.
6. Dense, relatively young rock makes up the seafloor crust in the Atlantic Ocean between North America and Europe.

The principal difference between a marine west coast climate and a Mediterranean climate is
In comparison to a Mediterranean climate, the West Coast's marine climate has milder annual temperatures. Due to the significant impact of midlatitude cyclones, Marine West Coast climates experience higher annual precipitation totals than Mediterranean climates, which are also more evenly distributed throughout the year.
The Mediterranean climate is what?A temperate climate sub-type known as a Mediterranean climate, also known as a dry summer temperate climate Cs, is characterized by dry summers and mild, wet winters.
The Mediterranean Basin, where this climate type is most prevalent, gave rise to the name of the climate. Mediterranean climate zones are typically found between roughly 30 and 45 degrees north and south of the equator, along the western coasts of continents.
The subtropical ridge, which grows toward the hemisphere's pole during the summer and migrates toward the equator during the winter as a result of the seasonal poleward-equatorward temperature variations, is the primary contributor to the Mediterranean, or dry summer climate.

What has globalization done to influence income and wealth inequality in the United States? Include the influence of the Industrial Revolution and geography in your answer. Why did Europe develop first?
Globalization's rise in recent decades has increased income inequality in the U.S. while benefitting the executives, according to a study done by the National Bureau of Economic Research which directly connects globalized commerce with a prominent wage gap in the country.
The global trade dynamics encountered a huge shift during this time frame – particularly in the 1990s and 2000s, which saw the signing of the North American Free Trade Agreement (NAFTA) and China joining the World Trade Organization. Both events have been acknowledged by globalization critics, especially by President Donald Trump, as key turning points for the U.S. economy.
Although, Europe represents only about 8 percent of the Earth's landmass, from 1492 to 1914, Europeans colonized more than 80 percent of the entire world, which started with the gunpowder technology. Though it was invented in China and used in Japan and Southeast Asia, the Europeans excelled at using it, which catered to their successful conquests.
Gunpowder was very important for conquering territory as it allows a small number of people to impose a lot of influence. The technology grew to include more than just guns: armed ships, fortifications that can resist artillery, and many more, and the Europeans became the finest at using these things.

What is mineral?
A mineral or mineral species is, generally speaking, a solid chemical compound with a very well-defined chemical composition and a particular crystal structure that occurs naturally in pure form in geology and mineralogy. Compounds found only in living creatures are typically not considered minerals according to geological definitions. However, some minerals, like calcite, are frequently biogenic or, in the context of chemistry, are organic molecules (such as mellite). Additionally, living things frequently produce inorganic minerals (like hydroxylapatite), which are also found in rocks. Rock, which is defined as any bulk solid geologic substance that is sufficiently massive and sufficiently homogeneous, is not a mineral. A rock can be made of a single type of mineral or it can be an amalgam of two or more different mineral types that have been spatially separated into different phases.

Will marine food sources keep up with human population growth?
The marine food sources will not be able to keep up with human growth population.
There isn't much space for hope. There doesn't seem to be enough water available for agriculture to produce enough food to feed the world's 9200 million inhabitants.
Already under water stress, the current population is made worse by the interaction between population expansion and climate change. Additionally, since the middle of the 1980s, worldwide fisheries landings have been dropping, which has added to the current crisis in food production.
The food-producing industry least dependent on the availability of freshwater, marine aquaculture (hereinafter mariculture), will be used to help feed humanity in the twenty-first century.
Although there is still room for growth in northern temperate regions, despite significant intensification (such as a 10-fold increase in the yield of Chinese freshwater aquaculture in 20 years), freshwater aquaculture is becoming increasingly spatially constrained in the tropics and subtropics due to rapid human population growth and the concomitant high requirements for direct use of water and land.

If the earth’s tilt on its axis were to increase by 20 degrees, at what latitude would you find the tropic of capricorn?.
The tropics are at 43 degrees 27' and the polar circles are at 45 degrees 27'. It would be an interesting evolution to adapt to the rapid and dramatic changes in the seasons.
More tilt means more severe seasons—warmer summers and colder winters; less tilt means milder summers and winters. The axial tilt of the Earth (also known as the obliquity of the ecliptic) is approximately 23.5 degrees. Because of this axial tilt, the sun shines at different angles on different latitudes throughout the year. This is what causes the seasons. Uranus has the solar system's largest axial tilt.

A place such as central pennsylvania, home of penn state’s university park campus, is fairly typical of the world in terms of rainfall. What happens to the rain that falls on central pennsylvania each year?.
Rain that falls on central Pennsylvania each year most of it is evaporated.
Life depends on water, and life is highly adept at utilising it. Trees consume practically all of the rain that falls when their leaves are out, and tree roots reach deep into the soil and draw up some of the water from cold-season rain and snowmelt.
Even though plants still receive the majority of water, a sizable portion of it does sink into the ground and run to streams (perhaps 1/3 of the total). Although much of the land is not paved and little water flows across natural surfaces to streams, the quantity of water that does flow across the surface is growing as we pave the terrain.
Direct rainfall into streams, lakes, and rivers is minimal because they make up such a small portion of the landscape. Although "frackers" need water mixed with additional chemicals for the recovery of natural gas, they do not use nearly as much water as trees do. Additionally, even if the precise chemical make-up of the frack waters is a trade secret, we are confident that it does not consist of soda!

In an effort to understand the diffusion of language, the Sedentary Farmer Theory__________.
In an effort to understand the diffusion of language, the Sedentary Farmer Theory was given by British archaeologist Colin Renfrew in 1987.
What was the Sedentary Farmer Theory?The Proto-Indo-European dispersion started in Neolithic Anatolia, according to the Anatolian hypothesis, also known as the Anatolian theory or the sedentary farmer idea, which British archaeologist Colin Renfrew initially put out in 1987.
It is the principal rival of the Kurgan hypothesis, sometimes known as the steppe idea, which is more well-liked among academics. According to the theory, Indo-European languages started to diffuse peacefully throughout Europe from Asia Minor at approximately 7000 BC as farming technology advanced during the Neolithic period (wave of advance).
As a result, Indo-European languages would have been spoken by the majority of Neolithic Europeans, and later migrations would have replaced these languages with other Indo-European languages.

What type of rock is formed through the solid-state alteration of a previously existing rock, by heating, pressure, and/or chemically active fluids?.
Metamorphic rocks are the rocks that are formed through the solid-state alteration of a previously existing rock, by heating, pressure, and/or chemically active fluids.
The word "metamorphosis" literally means "shape transformation." Rocks undergo metamorphism, which is the structural, chemical, and mineralogical adaptation of solid rocks to the physical and chemical conditions imposed at depth below the surface.
Usually, metamorphism takes place below the surficial zones, where the processes of cementation, compaction, and sedimentation occur. When a rock is exposed to conditions that are different from those in which it developed, metamorphism may occur.
A rock that was once one type of rock but changed to another under the action of heat, pressure, or fluids without going through a liquid phase is referred to as metamorphic (without completely melting).
Every time rocks experience changes in heat, pressure, or exposure to chemically reactive fluids, they undergo metamorphic transformations. These fluids include a variety of gases and liquids that exist under pressure inside the Earth, mostly water and steam.
