<u>Answer:</u>
It would <em>diminish the estimation of the dollar and Americans</em> wouldn't have the option to trade their dollars for gold any longer, <em>such huge numbers of americans took out their cash and traded it for gold before this would occur.</em>
<u>Explanation:</u>
<em>Surrendering the highest quality level helped the economy develop. </em>This trade of gold for paper cash enabled the United States to build the measure of gold stores at the <em>United States Bullion Depository at Fort Knox. </em>
It would diminish the estimation of the dollar and Americans wouldn't have the option to trade their dollars for gold any longer, such <em>a large number of americans took out their cash and traded it for gold before this would occur.</em>
The statement that is a key difference between market economy and mixed market economy is this: Market economies have no government influence while mixed market economies are loosely regulated by the government. Hope this is the answer that you are looking for.
Answer:
Volcanism: eruption of molten rock onto surface
tectonics: disruption of planet's surface by internal stresses
erosion: surface changes by water,wind or ice
Impact: impacts by asteroides or meteorites
Explanation:
Terrestrial planets have hard surfaces that can be reshaped by 4 major geological processes, that are:
- volcanism
- erosion
- tectonics
- impact cratering
Each of these processes is caused by different things. For e.g :
Volcanism happens when hot lava reaches the surface and give rise to volcanic planes e.g runny lava makes flat lava plains, while thickest lava makes steep stratovolcanoes
Erosion: is a geological process that removes rock, soil or dissolved materials and transport them by wind or water from one location of earth's crust to another. Example of erosion caused by ice, Glaciers carved by Yosemite Valley.
Tectonics: internal stresses in the earth caused by convection of mantle give rise to tectonic forces. Example compression forces give rise to mountain ranges. And valleys are formed at the point where a cryst is pulled apart
Impact cratering: This is caused when a meteorites or asteroides hits a planet's surface. Impact catering happened immediately after the solar system was formed.
The correct answer is - B) convection currents in the mantle.
There's multiple tectonic plates on the surface on the planet, around 17 from what is known so far, but as the scientific methods are developing there might be few more discovered in the years to come.
These plates are all moving, only few cm per year, but on the long term it influences and changes everything on the surface on the Earth.
The movement of the plates is the result of the convection currents in the mantle layer beneath. These convection currents are essentially the combination of the high temperatures, high pressures, and viscous metals, and they managed to break up the crust on the surface, and with its push force, they are slowly moving the plates.
With the movement of the plates and their collisions and moving away, lots of earthquakes and volcanoes are appearing all over the plate boundaries.
