Answer:
4.6 to 4 billion years ago
Explanation:
Hadean time (4.6 to 4 billion years ago)* is not a geological period as such. No rocks on the Earth are this old, except for meteorites. During Hadean time, the Solar System was forming, probably within a large cloud of gas and dust around the sun, called an accretion disc.
Answer:
They basically solved reasoning to laws and just things that needed a change
Explanation:
Different parts of Earth's surface receive different amounts of sunlight (Figure below). The Sun's rays strike Earth's surface most directly at the Equator. This focuses the rays on a small area. Near the poles, the Sun's rays strike the surface at a slant.
Many factors, both natural and human, can cause changes in Earth's energy balance, including:
Variations in the sun's energy reaching Earth.
Changes in the reflectivity of Earth's atmosphere and surface.
Changes in the greenhouse effect, which affects the amount of heat retained by Earth's atmosphere.
The correct answer is C) The dismantling of the Berlin Wall and the end of restrictions on emigrating from communist countries.
A significant long-term cause of the collapse of the Soviet Union during the late twentieth century was the dismantling of the Berlin Wall and the end of restrictions on emigrating from communist countries.
After many years under the Communist regime, the Soviet Union split in December 1991. During those Communist years, the USSR never allowed private property in the Soviet United. The state was the owner of the means of production.
So when Gorbachev decided to implement glasnost and perestroika reformations, he had to carefully proceed because these involved some kind of risk. Glasnost allowed people more rights such as the freedom of speech and freedom of the press. Perestroika allowed new and private investments to revitalize the difficult economic conditions of Russia.
The Soviet Union ceased to exist on December 26, 1991. Gorbachev had resigned one day before and the new leader of Russia was Boris Yeltsin.
