What is river valley civilization?A river valley civilization is an agricultural nation or civilization that is located alongside a river and draws its subsistence from it. A "civilization" is defined as a society having substantial permanent settlements, social stratification, labor specialization, centralized organization, and written or other formal forms of communication. A river provides residents with a dependable source of water for drinking and cultivation.Impacts of the natural environment on the ancient river valley civilization:Rivers were appealing to the ancient civilizations because they supplied a consistent source of drinking water and made the land conducive for crop cultivation. Furthermore, commodities and people could be easily transported, and the inhabitants of these civilizations could fish and hunt the animals that came to drink water.The Indus Valley was fruitful, flooding was regular and predictable, and there was plenty of land in general. This resulted in the creation of peaceful people who were able to establish spectacular cities with enormous structures and sewage systems without having to battle for resources.

As of 2013, 9 of the 10 warmest years on record were during the 21st century. Only one 20th century year, _____, was among the 10 warmest.

Answers

As of 2013, 9 of the 10 warmest years on record were during the 21st century. Only one 20th century year, 1998 was among the 10 warmest.

How did the temperature of the earth's surface vary between 1900 and 2000?

The average surface temperature of the Earth has risen by around 1.0° F over the past century. All eleven of this century's warmest years have happened since 1980, with 1998 being the warmest year ever recorded. Compared to the equatorial regions, higher latitudes have warmed more.

Since the late 1800s, the average surface temperature of the Earth has risen by around 1.8°F (1.0°C).

After 1880, the ten warmest years have all occurred since 1998, and all but one have done so since 2005.

The Earth's surface absorbs sunlight from the sun as it travels through the atmosphere, warming it. The atmosphere then receives this energy again. The atmosphere's greenhouse gases, such as carbon dioxide and methane, operate as a blanket to collect this energy and keep it from escaping into space. Without the greenhouse effect, the average temperature at the Earth's surface would be 0 degrees Fahrenheit, which is about 60 degrees Fahrenheit lower than the present average. As a result, the greenhouse effect is crucial to the continuation of life on Earth. But when greenhouse gas concentrations rise due to human activity, the earth is becoming warmer and this has an influence on ecosystems and our way of life.

What is the primary reason why mountains substantially taller than Mt. Everest are unlikely to arise on Earth

Answers

One of the main reasons for the fact that is very unlikely for mountains to rise taller than the Mount Everest on Earth is because, mountains give way under their own weight because of the high geothermal gradient in the crust.

The geothermal gradient, which is unchanged from the paleo-geothermal gradient, is the rate of increase in temperature per unit depth in the Earth's interior caused by the core heat flow.In much of the world, it is approximately 25 °C every mile of depth (1 °F per 70 feet of depth) outside of tectonic plate borders.At oceanic spreading centers (mid-ocean ridges) or island arcs where magma is near to the surface, the largest gradients—40–80 K km1—are measured. The subduction zones, where cold lithosphere sinks into the mantle, have the lowest gradients. Old stable continental crust has a gradient of 20–30 K km1.

From the above, it is clear why mountains taller than the Mount Everest, are unlikely to arise on Earth.

List five importance of weather​

Answers

is weather important in people's lives?
Question Date: 2014-09-07
Answer 1:
Good question! Weather is important in people's lives in many different ways. Weather, including winds, thunderstorms, hurricanes, and tornadoes, is really just the earth's way of redistributing heat around its surface.

Heat from the sun causes ocean surface waters to evaporate near the equator; the heat is carried in the water vapor and is released during big thunderstorms and hurricanes.

Winds are caused by pressure gradients, which are formed by hot air rising or cold air sinking.

Weather is important to people in many different ways, but several major examples come to mind:

1) Weather controls the distribution of rain water on earth. All living organisms on earth require liquid water to survive, and humans require fresh (not salty) water for drinking and agriculture (growing crops for food). Droughts can have a major impact on humans and have killed millions of people throughout history.

2) "Severe" weather such as hurricanes, tornadoes, and floods have a huge impact on human civilizations. An obvious example of this was Hurricane Katrina, which impacted a huge are of the gulf coast of the U.S., killed nearly two thousand people, and displaced over one million people from their homes.

3) The first two examples show some of the negative impacts of weather, but weather has also played an important role in the distributions of humans on earth and the development of different cultures. The climate (the long-term weather of an area) ultimately determines if an area will be nice for people to inhabit. Throughout history, climate has influenced migrations of humans over the earth. For example, there is a prevailing idea in archaeology that humans migrated into North America from Asia during a time of colder climate and lower sea level.

There are many ways that weather is important in people's lives; these are just a few examples.
