The _______ era featured the longest periods with no life forms on earth.

Answers

The answer is - Archean.
The Precambrian is the eon before the Cambrian, when the so called life explosion occurred. The Precambrian eon is the earliest part of Earth's history, set before the current Phanerozoic eon. This eon accounts for about 88% of the history of the Earth. It is consisted of three eras, Hadean (no life), Archean (no life), and Proterozoic (life occurred). Both of the two earliest eras do not have life, but Archean is three times longer period than the Hadean, so Archean is the answer.

Answer:Precambrian

In three activities, how can I change my daily habits to help the ecosystem?

Answers

Instead of using a car, use a bike to help not pollute the air. Recycle water bottles. And use energy-efficient light-bulbs.

1. Save water as much as possible :

Hot water from the tap often requires running cold water until we can get hot water. In most cases instead of preserving the cold water in the container to use later, we let it run down the drain and get wasted. This happens in kitchen sinks, bathroom sinks and showers. On a daily basis, a lot of liters of water is wasted this way.

2. Opt for reusable plastic bags :

Bags end up in landfills or causing litter in the environment. The danger of plastic bags is that most of them don't decompose. Animals and birds digest this material and die. Another environmental hazard from plastic bags is increased pollution in rivers, streams and oceans. Therefore, a reusable plastic bag reduces the frequency of buying and disposing, protecting the environment.

3. Do not litter :

Packages whether it is food packaging or packages for other products have a “don't litter” or “throw in a rubbish bin” message and recycling sign. Regardless of that, there is rubbish all over. Avoid littering and using save and recommended manner of disposing of garbage is very important.

Most Middle East countries are highly dependent on food from abroad

The statement is true, most of the countries from the Middle East are heavily dependent on foreign food. Most of this region is desert or semi-desert, so agriculture is not an option. Only few parts manage to produce food, but that is nothing in the whole picture. So the lack of fertile soil and water in this part of the world, made it dependent on foreign food.

Bedrock and sediment in a stream is most susceptible to erosion if it is:

Answers

Bedrock and sediment in a stream are most susceptible to erosion if it is located in a turbulent part of the river.

Constant and fast movement of the water causes the sediments to be displaced and erosion occurs.

ANSWER:

Bedrock and sediment is most susceptible to erosion if it is located in the turbulent part of the stream or the river.

EXPLANATION:

The turbulent part of the river is the one where the water velocity is high. This high water velocity carries away bedrock and sediment easily. The edge where the bedrock and sediment is located tends to be very steep. This steepness makes it easy for the high velocity of water to carry away the bedrock and sediment. This bedrock and sediment is also carried to greater distances because of the great speed of water.

Describe the disaster at Chernobyl.

Answers

On April 26, 1986, the world's worst nuclear accident happened at the Chernobyl plant near Pripyat, Ukraine, in the Soviet Union. An explosion and fire in the No. 4 reactor sent radioactivity into the atmosphere. Plant operators made several mistakes, creating a poisonous and unstable environment in the reactor core. A peculiarity of the design of the control rods caused a dramatic power surge as they were inserted into the reactor.

Answer:

the Chernobyl disaster; during a run-down to a lower power, a combination of operator error and xenon poisoning caused the reactor thermal power to fall to near-shutdown levels. The crew's resulting efforts to restore power placed the reactor in a highly unsafe configuration.

Which statement about trade in the coastal countries of Africa is not true?

Trade is a recent development in coastal countries.

The imports of coastal countries exceed their exports.

Liberia exports iron ore.

Several coastal countries export cash crops.

Answers

The answer is a) Trade is a recent development in coastal countries.

This is an incorrect statement as Trade in the coastal countries of Africa goes back more than a millennium.

During the European colonialism, these countries experienced huge trade growth due to the slave trade and exploitation of natural resources.

Most of these countries had major ports which were used as trading posts, stop-overs and major entry points of West Africa.

After the expansion of the Spanish Empire in South America, trade between the two continents flourished and as late as the 19th and 20th century, European powers were still exploiting natural resources in the region.

Today, the region is growing thanks to billions of dollars of investment from China.

Answer is: (A) Trade is a recent development in coastal countries.

Explanation: the statement above is not true about trade in the coastal countries of Africa this is because trade has existed for as long as the development of coastal countries. They acted as major ports and therefore they were vital for trading. On the other hand, all the other statements mentioned about the coastal countries of Africa are accurate.

The hot spring deposits at mammoth hot springs, yellowstone national park, are travertine. what rock probably lies somewhere beneath the hot springs?

Answers

The type of rock lying beneath the hot springs is a molten rock, or mixture of liquefied hot rocks, better known as magma. This is actually the source of the heat for the hot springs in Yellowstone, as well as for the other geothermal features. Much of Yellowstone lies on a gigantic volcanic crater.

Travertine deposits at Mammoth Hot Springs are formed from the precipitation of calcium carbonate from mineral-rich water, indicating a likelihood of limestone being present beneath. This limestone formation process is common in hot spring environments.

The rock that probably lies beneath the travertine deposits at Mammoth Hot Springs in Yellowstone National Park is limestone.

This is because travertine is a type of limestone that forms from the precipitation of calcium carbonate from mineral-rich water, commonly seen in hot spring environments.

Limestone is a sedimentary rock made primarily of calcium carbonate, matching the process that results in travertine formation.
