Answer:
The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption.
What is the biggest obstacle to traveling by boat on the Congo River?
A.
the many cataracts
B.
the unusual path of the Congo River
C.
shallow areas due to drought
D.
the river's narrow width
The biggest obstacle to traveling by boat on the Congo River is A. the many cataracts
The numerous cascades on the Congo River are the main challenge for boat passage. Navigation on the Congo River is challenging and dangerous due to a number of strong cataracts, or rapids and waterfalls. The hills and troughs in the riverbed that force the water to flow quickly across them are what generate these waterfalls.
On the Congo River, there are a total of seven major cataracts that make navigation extremely difficult and demand that boats be unloaded and portaged around. There are also shallow places brought on by the drought. Because of the ideal growing conditions provided by these shallow locations, the water plants flourished, producing troublesome obstructions for the boat.

How would human activities affect the migration of animals like the Christmas crabs in Australia?
Answer:
Most of Christmas Island's adult red crabs begin their breeding migration to the sea as soon as the wet season rains have established. But we can never be sure when the wet season is going to begin!
The crabs' breeding timetable is fixed around the phases of the moon. Spawning (the dropping of their eggs into the sea) must occur before sunrise on spring tides during the last quarter of the moon, regardless of any other factor. The timing of spawning is the only certain and predictable part of the whole migration; all other stages of the migration will vary with the prevailing weather.
The crabs will start their migration if there is enough time for them to complete their downward migration, mate and develop eggs before the next suitable spawning date.
The red crab breeding migration comprises a series of separate actions on the crabs' part that follow on from one to the other in a programmed sequence. These separate actions in combination make up the breeding migration and one action will not occur unless the preceding action is accomplished. If there isn't enough time for them to be able to do all of these things before the next spawning opportunity, they will delay the start of their migration and attempt to meet the following month's spawning date.
The first action that occurs is movement of crabs to the sea. The largest mass movement of crabs takes place in this first downward migration. Males farthest inland start this movement and are progressively joined by more and more crabs (both males and females) as the movement progresses toward the sea.
When the crabs arrive at the shoreline, they dip in the sea to replenish body moisture and salts. The male and female crabs then move back on to the shore terraces where the males dig burrows for mating. Mating takes place and then the males again dip in the sea and then they will start their return migration.
The females remain behind in the mating burrows to brood their eggs. This takes a couple of weeks. A day or two before the spawning date the females emerge from the breeding burrows with ripened eggs and move to the shoreline where they again dip in the sea and then retreat to shade.
Before the turn of the high tide and just before dawn the females will again move to the waterline and around the turn of the tide they will drop their eggs into the sea. After they have jettisoned their eggs the females commence their return migration.
The next phase of the breeding migration takes place in the sea. The eggs that the females drop into the sea hatch immediately into larvae. They grow through several larval stages into tiny prawn-like animals called megalops. After about four weeks the megalops emerge from the sea and they moult into baby crabs. The baby crabs then move inland and settle at suitable localities. The successful emergence of baby crabs is unpredictable but is incredible when large numbers emerge. Some years very few, or none, emerge. After about four years growth crabs will take part in the breeding migrations and the life cycle continues.
If the rains stop or peter out, the crabs will delay the start of their migration, or, if they have started migrating, they will stop moving and stay wherever they are until the rains begin again. It is rare that substantial rains will begin early enough in the year for a spawn during the last lunar quarter in October - but it has happened! Spawning in November or December are the more usual, which means that rain must commence in the preceding month and continue.
All phases of the crabs' breeding migration involve colossal numbers of crabs and usually occur all over the island. If the rains continue, there is usually a second, and sometimes even a third, smaller, downward migration by crabs that did not join in the first migration. When this happens it is possible to see crabs on return journeys mingling with the crabs on their downward migration. It can become confusing for all concerned! We are sorry that we can not be more explicit about the timing of the start of the red crab migrations, but the weather as you know cannot be accurately predicted. The best advice we can give is to be at Christmas Island during the last quarter of the moon in either November or December for the best chance of seeing something interesting happening in the annual red crab migration. If you are able to arrive earlier and to stay longer the more parts of the migration sequence you will be able to experience.
Explanation:
Which event was a major source of atmospheric oxygen?
photosynthesis
volcanic eruptions
decomposition of water
outgassing
Answer:
Photosynthesis was a major source of atmospheric oxygen.
Explanation:
Earth's atmosphere was not the same as it is in the past. For a larger portion of Earth's history, the atmosphere actually didn't have an atmosphere or the one it had was not suitable for complex lifeforms to develop. This all changed because of one major event, the process of photosynthesis.
Initially, it was the cyanobacteria that started to use this process in order to produce their own food and energy. Basically, this process meant that the cyanobacteria, and a lot of later organisms, were taking in carbon dioxide, use it for their own needs, and release the oxygen. The oxygen was released into the ocean and into the atmosphere, which resulted in a gradual change in the composition of the atmosphere to a degree where it was suitable for larger organisms to start to develop.
People consume different kinds and amounts of food, depending on their location, activities, and available food resources.
Dietary needs and the consumption of vital nutrients varies between developed countries and developing countries.
Explain how developed and developing countries differ in food consumption and diet.
Answer:
the difference is in the nutrition of the food in developed and developing countries.
Explanation:
assumed that a country with a very low anual income or the per capita having a very low value might not have the fortune to have the consumption of every nutrient possible in there daily meal. whereas in compared with the developing countries every people is sufficient and literate and much familiar with the quantity and quality consumption so and we can see that this is the first difference between the consumption of different people in countries of two face.
Answer:
Food consumption in developed and developing countries vary in quite a few ways. There are a few reasons for this, such as income, capita having low value, and population. A country with a low annual income might not be able to buy imported goods because they are too expensive. If a developing country has a large population, they may not be able to afford food for everyone to eat. A family in a developing country may also depend on farming on their own to grow their food. Whereas developed countries can get imported goods and have largely sustained farms, factories, and cattle for food. All of this can be sold in stores for people to buy and use. This means that even if the population is large, people that can afford it can go to the store and get food. All of this has an effect on diet and food consumption. If you can afford to buy food to meet your dietary needs, your diet will be very restricted and you may not get all of the nutrients you need.

What does a graph mean?A graph shows the correlation between two variables that are typically assessed along one axis of a pair at right angles.
A graph in discrete mathematics is made up of vertices a group of point and edges the lines bridging those vertices.
There are many different kinds of graphs, including connected and unconnected graphs, weighted graphs, bipartite graphs, directed and undirected graphs, and simple graphs.
Because they make information accessible and simple to comprehend, graphs and charts are effective visual aides.
Graphs are therefore often used in print and electronic media, which is not surprising. Sometimes, data can be better understood when it is presented as a chart.

worldwide destruction
(B) The US was concerned about having to enter a war with all of the Eastern
Bloc countries
(C) The USSR was concerned about having to enter war with all of the Western
Bloc countries
(D) All of the answer choices
Answer:
Neither country wanted to engage in a nuclear war that would lead to worldwide destruction.
Explanation:
The US and USSR became arch enemies soon after World War II ended, and that continued to be the case until the USSR seized to exist. The two countries became opponents and developed very bad and tense relations because they had different ideas as to how the world should shape up, but also because both of them wanted to be the only dominant power in the world.
Both countries were heavily armed and the weaponry was constantly icnreasing, with newer and better weapons constantly been created to gain an advantage. Nuclear weapons were abundant at both as well, but they never got used in an open war between them. The reason was simple, if a direct war between them occurred, there would have been worldwide destruction and everyone will lose, so that was kept as the last option in case of an attack by the other. Not to be mistaken though, these two were constantly in war with each other, not just diplomatic, but also military one, just that they used other countries as battlefields where they supported a particular side.
