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.
What is the thermocline?
beneath 200 meters, ocean water cools at a constant rate of 1°C per 100 meters depth
the ocean area near the polar regions where water temperatures cool
where magma is forced up through the ocean floor along mid-ocean ridges
the area off the continental shelf that declines to the ocean floor
Answer:
Beneath 200 meters, ocean waters cools at a constant rate of 1°C per 100 meters depth.
Explanation:
The ocean water is with the same characteristics throughout all of the oceans. The differences come in differences in temperature, density, salinity, etc. When it comes to temperature, it is what influences the other characteristics, and it is what causes the movement of water in the oceans.
The movement of ocean water occurs because in some parts, the ocean water gets cold, while in others it gets warm. The cold water drops deeper and moves toward the less dense warmer water, and as it gradually warms up itself it rises, pushing the warm water in opposite direction. The water is mixing at the surface, but this is not the case below 200 meters of depth, where water mixing stops. This zone, where the water is not mixing, is known as the thermocline and exists as such throughout all of the oceans.
The fastest flow is on the inside of a meander bend. True or false
Answer:
True.
Explanation:
Because when the water flows faster it has more power to erode the outside bank. The outside bend of the meander becomes deeper, reducing friction and allowing for even faster flow of water, which in turn means more erosion. On the inside bend of the meander the river is flowing much slower.

If you could travel in time and visit the park shown on the map 100,000 years in the future, what changes do you think will have taken place to the elevations of Goodnight Peak and Brushy Butte? Explain your answer.
Answer:
erosion by wind and water will help the peaks to become smaller.
If we could travel time and visit the park shown, the changes will be that the reduction of the peaks' heights will be aided by wind and water erosion.
What is soil erosion?The soil fragments are loosened or washed away during this process in valleys, oceans, rivers, streams, or far-off areas. Due to human activities like agriculture and forestry, this has gotten worse.
The process of soil eroding is ongoing and can happen slowly or rapidly. As a result, there is ongoing topsoil loss, ecological harm, soil collapse, etc. The wearing away of the top soil layer is known as soil erosion. It contributes to soil degradation. The dynamic action of erosive factors, such as water, ice (glaciers), snow, air (wind), plants, and animals (including humans), is what causes this natural process. These factors determine the agents that cause erosion, which can be classified as water erosion, glacier erosion, snow erosion, and wind erosion.

Every financial year can have a budget that includes data on the projected value of sales and estimated value of costs. You can deduce how the upcoming accounting period is likely to end from this. Compared to this suggested plan, the company's actual performance can be evaluated.
Depending on whatever area of the business needs to be prioritized, several budgets can be developed. Below are three common categories of budgeting plans.

Which of the following is NOT a reason why birth and death rates are high in developing countries?
No birth Control
Religious restrictions
Economic factors
easy access to medical care
Answer:
Easy access to medical care is not a reason for high birth and death rates in developing countries.
Explanation:
A big portion of the developing countries tends to have high birthrates and high death rates. The reason for this are numerous, ranging from political, religious, traditional, economic, low education levels, women being discriminated against, etc. In general, it seems that the lower the status of women is in a society, the higher the birthrates are, and all of the factors that contribute to it actually result in a shorter life span for the whole population.
One thing that doesn't contribute to this is easy access to medical care. Easy access to medical care is not something that is found in a developing country, on contrary, the access to medical care is hard, limited, and for many people out of reach. When medical care is not available for the population the results are always devastating, with high death rates among infants, during birth (both mothers and children), diseases spread very easily and have a much bigger impact, and because of lack of it also the population leaves shorter lives.

what is the greenhouse effect in 3 sentences simple terms? do not copy from the internet.
Answer:
Explanation:
Ok
Answer:
What is the greenhouse effect?
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere.Light energy emitted by the sun warms the earth's surface, which reflects the energy as heat that warms the atmosphere. Much of the heat is captured by greenhouse gas molecules such as water, carbon dioxide, and methane.Radiatively active gases (i.e., greenhouse gases) in a planet's atmosphere radiate energy in all directions. Part of this radiation is directed towards the surface, thus warming it. The intensity of downward radiation – that is, the strength of the greenhouse effect – depends on the amount of greenhouse gases that the atmosphere contains. The temperature rises until the intensity of upward radiation from the surface, thus cooling it, balances the downward flow of energy.* 100 * points for pick up line and will mark b

When traveling, judging the date of
arrival can be difficult for locations
A. close to the Date Line
B. near the Equator
C. near the Prime Meridian
D. during the summer
Answer:
The date can be hard for judging close to the Date Line.
Explanation:
The world is divided into meridians, which are also used for setting up time zones. The time zones are set up on every 15 degrees of longitude. All of them can be problematic when it comes to time if we travel between time zones. This is due to that if we travel between time zones we lose or gain hours, depending do we travel east or west.
One of these lines is problematic in particular because it is not just the time but also the date that can change by crossing it. That line is the Date Line. This line is located on the opposite side of the Prime Meridian, stretching north to south across the Pacific Ocean. This is the line when each new day starts, so not just the time but the dates start here as well. Basically, by going across this line, not just an hour that can be lost or gained, but a day can be lost or gained as well.
