Answer:
1. Why did the disaster take place?
The Chernobyl disaster took place due to a combination of design flaws, operator errors, and a lack of safety protocols. The reactor design was flawed, as it did not contain a containment structure to prevent the release of radioactive materials in the event of an accident. In addition, the operators of the reactor made a series of errors during a safety test, leading to a power surge in the reactor core, which caused an explosion and a fire.
2. When and where did the disaster take place?
The Chernobyl disaster took place on April 26, 1986, in Pripyat, Ukraine, which was then part of the Soviet Union.
3. What were the major health effects for exposed populations?
The major health effects for exposed populations were cancer, thyroid disease, and birth defects.
4. What radioactive elements were emitted in the environment?
The Chernobyl disaster released a number of radioactive elements, including iodine-131, cesium-137, and strontium-90, into the environment.
5. How was Europe affected by the radioactive fallout?
The radioactive fallout from the disaster at the Chernobyl power plant affected large areas of Europe, including parts of Ukraine, Russia, and Belarus. The radioactive materials contaminated large areas of farmland, forests, and lakes, making it difficult for local populations to access food and water. This contamination also led to the evacuation of hundreds of thousands of people from the affected areas. The radioactive fallout also had a significant impact on the health of the exposed populations, with increased rates of cancer and other health problems. In addition, the disaster had a major impact on the local economy, as the contaminated areas could no longer be used for agriculture or other economic activities. The disaster also had a lasting impact on public perception of nuclear energy, with many people becoming skeptical about the safety of nuclear power.
Evaluate the impacts of water management across national boundaries.
You may use the resources above and/or examples you have studied to support our answer
The impacts of water management across national boundaries can be both positive and negative. On the positive side, effective water management can lead to improved water quality, increased water availability, and improved water security.
Why is water management necessary and what does it entail?Water management is significant because it influences expectations for future irrigation. Water management refers to the control of water resources under predetermined rules and guidelines. Due to droughts and overuse, water, once a plentiful natural resource, is becoming a more valuable commodity.
Flooding is largely a result of deforestation, overgrazing, mining, industrialization, global warming, etc. : Large-scale irrigation projects are the greatest way to reverse this harm and defend against additional environmental risks.

how does the troposphere differ from the stratosphere? how does the composition of the troposphere change with a change in altitude? how does the composition of the troposphere change with a change in latitude?
The major differences between the stratosphere and troposphere are the concentrations of ozone and water vapour, as can be seen in the comparison of the pie charts below:
The stratosphere has much higher concentrations of ozone than the troposphere, while the troposphere has much higher concentrations of water vapour.The troposphere rises 8 to 14.5 kilometres above the Earth's surface (5 to 9 miles). The densest component of the atmosphere is located here. The most of the weather occurs here. Just above the troposphere, the stratosphere rises to a height of 50 kilometres (31 miles). Because the ozone layer absorbs the majority of the sun's UV light, the temperature of the stratosphere rises with height. Life on Earth is shielded by the ozone layer, which acts as an absorbent.

why do some igneous rocks form larger crystals than others?
Answer: The size of crystals in an igneous rock is an important indicator of the conditions where the rock formed. An igneous rock with large crystals probably indicates that the rock formed deep within the Earth, since it is typically warmer deep inside the Earth than near the surface.
which landscape feature is most likely to form a drainage divide
A mountain ridge. This is because the answer is a mountain ridge. Hope this helped.
A drainage divide is a ridge or high point in the topography of the land that separates two drainage basins, or areas where water drains into different waterways.
The landscape feature that is most likely to form a drainage divide is a mountain range or high elevation ridge.
A mountain range acts as a physical barrier, forcing water that falls on one side of the range to drain into one watershed, while water on the other side drains into a different watershed.
This creates a drainage divide that separates the two drainage basins and determines the flow of water in the region.
In addition to mountain ranges, other high elevation landforms such as plateaus, ridges, and high points can also act as drainage divides, separating and directing the flow of water in a region.
For example, a high point in the landscape can divide two drainage basins and determine the direction of water flow.

https://brainly.com/question/30525408#SPJ1Is Today’s mindset of agricultural production is to produce more with less?
The world’s agriculture industry faces a huge task. It must feed a growing world population by producing more food in the next thirty years than has been produced in the last 10,000 years.
THE SOLUTION
As impossible as it sounds, we can do more with less. And technology holds the key. In farming, as in so many other industries, digital tools and innovations are transforming traditional approaches, creating efficiencies and providing sustainable solutions.
The U.S. has been an early adopter of agricultural technology (AgTech), from big data and the internet of things (IoT) to the global positioning system (GPS) and genetic modification (GM). This readiness to adopt,[2]experts say, has led to tremendous productivity gains. Total agricultural output tripled between 1948 and 2015 – even as the amount of labor and land used for farming declined by 75 percent and 24 percent, respectively. In 1970, one farmer could on average produce food to feed 72 people. Today, that one farmer can feed 155 people.[3]Most of this is down to the adoption of new technologies.
PRECISION AGRICULTURE
Precision technologies have been the driver for future innovation in farming, enabled by the arrival of GPS and the Global Navigation Satellite System (GNSS). As the name suggests, precision agriculture makes farming practices more accurate. It uses a wide range of tools including GPS, sensors and even drones to collect, measure and analyse data to help famers better understand their land and what each individual crop needs for optimal yield.

q10: which gas had the largest proportional increase in mass when moving from the upper troposphere to the surface? why?
The gas which had the largest proportional increase in mass when moving from the upper troposphere to the surface is water vapor.
The gaseous form of water is known as water vapor, or aqueous vapor. Within the hydrosphere, it is one type of water state. Water vapor can be created by the boiling or evaporation of liquid water as well as by the melting of ice. Like the majority of other atmospheric elements, water vapor is transparent. Water vapor is produced mainly by evaporation and eliminated by condensation in a normal atmosphere. It causes convection that can result in clouds since it is less dense than the majority of the other air constituents. Each planet in the Solar System, as well as many astronomical objects like natural satellites, comets, and even massive asteroids, all contain water vapor, making it a rather frequent atmospheric component. The discovery of exoplanet water vapor would also suggest that additional planetary systems have a similar distribution. In the instance of some planetary mass objects, the presence of water vapor can also serve as a subliminal indicator of the existence of extraterrestrial liquid water.

the dead zone at the mouth of the mississippi river in the gulf of mexico is caused by the process of which results in hypoxia when the algae and phytoplankton decompose. t/f
The process that results in hypoxia whenever the algae and phytoplankton disintegrate is what leads to the dead zone near the river mouth of the Mississippi in the Gulf of Mexico. This is True.
In the oceans and lakes of the world, dead zones are areas of low oxygen content, or hypoxia. Since most species need oxygen in order to survive, only a small number of living things can thrive in hypoxic environment. For this reason, these areas are referred to as "dead zones." Dead zones are a result of eutrophication, a condition that happens when an aqueous water body gets an excess quantity of nutrients like nitrogen and phosphorus. These nutrients support the development of cyanobacteria, sometimes known as blue-green algae, at typical levels. However, when nutrients are in excess, cyanobacteria can grow out of control and cause damage. These extra nutrients are primarily washed into the ocean as a result of human activity. Therefore a dead zone can be seen frequently close to populated beaches.

The Desert is the most likely source of the high concentration of aerosols particulates that appear off the coast of northwestern africa.
Aerosols are incredibly small liquid and solid particles that are floating in the air. Aerosols include things like wind-borne dust, sea salt, debris, fire from wildfire, and pollution from factories. Aerosols have the ability to either cool or warm the surface, based on their size, kind, and position. They can encourage the production of clouds or they might prevent it. The aerosols immediately scatter sunlight back into space as a result. Aerosols in the earth's atmosphere can alter the size of clouds particles as a side effect, altering how the cloud reflect and absorb sunlight and impacting the Earth's energy balance. Aerosols can serve as catalysts for chemical reactions. The processes that result in stratospheric ozone being destroyed are the most important of these reactions.

when radiation first reaches earth from the sun, why is most of it not absorbed by the greenhouse gases before it reaches the earth?
When radiation first reaches the earth from the sun, most of it is not absorbed by greenhouse gases before it reaches the earth because some of the gas is reflected by the atmosphere so that it will reflect sunlight radiation back to the earth's surface.
Explanation of Greenhouse GasesThe greenhouse effect is an event that traps the sun's heat inside the earth so that the earth's temperature is hotter than usual.
Most of the radiation of sunlight that enters the earth will be absorbed by the earth and some will be directly reflected back by the atmosphere. But there is also some sunlight that enters until it reaches the earth's surface and then is reflected towards the atmosphere and finally out of the earth. If there are greenhouse gases in the atmosphere, these greenhouse gases will reflect solar radiation back to the earth's surface.
The more greenhouse gases there are in the atmosphere, the more solar radiation is retained on earth. This causes the surface temperature on earth to increase.
