The net population of a country with a birth rate of 18, death rate of 5, and a net migration of -4 would be 9. This is calculated by taking the birth rate minus the death rate, and then adding the net migration rate. In this case, 18 - 5 + (-4) = 9.

The net population of a country is an important factor in understanding its current population size and possible future population growth. Birth and death rates, as well as net migration, all play an important role in determining a country’s population size.

Birth rates refer to the number of live births per 1,000 individuals in a population in a given year, while death rates refer to the number of deaths per 1,000 individuals in a population in a given year. Net migration, meanwhile, refers to the balance between the number of people moving into a country and the number of people moving out of a country.

The collision-ring theory describes how particles interact with each other and exchange energy when they collide.

Collision-ring is a type of network topology in which all devices on the network are connected in a circular or ring formation. Each device is connected to two other devices, one to the left and one to the right. Data is passed in a single direction around the ring, and each device checks the data to determine if it is intended for it. If not, the data is passed on the next device. Collision-ring is a relatively simple type of network topology that is easy to maintain and troubleshoot.

This theory states that when two particles collide, the kinetic energy of the particles is converted into a "ring" of energy that expands outward from the point of impact, allowing the particles to interact with each other over a greater distance. This ring of energy acts as a bridge between the two particles, allowing them to exchange energy even when they are not in close proximity. As the energy dissipates, the particles will eventually stop interacting with each other.

Here is a description of the graph of Brazil's percentage of urban population from 1960 to 2010:

From 1960 to 2010, Brazil's urban population increased significantly. In 1960, the percentage of Brazil's population living in urban areas was about 44%. This percentage increased steadily over the years, reaching about 85% by 2010.

The graph shows a sharp increase in the percentage of urban population in the 1970s and 1980s, which was likely due to the rapid urbanization and industrialization of Brazil during this time period. From the 1990s to 2010, the percentage of urban population continued to increase, although at a slower rate.

Overall, the graph shows a clear trend towards urbanization in Brazil over the past few decades, as more and more people have moved from rural to urban areas in search of better economic opportunities and living conditions.

The physical feature that is a convergent boundary is often associated with volcanic arcs only. Hence, the correct option is (D).

A convergent boundary or also known as a destructive boundary is an area on the Earth's surface where two or more lithospheric plates collide. In this event, one plate will usually be under another plate and this process is often known as subduction. With this subduction event, what is called a volcanic arc is created. This volcanic arc is a branch of the volcanoes that formed above the subduction plate.

Answer: The overridden plate (the slab) sinks at an angle of approximately 25 to 75 degrees to Earth's surface. This sinking is driven by the temperature difference between the slab and the surrounding asthenosphere, as the colder oceanic lithosphere has, on average, a greater density.

The viscosity that flood basalts have is low viscosity.

A flood basalt, also known as a plateau basalt, is the outcome of a massive volcanic eruption or series of eruptions that cover significant areas of land or the ocean floor with basalt lava. Black and brittle, basalt is a type of igneous rock that contains less than roughly 52 percent silica by weight (SiO2). The low amount of silica in basalt contributes to the material's low viscosity (resistance to flow). Large volumes of low-viscosity and low-gas magmas typically erupt from fissures (cracks) during flood basalt eruptions, which result in the formation of expansive plateaus that are almost completely flat. Both continents and the ocean floor are possible eruption sites for flood basalts.

During a subduction zone earthquake, Japan moves in a westward direction as the Pacific Plate is being pushed beneath it. This movement of Japan is known as the subduction zone earthquake effect.

Subduction zone earthquakes are often very large, causing intense shaking and strong ground motions. These earthquakes can also cause tsunamis, landslides, and other secondary hazards such as liquefaction and fires. Since the Pacific Plate is being pushed beneath Japan, the surface of Japan is pushed upward, resulting in a westward displacement of the land.

The kind of volcano with a broad base with gently sloping sides is a shield volcano.

A shield volcano is a volcano that, like its name, has a look that resembles a warrior's shield that is lying on the ground. It has a wide (broad base) with gently sloping sides.

The eruption of low-viscosity lava causes the shape of the volcano. The low viscosity allows the lava to travel further and form thinner flows. Repeated eruptions then eventually result in a steady accumulation of lava layers.

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. Aerosols develop into polar stratospheric clouds throughout the polar winter.

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.

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 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.

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.

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.

The characteristic of divergent plate boundaries are an oceanic ridge, shallow earthquakes, and rising magma (B, D, E)

A divergent boundary is formed when two tectonic plates begin to move in opposite directions. Magma, which is molten rock, rises from the Earth's mantle to the surface at these borders, where it cools and solidifies to form new oceanic crust. Divergent plate boundaries are identified by shallow earthquakes, volcanic eruptions, a high topographic ridge, and extremely youthful lithosphere. These characteristics can be seen on the boundary of divergent plate systems.

Both the continental and oceanic lithospheres contain examples of these boundaries. The lithosphere in these areas is forced to stretch and pull apart as a result of the presence of tensional stress caused by the interaction of two tectonic plates that are separated by a divergent boundary. Within the continental lithosphere, divergent boundaries cause the gradual growth of ocean basins.

Your question is incomplete, but most probably your full question was:

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.
