Nuclear power plants produce radioactive waste that must be stored properly.

Nuclear power plants are thermal power stations in which power is generated and the heat source behaves as a nuclear reactor.

It is not possible for a nuclear power plant to produce zero waste because a lot of chemicals are utilized to create the process in order for it to give energy to other machines.

Radioactive waste cannot be released into local water supplies because the wastes are very harmful in nature and may cause mutation in the aquatic life which will affect humans adversely as well. Air pollution is also a result of the chemicals not being stored properly.

Volcanoes on the ocean floor erupt to create oceanic islands, often referred to as volcanic islands. Oceanic islands are also called as "high islands," regardless of their height. Low islands are continental and coral islands, which can be hundreds of metres taller than high islands. Even though they are encircled by water, continents are not categorised as islands because of their size. The smallest continent, Australia, is more than three times larger than the largest island, Greenland. In every ocean, lake, and river in the world, there are innumerable islands.

Answer:

Rome’s geography protected the city from invaders.

Rome’s central location made it a center for trade throughout the Mediterranean.

Rome’s lack of natural resources encouraged expansion.

Rome’s distance from Greece protected its culture from Greek influence.

Answer:

B and D

Explanation:

The statement that is true given the observed average distance between galaxies today is that the faster the past expansion rate, the younger the age of the universe. Option a is correct.

According to Hubble's Law, the speed of galaxies receding from us is proportional to their distance from us. Hence, a faster past expansion rate implies that the galaxies were closer together in the past.

If we run the clock backwards and extrapolate from the observed rate of expansion, we find that the universe must have been hotter and denser in the past. This ultimately means that the age of the universe is younger, since it has taken less time for the universe to expand from its past density and temperature to its current state.

Therefore, a is correct.

The Number of paces taken by Mark is more than required, hence, the reason he ended up in a different location.

The actual direction = 45 degrees

This means that using a compass clinometer, the location is in the north east direction (NE)

THE distance = 200 feets

Mark's pace = 2.7 feets per steps

Number of paces = 540 paces

Distance covered = speed per pace × number of paces

Distance covered by Mark = 2.7 × 540 = 1458 feets

The number of paces he should have taken :

200 feets / 2.7 = 74.07 paces

Mark should have taken about 74 paces.

Hence, the Number of paces taken by Mark is more than required, reason why he ended up in a different place.

Solar heating primarily affects the surface temperature and climate of the Earth but has minimal impact on the deep interior processes. Background thermal heating from residual "Big Bang" energy is negligible compared to the other heat sources.

a) the kinetic energy of the colliding planetesimals:

During the early stages of Earth formation, numerous planetesimals, or small celestial bodies, collided with the proto-Earth. The kinetic energy of these collisions generated enormous heat and contributed to the differentiation process.

b) Radioactive decay of natural radioactive elements:

Radioisotopes found in the Earth's interior, such as uranium, thorium, and potassium, undergo radioactive decay, releasing heat as a byproduct. This heat from radioactive decay played a key role in warming the Earth's interior early in Earth's history and aided the process of differentiation.

c) Compressive heating with increasing mass of the Earth:

As the proto-Earth accumulated mass through the accumulation of planetesimals and gravitational attraction, compressive heating occurred due to the increased pressure. This process made the Earth's interior hotter and easier to distinguish into different compositional zones.

Explanation:

Nuclear and Fossil fuel-burning power plants are thermal power stations that produce heat to make steam to spin a generator and generate electricity. They differ mainly in where their energy comes from; a nuclear reactor produces heat from radioactive metals, and a fossil-fuel plant burns coal, oil, or natural gas.

Nuclear power plants turn a small amount of (different) nonrenewable rock into power and solid pollutants that can be contained quite reliably, with (especially compared to the power produced) very few exceptions.

Fossil fuel-burning power plant turns a large amount of nonrenewable rock (and oil) into power and pollutant gas that can’t easily be contained and gets out into the environment.

The advantages of nuclear power are they are low-carbon energy sources, reliable and cost-effective, and essential to our response to climate change and greenhouse gas emissions, whereas, for fossil fuel-burning plants, they are easy to install, highly efficient and reliable, currently wide availability, an abundance of fossil fuel sources.

The disadvantages of the nuclear power plant are nuclear waste, malfunctions can be catastrophic, and very high upfront costs, whereas, in the case of fossil fuel burning plants, they are unsustainable, incentivized, release vast amounts of harmful byproducts called greenhouse gases (especially carbon dioxide (CO2)), into the atmosphere and non-renewable.

During the ice crystal process of rain formation, ice crystals grow larger at the expense of the surrounding liquid cloud droplets (water droplets). This is option B.

The process that causes the cloud formation is called condensation. When air contains as much water vapor as it can hold, clouds are formed.

Note that condensation by itself doesn't cause rain formation. For moisture in clouds to succumb to gravity and return to Earth's surface, it must become heavy (large) enough.

Ice crystals and water droplets exist side by side in cold clouds. Because of an imbalance of water vapor pressure, water droplets transfer to ice crystals. Eventually, these crystals grow heavy enough to fall to Earth's surface.

Answer: Due to climate in Australia their water resources often dry up. The largest river in Australia is Murray & it has two tributaries of Darling & Murrumbidge. It has several salty lakes including Eyre, Torrens, & Gairdner. There is groundwater that people can use for drinking water.

New Zealand has many rivers that have a short flow & are suitable for hydropower potential. Rivers on the Western side of the spring form waterfalls. On the East coast of the river originate from glacier lakes. Here lies the longest river Clutha.

Explanation:

Australia's climate causes its water resources to frequently run out. The Murray River, which is the largest river, has two tributaries, the Darling and the Murrumbidge. Eyre, Torrens, and Gairdner are just a few of the lakes that are saline. People use groundwater as a source of drinking water.

There are numerous rivers in New Zealand with short flows and potential for hydropower. Waterfalls are formed by rivers on the spring I's western side. The river's east coast contains lakes that were formed by glaciers. Clutha, the longest river, is located here. On the North Island, there are rivers called Waikato and Whanganui. In New Zealand, there are many lakes, with Lake Taupo being the biggest.

Natural sources of water that could be used by humans as a source of irrigation or drinking water are known as "water resources."

Only 3% of the water on Earth is fresh water, and 97% of that is salt water, with slightly more than two thirds of it frozen in glaciers and polar ice caps.

Therefore, Australia's climate causes its water resources to frequently run out. The Murray River, which is the largest river, has two tributaries, the Darling and the Murrumbidge.

The thinnest sediment layer in the oceans is found on mid-ocean ridges. Hence, option C is correct.

With a length of about 65,000 kilometers (40,390 miles) and more than 90% of the mountain range submerged in the deep ocean, the mid-ocean ridge is the largest chain of mountains on Earth.

Mid-ocean ridges are formed along divergent plate borders as the Earth's tectonic plates separate, creating new ocean bottom. As the plates separate, molten rock rises to the seafloor, causing enormous basalt volcanic eruptions. The rate at which a ridge expands affects the shape of the ridge; slower spreading rates produce steep, irregular topography, whereas faster spreading rates provide more wider profiles and softer slopes.

A system of seabed mountains called a mid-ocean ridge (MOR) was created by plate tectonics. It normally rises around 2,000 meters (6,600 feet) above the lowest part of an ocean basin and is roughly 2,600 meters (8,500 feet) deep. This feature represents the location of a divergent plate boundary where seafloor spreading occurs.

Answer:

a subsistence farmer produces enough for his own family but has little surplus

Answer:

A flawed reactor.

Explanation:

The management of the facility was interested in determining if, in the case of a total loss of power, the electrical generator's turbines would continue to spin long enough to keep the cooling pumps running until the diesel backup generators began to operate.

The emergency core cooling system of the reactor was turned off. Due to operator mistake, the reactor's power was reduced to a very low output level. Control rods were removed from the reactor to boost its output because it started operating at a low efficiency. As a result, the reactor became unstable.

Then, the power-producing turbines were turned off. The cooling pumps in the reactor slowed down as a result. Boiling of the coolant began. Power output increased sharply when the reactor began to overheat. The reactor partially burst, preventing the control rods from being put back in. At that moment, the reactor was completely toast. Adios muchachos, the Second Coming couldn't have stopped the reactor's total devastation as a result of the numerous steam and hydrogen gas explosions that occurred.
