This claim regarding radon is untrue. Modern home construction lowers the risk of radon gas buildup.

The uranium decay cycle produces the radioactive gas radon, which is a naturally occurring substance. It is an inert gas that has no flavor, color, or odor.

When uranium, thorium, or radium, which are radioactive metals, decay in rocks, soil, or groundwater, radon, a radioactive gas, is naturally produced. People can be exposed to radon mainly via inhaling radon in air that enters buildings and homes through cracks and crevices.

Lung cancer risk rises with radon exposure over time. The second most common cause of lung cancer in the US is radon.

Complete question:

Which of the following is not true about radon?

A - It is colorless and odorless and tasteless

B - Radon levels will vary depending on weather conditions

C - Levels can be reduced by installing a ventilation system

D - Modem home construction reduces the potential for radon gas accumulation

The gravitational forces from the sun and the moon are-The Sun actually exerts a stronger force on the side of the Earth nearest the Sun, and the Moon exerts a stronger force on the side nearest the Moon

The tidal effect is actually inversely proportional to the cube of the distance while gravitational force is inversely proportional to the square of the distance. Since the distance between the sun and the earth is much greater than that between the moon and the earth , the effect observed due to the moon is more than due to the sun.

Gravitational forces are considered as strong force. Due to gravitational force of moon, generally tides arises.

The width, depth, and velocity of the stream often rise along with the discharge. Position in the stream channel, abnormalities in the stream channel brought on by resistive rock, and stream gradient all affect a stream's velocity. Water near channel edges is slowed by friction.

Flooding happens when a river's discharge exceeds the volume of its channel, causing the river to overflow into the floodplain, the region next to the channel. Several things can cause the discharge to increase. The most frequent reason for floods is heavy rain. Long periods of rain cause the soil to get saturated and lose its ability to retain water, increasing surface drainage. Floods and higher discharge levels will result from rainwater entering the river much more quickly than it would if the land weren't saturated.

Answer:

True. Lotic systems, for example streams, are characterized by flowing waters.

When gases in Earth's atmosphere capture the heat from the Sun, the process is known as the greenhouse effect. Earth becomes significantly warmer as a result of this process than it would be otherwise. One of the factors that makes Earth a nice place to live is the greenhouse effect.

More heat from the Sun is being trapped in our atmosphere thanks to the accumulation of CO2 that is released during the burning of fossil fuels. Human-made actions are referred to as anthropogenic actions, and the release of CO2 is one such anthropogenic action that contributes to the current enhanced greenhouse effect.

Global warming is the gradual warming of the Earth's surface that has been seen since the pre-industrial era (between 1850 and 1900), and is attributed to human activity, particularly the burning of fossil fuels, which raises the levels of heat-trapping greenhouse gases in the atmosphere.

A location with a thinner lithosphere will have a comparatively higher regional elevation as the thick lithosphere is replaced by the less dense asthenosphere.

When the lithosphere in a certain area is heated, it expands and becomes less dense, elevating the area as a result. Because less thick asthenosphere is replacing more dense lithosphere in this instance, thinner lithosphere likewise produces greater heights.

Regional heights are largely governed by crustal thickness, although they can also be impacted by the upper mantle's material composition, temperature, and density.

Different geologic histories of different places are reflected in disparities in crustal thickness. The highest point on Earth is Mount Everest's summit, which is located in both China and Nepal.
