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

Why are seismologists interested in the possibility of the two faults being connected together?.
Seismologists are interested in the possibility of the two faults being connected because it can pose a risk of earthquakes with a larger magnitude.
What impact can be caused by connecting two faults?According to the research result of seismologists which was published in an article on the official website of weather.com, the impact that can result from the connection of the two faults is the possibility of an earthquake with a larger magnitude at some point in the future. This refers to the findings of seismologists from the University of California Berkeley who have conducted research using satellite data for 20 years which later found that there are two Californian Fault Lines, especially the Calaveras Fault and Hayward Fault which are connected.
According to Estelle Cahussard, lead researcher at the University of California Berkeley, the connection of these two faults has the potential for an earthquake if a rupture occurs. It is more likely that an earthquake will occur in California´s Bay Area then it can also be felt in nearby cities. The possibility related to the magnitude of the earthquake magnitude when the two faults are connected depends on where the rupture goes so that it can result in around 7+ earthquakes.
Furthermore, research is carried out to estimate the magnitude of certain points along the fault line so that security preparations can be adjusted for the safety of people.
In conclusion, seismologists are interested in the possibility of the two faults being connected because it can pose a risk of an earthquake with a larger magnitude and further research is needed to make adjustments to security preparations to save people from the possibility of this disaster.

The correct answer is option C.
The lithospheric plates collide at the a convergent plate boundary.
What are convergent plate boundaries?
Convergent boundaries or convergent plate plate boundaries are the regions where two lithospheric plates or plate tectonics interact with each other.
The phenomenon of lithospheric plates collision occurs at the subduction zones where pone plate moves under the other plate.
In general, as a result of subduction trenches are formed which are several meters in depth.
To put it simply, when two plate tectonic converge with each other, the dense plate slides down the upper less dense plate and results in the formation of trenches also called dipping zones.

The cause of europe's mild climate is A) proximity to the mediterranean .So, correct option is A.
Europe's mild temperature can be actually attributed to two main factors:
1. Its proximity to water.
As Europe is surrounded by the Atlantic Ocean, the Mediterranean Sea, and other bodies of water, the temperatures on land are less extreme. In other words, they have milder winters and milder summers.
2. The Gulf Stream.
The Gulf Stream is an ocean current than actually brings warm water from the South and the Central Atlantic Ocean towards the European continent. This means that the ocean water surrounding Europe is relatively warm, thus regulating the temperature even more.

Wet igneous rock melts at a lower temperature than the dry version of that same rock because the addition of volatiles in "wet" rocks lowers their melting temperature.
What is volatiles?Volatiles include nitrogen, carbon dioxide, ammonia, hydrogen, methane, sulfur dioxide, water, etc.Volatiles are easily vaporizable substances present in magmas, such as H2O and CO2, whose vapor pressure is high enough that they accumulate in the gas phase that forms.Volatile means that a substance boils at a low temperature and changes from a liquid to a gas phase. Substances that are gaseous at room temperature are highly volatile.They have high volatility. It can only be considered liquid when exposed to low temperatures or high pressure.

Fossils present in ______ layers of rock are older, according to the principle of superposition.
Fossils present in lower layers of sedimentary rock are older, according to the principle of superposition.
According to the principle of superposition, in a sequence of sedimentary rocks that has not been distorted, each layer of rock is older than the layer above it and younger than the layer below it. As a result, the youngest rocks are at the top and the oldest rocks are at the bottom of a series.
One of the geological laws that geologists use to calculate the relative ages of rock strata or layers, is the law of superposition. According to this theory, rock layers are stacked or deposited one on top of the other. The bottom will have the oldest rock strata and the top will have the youngest.

Giuseppe Mercalli is credited as the creator of the modified Mercalli intensity scale, sometimes known as the Mercalli scale.
The scale is employed to quantify earthquake damage. People waking up, furniture shifting, and objects becoming damaged are all important components of this scale. Because the scale is dependent on the witnesses, it is thought to be less effective in remote regions. The overall damages are rated on the Mercalli scale from I to XII.
Seismic waves are recorded by seismographs. The "size" or amplitude of the seismic waves produced by an earthquake source and detected by seismographs is a measure of an earthquake's magnitude. (The section on seismic waves describes the types and characteristics of these waves.) Due to the wide variation in earthquake size, a mathematical technique must be used to compress the range of wave amplitudes reported on seismograms for comparison.

Lithospheric plates move in the asthenosphere due to the rising and sinking of materials.
First, the decomposition of radioactive elements causes heat in the interior part of the Earth. Then heat moves to the core. After that, heat slowly rises to the mantle and creates a convection current. Then lithospheric plates move in the asthenosphere due to the rising and sinking of materials. And finally, the process repeats as a cycle. That is the correct order of how convection current happens.
What is Convection Theory?Convection Theory was put forward by Arthur Holmes and Harry H. Hess and then further developed by Robert S. Dietz.
The evidence underlying the Convection theory is the result of research on the age of the seabed which proves that the farther from the mid-ocean ridge, the older the rock is. This means that there is a movement originating from the mid-oceanic ridge region in the opposite direction due to the influence of convection currents originating from the layer beneath the Earth's surface.

Burial metamorphism happens while sediments are buried deeply sufficient that the warmth and strain purpose minerals to start to recrystallize and new minerals to grow, however does now no longer depart the rock with a foliated appearance. As metamorphic strategies go, burial metamorphism takes location at notably low temperatures (up to ~300 °C) and pressures (100s of m depth).
