B) Tend to resist any kind of motion.
C) Tend to sink into denser materials.
Answer: Tend to float on denser materials or rise up through denser rock or water or air
Explanation: buoyant materials like the crust are known to float on denser mantle. Also hot water will necessarily rise to the top allowing cold water to travel to the bottom
induced currents in power grids
extreme auroras
damage to satellites
all of the above
T
F
The correct answer is - False.
By the year 2050, which is relatively close, the population on the European continent will not be larger than what it is nowadays, but in fact, the population will be shrinking. In the present, Europe's total population accounts for little more 739 million people, while in 2050, the population will drop to around 706 million people according to the estimates.
If the projection for the European population turns out to be accurate, it means that the continent will have 33 million people less, and that is an equivalent of the populations of Greece, Belgium, and the Czech Republic combined, or rather like these three countries were left totally empty.
The downfall in Europe's population is mainly a result of the very low fertility rates in all countries, apart from the Republic of Ireland, Albania, and the recently formed Kosovo.
Heat causes the most deaths per year on average in the United States, despite the increased frequency and intensity of other weather events like hurricanes.
In terms of the weather event that causes the most deaths per year on average in the United States, the answer would be B. Heat. Although hurricanes, flooding, and lightning can also lead to fatalities, heat-related incidents lead to a higher death average over time. This is due to factors such as heat waves causing heat strokes, which can be lethal if not treated promptly and appropriately. While hurricanes have indeed increased in frequency and intensity as observed in the 2020 season, they still do not account for as many deaths as those caused by extreme heat.
Hurricanes cause the most deaths on average per year in the United States. The frequency, intensity, and duration of hurricanes have been increasing since the 1980s. In 2020, the hurricane season was the most active on record, with 30 named storms hitting the U.S. coastline and causing significant damage. Together, these storms caused more than $40 billion in damage (National Oceanic and Atmospheric Administration, 2020).
