Answer:
they have similar reactivity
Explanation:
they are both in the same group so that means they have the same amount of valence electrons they shoudl have different amount of electron shells sodium would be more reactive by a little bit.
Sodium (Na) and Potassium (K) are found in the same group on the periodic table due to the fact that they have similar reactivity. Thus, option 'similar reactivity' is the correct option.
Why are sodium (Na) and potassium (K) in the same group on the periodic table?Group 1 of the periodic table contains the highly reactive chemical elements sodium and potassium. As a result of having their valence electron in the outermost s orbital, they are s-block elements.
Because they may be combined to create a wide range of chemical compounds, sodium and potassium are both extremely valuable chemical elements. Since sodium and potassium are two separate chemical elements, there are variances between them.
The size of sodium atoms vs potassium atoms is the primary distinction between the two elements. As a result of being in the same group on the periodic table, they have many things in common.

Your answer is → Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.
Answer:
Greenhouse gases have far-ranging environmental and health effects.
They can cause climate change by trapping heat, and they can also
contribute to respiratory disease from smog and air pollution. Strong cases of
weather, wildfire increase, and food supply shortage--these are other effects
of climate change by the causing factor; the greenhouse effect.

Geologists have located both oil and natural gas underground in the central United States. Oil and natural gas form from the remains of tiny sea organisms. The remains are buried in ocean sediments and slowly change to fossil fuels over millions of years. The central United States must have been covered by seawater at some point in the past. The correct option is D.
Why are coal mineral oil and natural gas called fossil fuels?Since fossil fuels are not renewable, their supply is finite and will eventually exhaust. Because they were created from the decay of plants and animals that lived millions of years ago, fossil fuels get their name.
Engineers, chemists, and geologists search for geological formations that frequently trap petroleum. They search for subterranean rock formations that may have contained crude oil using a technique known as "seismic reflection."
Thus, the ideal selection is option D.

Describe this change and explain the possible economic benefits for the city
Answer:
City centres and the benefits of agglomeration
The primary gain for business of locating in a city centre is proximity, or agglomeration, and this offers three main benefits to businesses locating in city centres. These are:
The ability to share inputs and infrastructure, such as roads, rail and street lights
The ability to recruit from a deep pool of workers with relevant skills
The ability to exchange ideas and information, known as ‘knowledge spillovers’
While the first two benefits operate over a city wide level – a business based on a business park has access to the same potential recruits as a city centre business – the third operates over a much smaller geographic area.3 It is this third factor which is so important to the services-based knowledge economy: knowledge is best spread via face-to-face interactions and these face-to-face interactions are more likely to occur over much smaller distances in more dense areas, where both formal and informal meetings are more likely to come about. Within a city, this area is the city centre.

Why tides pass over all world? Other effects of this phenomenon
Answer:
Because the gravitational pull of the moon is weaker on the far side of the Earth, inertia wins, the ocean bulges out and high tide occurs. As the Earth spins, different areas of the planet face the moon, and this rotation causes the tides to cycle around the planet. The moon's gravitational pull is the primary tidal force. The moon's gravity pulls the ocean toward it during high high tides. During low high tides, the Earth itself is pulled slightly toward the moon, creating high tides on the opposite side of the planet.
