Considering the situation of Alexander, the maximum amount he can contribute to a traditional IRA for 2020 is "$6,000" annually.
This is because, according to Internal Revenue Service (IRS), the annual contribution limit for 2019, 2020, 2021, and 2022 is $6,000.
However, for individuals 50 years and above, the annual contribution limit is $7,000.
Given that Alexander is only 43 years, therefore, the maximum amount he can contribute to a traditional IRA for 2020 is "$6,000" annually.
Hence, in this case, it is concluded that the correct answer is "$6,000."

explain how water erosion by groundwater can form a cave
Answer:-
Working slowly over many years, ground water travels along small cracks. The water dissolves and carries away the solid rock gradually enlarging the cracks, eventually forming a cave. Ground water carries the dissolved minerals in solution. The minerals may then be deposited, for example, as stalagmites or stalactites.

5. The point in Earth's interior where the energy release of an earthquake occurs is the:
A. Focus
B. Epicenter
C. Shadow zone
The point within the earth where the fault rupture starts is called the focus or hypocenter. This is the exact location within the earth were seismic waves are generated by sudden release of stored elastic energy.
The point in Earth's interior where the energy release of an earthquake occurs is the focus. The correct option is a.
What is an earthquake?An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular period. The seismicity at a particular location on the Earth is the average rate of seismic energy release per unit volume. The word tremor is also used for non-earthquake seismic rumbling.
At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground.

Describe the impact of urban growth on the environment and the problems associated with urban decay.
Answer:
Impact of urban growth on the environment and the problems associated with urban decay:
Urban growth has led to the degradation of the environment. With more and more urban development, pollution has become a major problem.
Urban growth means more traffic which in turn leads to more pollution. The rising pollution has an adverse impact on the environment and also causes may health hazards.
Urban decay has also become common where people move from one city to another in search of employment and better standard of living.
Urban decay gives rise to wastelands and also misuse of natural resources that are already limited.

what most likely led to the formation of the north american continent?
Answer: The settlement of the Americas.
Explanation:
The settlement of the Americas is widely accepted to have begun when Paleolithic hunter-gatherers entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the Last Glacial Maximum (26,000 to 19,000 years ago). These populations expanded south of the Laurentide Ice Sheet and spread rapidly throughout both North and South America, by 14,000 years ago. The earliest populations in the Americas, before roughly 10,000 years ago, are known as Paleo-Indians.
Answer:
What MOST likely led to the formation of the North American continent? Earthquakes broke large pieces off the edge of the continent. The tectonic plates sank into the ocean, making way for new continents to form. Hurricanes caused floods that submerged much of the continent.

The Earth's crust is principally composed of _______. A. Granitic and sedimentary minerals b. Granitic and basaltic minerals c. Basaltic and sedimentary minerals d. None of the above.
Answer:
Option B is correct.
Explanation:
One of the most common rock forms is granite that is found in abundance in the earth's crust. The common minerals in the granite that are found in earth’s crust are – quartz, mica, hornblende and fledspar. Basalt is a volcanic rock that forms after the cooling of lava. After weathering, the basalt is broken down into small fine pieces known as soil. Soil is the topmost layer of the earth crust and hence The Earth's crust is principally composed of both granite and basalt minerals.
Option B is correct.

Find the length of the midsegment based on the diagram below
Answer:
42
Explanation:
so like the 1 part of the triangle 1 and so the bottom of the triangle has to be the same. And the height is 9.
Answer:
C. 21
Explanation
In this triangle, 4n + 9 is the midsegment.
According to the Midsegment of a Triangle theorem, 4n + 9 is equal to half of 14n.
14n/2 = 7n
7n = 4n +9
-4n -4n
3n = 9
/3 /3
n = 3
4(3) + 9 = 21
Therefore the answer is C

based on your answer in part A what role does gravity play in the separation of the liquids shown
Gravity plays an important role in the separation of liquids because it determines the volume of liquids, and therefore, it affects the density.
When you mix different liquids they often separate forming defined layers. This process is possible due to the differences in density (mass/ volume). In this way, the liquid with a lower density will float over the liquid with a higher density.
This phenomenon is affected by gravity or the force that makes everything on the Earth to be pulled towards the center of it. This is because gravity exerts pressure over bodies and affects the volume, which is one of the factors that determines density.
