Answer:
B. isotopic dating of meteorites from the first differentiated bodies of the Solar System.
Geologists estimate that the Earth is 4.54 billion years old, based on isotopic dating of meteorites from the first differentiated bodies of the Solar System. The response is option B.
How does meteorites tells the age of solar system?The first solid substance to develop in our solar system can be found in some so-called "primitive" meteorites. The age of this substance, 4.568 billion years, has been used to calculate the age of our solar system. Many ancient meteorites have practically not altered since they were created.
More than 4.5 billion years ago, when the solar system was still young, dust and other microscopic particles that eventually combined to create asteroids gave rise to chondrites. Chondrites are essential to the investigation of the solar system's origin, age, & composition because they developed at the same time as the solar system.

Which of the following is correct about floodplains? Which of the following is correct about floodplains? Floodplains are not associated with deposition. They are generally filled with layers of alluvium. Despite the name, they are rarely subjected to flooding. They are well drained throughout. They are an erosional feature located within a depositional feature.
They are generally filled with layers of. the following is correct about floodplains. Thus option (A) is correct.
What are floodplains?A bottomland, floodplain, or floodplain is a region of land next to a river that runs from the channel's banks to the foot of the valley's surrounding walls and is subject to flooding during times of high discharge. The soils are typically made up of clays, silts, sands, and that have been left behind by floods.
Floodplains frequently have high soil fertility because regular flooding can deposit nutrients and water; some significant agricultural regions, such as the Mississippi river basin and the Nile, heavily rely on the floodplains.
The Mississippi River has a large floodplain covering large portions of midwestern states through which it flows. Ninety percent of this area is no longer flooded annually due to levees designed to hold the water back.
Therefore, option (A) is correct.

Please select the best answer from the choices provided.
Answer:
The Answer is D.) an architectural design favored by French immigrants to the US
Explanation:
Answer:
D
Explanation:
Porosity increases:_________. a. when grains settle more closely together after deposition.b. with increasing crystallization between grains in sedimentary rock. c. with the cementing of sediments by minerals from groundwater. d. when rocks develop joints or fractures.
Answer:
The correct solution is Option d (when rocks develop joints or fractures ).
Explanation:
Porosity is observable from descriptive samples taken. The drawbacks of receivable dams are that this is impossible to make true reflection temperature measurements, specific side-wall concrete samples while being often valuable can also result in poor coverage as well as dependence on log-derived porosity seems to have become the standard.As porosity rises, too much wind needs to pass further through most of the shelterbelt, which would be to say the less significant decrease in wind direction.Some other available scenarios have no connexons with the particular circumstance. So this seems to be a reasonable option.

The correct statements are that-
Soil condition directly affects the crop growth.Soil is used faster than it is replaced.The soil cannot be replaced in a short time.The destruction of soil can take just minutes.The correct set of options that match the statements above are as under 1, 2, 3 and 5.
Soil
If the soil is infertile, there will be poor or no growth of crops. If the soil condition is healthy, the crop growth will be good. The soil replacement takes place gradually over a period of time due to natural events like wind, rain, etc. The amount of soil on Earth is limited at a given point of time. Due to deforestation, the amount of soil is also getting reduced. Destruction of soil can happen due to natural calamities like landslides, earthquakes, etc.Hence, the statements as under 1, 2, 3 and 5 are correct about the characteristics of soil.

Describe how voting changed in America from the early days to the present.
Hey there! I'm happy to help!
There are many ways that voting has changed in America. When America was founded, only property-owning white males could vote.
During the end of the 18th century to about the mid-1800s the part that you had to own property was removed.
In 1870, the 15th amendment was passed, which allowed males of all races to vote.
In 1920, the 19th amendment gave women the right to vote.
Decades later, the 23rd amendment let residents of Washington D.C. vote.
The 17th amendment also let the people choose who their Senators would be, not the Legislature.
