Answer:
A : 3.5 billion years ago
Approximately about 3.5 billion years ago the fossil record extend. The reason the correct option is a.
According to radiometric dating, Earth formed around 4.5 billion years ago. The oldest fossils, which are found in rocks older than 3.5 billion years (see Precambrian epoch), resemble creatures like bacteria and cyanobacteria (blue-green algae). The so-called Ediacara fauna, which consists of small, soft-bodied wormlike organisms, is where the oldest animal fossils, dating back roughly 700 million years, may be found. In rocks that are around 540 million years old, there are many fossils with mineralized skeletons that belong to several living phyla.
The oldest fossils date back between 3.48 and 4.1 billion years. A geological timescale and the relative ages of various fossils were recognised in the 19th century as a result of the discovery that specific fossils were linked to specific rock strata.

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.

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.

Identify and briefly describe the major factors which create
four separate and distinct seasons for the people of Indiana .
Answer:
tilting of the earth.
Explanation:
Tilting of the earth is the factor which is responsible for seasons. Those areas which receives direct sunlight have hot climate such as areas at and near equator, while those areas which are nearer to the poles have cold climate. During spinning of earth, it tilted which causes seasons. There are certain planets which has no tilting so there is no season on that planet while our earth tilted about 23.5 degree which is the main cause of 4 seasons in different countries like Indiana.
