The Mississippian is a geological epoch in Earth's history, recognized by the International Commission on Stratigraphy, and the Early Carboniferous. The Mississippi period dates from about 359 to 318 million years ago.

Like many other geochronological dates, scientists can use the rock beds to identify the Mississippi, although the exact beginning and end times are still uncertain. The Mississippian is named after the Mississippi River in the United States because the Mississippian rock formations are widely distributed here. The Mississippian rock formations of North America contain many marine limestones that are pre-Pennsylvanian and pre-Devonian.

The International Commission on Stratigraphy divides the Mississippian into three orders: the Tournaisian, the Visean, and the Serpukhovian. The European scientific community usually divides the Carboniferous period into the Dinanic and Silesian periods, while the North American scientific community divides the Mississippian period into four phases:

Kinderhook (the time corresponds to two-thirds of the time of the Tournai order). Osai Tier (time equivalent to Tier Tournai, Late Tier to Constitution Tier). Mermeck Tier (time equivalent to the middle of the Constitution Tier).

Chester Order (Late Constitution Order to Serpukhov Order).

Mississippi is a southern state in the United States and the state with the highest percentage of black people in the United States.

The climate in Mississippi is warm and humid, with long summers and short winters. The average temperature in July is 28 degrees Celsius, while the average temperature in January is 9 degrees Celsius. The lowest temperature on record was recorded in 1966 and the highest temperature was recorded in 1930.

In winter, there is a light amount of snow in central and northern Mississippi.

Mississippi River Location: North America.

The Mississippi River originates from the source of the Missouri River, the largest tributary of the eastern Rocky Mountains, and is 6,020 kilometers long, ranking fourth in the world. The basin extends from Lake Aitasca near the Great Lakes in the north, to the Gulf of Mexico in the south, to the Appalachian Mountains in the east, and to the Rocky Mountains in the west, with a basin area of 3.22 million km, accounting for about 1 8 of North America.

The Mississippi River is home to more than 250 tributaries, with more and longer tributaries on the west bank than on the east bank, forming a large asymmetrical dendritic water system. The water volume is abundant, and the average annual flow near the estuary reaches 10,000 cubic meters per second.

The Mississippi River is the largest river in North America, and together with its main tributaries, it is the third largest river in the world in terms of basin area (about 3.1 million km) after the Amazon River in South America and the Congo River in Africa.

The Mississippi River is geographically located in North America.

The Mississippi River is 3,767 km long and is sourced from the Upper Mississippi River, which originates in Lake Aitasca in the northern United States. It is the river with the longest flow, the widest basin area and the largest volume of water in North America, located in south-central North America. The average annual sediment discharge of rivers is 100 million tons.

The basin is one of the three major black soil regions in the world.

Redrock Creek (located in Montana), a tributary of the Missouri River that originates in the Rocky Mountains of the western United States, is usually the source of the river, with a total length of 6021km, ranking fourth among the world's rivers, accounting for 41% of the continental area of the United States, covering a vast area in the east and center, and the average annual sediment transport of the estuary is 100 million tons.

The Mississippi River, located in south-central North America, is the largest river system in North America[5][6], with a basin area of about 3 million square kilometers [7]. It is also the longest river in North America, with its source at Lake Itasca at an altitude of 446 meters in northwestern Minnesota, USA, flowing through the Great Plains and emptiring into the Gulf of Mexico in the south.

Lake Redrock, the source of the Missouri River, the longest tributary, is 3,767 kilometers long [7]. If calculated according to the source of the Missouri River, a tributary of the Mississippi River, the total length is 6,021 km, ranking fourth among the world's rivers.

The western tributaries of the Mississippi River are more numerous and longer than those on the eastern side, forming a large dendritic water system. The water volume is abundant, and the average annual flow near the estuary is 10,000 cubic meters per second.

It is about 1,010 kilometers long from its source Lake Eitaska to Minneapolis and St. Paul. The terrain is low and flat, the water flow is slow, and the glaciers, lakes and swamps on both sides of the river are dotted, and the lake water often forms rapids and waterfalls, and then flows into the main stream. Near Minneapolis, it flows through a kilometer-long canyon rapids with a drop of meters, forming St. Anthony's Falls (drop meter).

Minneapolis and St. Paul to Cairo at the mouth of the Ohio River are the middle reaches, with a length of about 1,373 kilometers. The section of the river north of St. Louis has a steep riverbed, with cliffs and rapids on both sides. The valley near St. Louis is carried out, 10 to 15 km wide.

South of St. Louis, the riverbed ratio decreases, and from Cape Girardo below, the curvature of the river increases significantly, and the valley gradually widens, reaching a kilometer wide at the confluence of the Ohio River.

Below Cairo is the downstream, which is about 1,567 kilometers long. It flows through the plain area, and the width of the river is generally 730 1370 meters, the specific drop is small, the water flow is slow, and there are many meanders, oxbow lakes and sandbanks, and it has the characteristics of an old river.

In the upper reaches, the spring snowmelt and rain supply are the highest in April, the second highest water level in June, and the low water level in December. The midstream Missouri River flowed to 5,800 cubic meters per second, with the highest water level in June. The lower Ohio River provides 57 percent of the main stream, with a flow increasing to 10,000 cubic meters per second, with the highest level in April and the lowest level in October.
