Because of all the earthquakes that have occurred. The seven continents used to be one but over the many years there has been a lot of erosion and earthquakes. The continents are still moving so in a very long time there will be more than seven continents most likely.
Organochlorine pesticides, such as DDT, have been known to have a long residence time in the environment. These compounds are resistant to breaking down and can persist in soil, water, and organisms for many years, causing potential harm to ecosystems and human health.
No the list of the worlds longest rivers: Nile - Egypt Amazon - Brazil Mississippi - U.S
Chile
They are the longest rivers in each continents Africa, North America and South America.
Residence time is the time it takes a particle to complete the cycle. Space time is volume of the reactor over the velocity. If the volume does not change and the velocity remains constant then Residence time = space time, however, if there is a disturbance in the reactor (i.e., change in pressure, temp, ect.), then residence time does not equal to space time.
the hydraulic residence time t is given by t=V/q where V is the volume in the tank and q is the volumetric flow rate. A theoretical residence time can be given by the relationship between concentration and time ln(C)=-(t/tav) where tav in this equation is the residence time.
The Longest Time was created in 1983.
Amazon river (South America) River Nile (Africa)
They are the longest rivers in each continents Africa, North America and South America. Correction: The Missouri River is the longest river in the U.S.
Russia has nine time zones spanning two continents.
