K-T stands for Cretaceous-tertiary boundary. The K is used instead of a C to help that there is no confusion between the Cretaceous and Carboniferous Periods; as the Carboniferous Period was among one of the first periods. The K-T boundary is marked by the element named Iridium, the K-T boundary contains approximately 31% iridium, this element is rare on Earth, common in space debris, such as asteroids and meteors/meteorites, such as the one believed to have hit the Earth causing the extinction of the dinosaurs. The Cretaceous was the last of the dinosaur bearing periods. The Tertiary period is the period we as humans live in currently.
What else can I help you with?
What evidence of the KT boundary in Colorado has been discovered by researchers?
Researchers have found evidence of the KT boundary in Colorado, including a layer of sediment containing high levels of iridium, shocked quartz, and microtektites. These materials are characteristic of the impact event that caused the mass extinction of the dinosaurs.
When was Boundary-Layer Meteorology created?
Boundary-Layer Meteorology was created in 1971.
What is is bliss acronym?
Boundary Layer Infrared Suppression System
Which non-dimensional number relates the thermal boundary layer and hydrodynamic boundary layer?
prandlt no.
What percentage of the then existing species went extinct as a result of the KT boundary event?
75 percent of plants, animals and microbes.
The ratio of thermal boundary layer thickness to the concentration boundary layer thickness is?
The ratio of thermal boundary layer thickness to the concentration boundary layer thickness is typically denoted as Prandtl Schmidt number (PrSc). It is defined as the ratio of thermal diffusivity to mass diffusivity of a fluid and represents the relative thicknesses of the thermal and concentration boundary layers in a flow field.

can boundary layer take place for ideal fluids?
Yes, a boundary layer can take place for ideal fluids. A boundary layer is the separation that is associated with strong flow deceleration or strong adverse pressure gradients.

What is a layer in math?
A boundary layer in math is a region of very large values of the gradient of a certain function. It is also stated that a boundary layer has its origin in fluid dynamics.
