What is the significance of the boundary between the cretaceous-tertiary time periods?
This boundary, called the K-T, or Cretaceous(K)-Tertiary(T) boundary, is around 65 million years ago and marks the point which dinosaurs are no longer found in the rock record.
What biological findings have been reported at the K-T boundary?
Malay ko
Is it true that charged particles from the solar wind come closest to earth at the equator where earths magnetic field lines dip to earths surface?
t
What caused the K-T boundary?
The impact of a meteorite about 65 million years ago that caused mass extinction on Earth.
Where are the oldest rocks in the atlantic ocean found?
well none of the ocean crust is more than 175 million years old because subduction happens. subduction is when an ocean plate moves slowly into a continent plate and then goes under it and get devoured by the mantle because its lighter than the continental crust. so the answer to your question would be around the edges of the pacific plate.
What is found in the K-T boundary?
I think you are referring to the 'iridium spike' - the Yucatan impactor brought to earth a quantity of iridium that was deposited and is detectable at the K-T boundary (the Cretaceous - Tertiary boundary) wherever this is found round the planet.

What does protruding?
I t means Extending out above or beyond a surface or boundary
What is T in the equation G equals H TS?
The temperature in kelvins at which the reaction is happening

How much uranium do you have in the earth?
An estimation is 50.106 t in the earth crust and oceans.
When this happens, crust bends downward and sinks under the other because it is?
t
What is letters that stand for the organization that conducts research into problems of flight within and bryond earths atmosphere?
it is t t is the letters
How do you scientist know that K-t extinction took place?
1. There is an unusually high concentration of Iridium found at the K-T boundary. Iridium loves to stick to Iron, so the Iridium that would have been on Earth originally is in the Iron core, not in the crust. Therefore, the Iridium must have been introduced by an external source; a meteorite. 2. Shocked Quartz is found at the K-T Boundary all around North America. Shocked Quartz is only produced naturally by bolide impact. Since the K-T meteorite impacted in the Mexican peninsula, it makes sense that the shocked quartz would be found only in relatively close proximity to the impact site. 3. Microtektites, which are normally found at meteorite impact sites, are found at all K-T boundary impact sites. 4. There is a massive impact crater in the Mexican peninsula. 5. In many of the K-T Boundary sections there is a fine layer of ash (disseminated Carbon) from the global wildfires that were caused. 6. There was a fern spike because other flowering plants stopped producing pollen for awhile. 7. Microdiamonds have been detected at K-T Boundary sites, but not above or below.
How does this principle makes it easier for geologists to understand earths?
I don' t know
What is the K-T boundary?
The KT Boundary (also called the Cretaceous-Paleogene, or K-Pg boundary) is a boundary marking the Cretaceous-Tertiary extinction (KT extinction) event. It is usually seen as a thin band, caused by an asteroid impact that wiped out much of life at the time.
