The Jurassic is an age that began about 200 million years ago and stretched for about 50 million years to about 150 million years ago. Radiometric dating can identify certain materials as being from that period, but we don't have a "radiometric system" for the Jurassic, per se. Radiometric dating is part of the radiometric (from radioactive measuring) system we use to investigate a number of different things, including the age of materials found on the earth and elsewhere.

In what period did modern musical notation take hold?
Guido d'Arezzo the medieval theorist was the inventor of the modern musical staff. His new system, the one we use today, replaced the older system called the 'neumatic system'. This occured somewhere between 1000 C.E. and 1050 C.E.
The period of history before the invention of writing is called?
The period of history before a viable system of writing had developed was called the Neolithic, or New Stone Age, during the period civilization had greatly developed in agriculture and cities. The first and earliest form of writing involved the symbolic Sumerian cuneiform in Mesopotamia around 3500 BC, which occurred after the Neolithic time period of world history.
What function does the wheel cylinder perform in the brake system?
The wheel cylinder (used in drum brake applications) applies pressure delivered from the master cylinder via brake fluidto the brake shoes to pushagainst the brake drum to stop rotation.
Which system controls heart rate and blood pressure?
The third apsect of the cardiac cycle is the rest period, however it is not separate from the sytole and diastole. It is merely the time frame during a cycle when both the artia and ventricles are in disastole at the same time. It thus can be said that the period of rest overlaps atrial and ventricular diastole.
What are some science words that begin with the letter J?
There are quite a few words used in science starting with the letter J. They include: 1. Joule -- a unit of electrical/mechanical/heat energy 2. Just In Time -- a methodology whereby execution of an operation is delayed or left until the moment it is required. Commonly used in computer science/management science 3.

When did Jurassic Park - Super Nintendo Entertainment System video game - happen?
Jurassic Park - Super Nintendo Entertainment System video game - happened in 1993.
Why can't radiometric dating be used with accuracy on metamorphic rocks?
An accurate radiometric date can be obtained only if the mineral remained a closed system during the entire period since its formation this is why radiometric dating can't be used with accuracy.
What organs apply applies pressure to the circulatory system?
The heart is the organ that applies pressure to the circulatory system.

What is roughly 4.600 million years old?
The age of approximately 4.6 billion years refers to the estimated time of the formation of the Earth and the rest of the solar system. This estimate is based on radiometric dating of the oldest meteorites and lunar samples, which provide insights into the early solar system's development. The Earth formed from the solar nebula, a cloud of gas and dust, during this period.
What sentence would use Geologic Timescale?
The Geologic Timescale is a system of chronological dating that organizes Earth's history into distinct periods marked by significant events or developments, such as the Jurassic Period or the Paleozoic Era.

What is the approximate age of the solar system'?
The solar system is estimated to be about 4.6 billion years old. This age is determined by radiometric dating of rocks from the Earth and Moon, as well as meteorites.
What is the use of a metal lead relating it with uranium?
The system uranium-lead is very important for radiometric dating of rocks (ages between 106 and 5.109 years).
