Answer:
in the mantle of the earth
Answer:
Radiometric dating is usually defined as a method that helps in calculating the age of rock depending on the presence of radioactive isotopes and its rate of decay. In order to calculate this, the half-life of the isotope element must be known. This method is commonly used by geologists.
The conditions that are needed to fulfill in order to determine the age of a granitic batholith are as follows-
- The rate at which these materials decay must be a constant
- There should be an exact amount of both the parent as well as the daughter elements.
- Since it is a batholith, so it has formed from the crystallization of magma at a certain depth. So, these granitic rocks must have remained within a closed system, right from the time of its formation.
The various methods of radiometric dating that can be used to date this granitic batholith are-
- Uranium-lead dating- It is an efficient method to date the rocks that are of about 4 to 4.5 billion years.
- Potassium-argon dating- It is also commonly used to date rocks that are about 4 billion years old.
Answer:
This simple online tool makes it easy to calculate the difference in hours and minutes between two given times. To calculate the hours and minutes contained in a time period you need to know its beginning and end. The hours calculator will use the time format depending on your browser locale settings, e.g. US, UK.
After you enter the beginning and the end of the time period you are interested in, you simply click the "Calculate difference" button. Below you will get the difference in both full hours and in minutes. If the first hour you enter is later in the day than the second hour you enter, the time difference is calculated as if the first hour is for today and the second is tomorrow. For example, entering a start time of 6PM and end time of 8AM in the calculator, it will calcualte the difference in hours, minutes, and seconds from 6PM today to 8AM tomorrow (14 hours).
This calculator for the number of hours between two times could be used to find out for how long you have worked in order to fill in time sheets. For example, how many hours are there between 9 and 5:30 pm (or 9:00 and 17:30)? You simply need to enter the two times in any order and click on "Calculate". The result will be 8 hours 30 minutes (8:30 hours or 8.5 hours in decimal) or 510 minutes. There are 8 full hours between these times.

Any other type of government besides democracy has no obligation to help the people. We have a representative government as of today I believe.
Answer: a. algal bloom
Explanation:
The availability of food in the systems can tell the types and numbers of organisms in the systems by checking which types of organisms eat the food available as well as the quantity available to see the number of organisms.
Temperature and dissolved oxygen levels also play a huge part in determining the feasibility of organisms staying in the system. The availability of nutrients goes hand in hand with the availability of food in determining the organisms present.
Algal bloom is not a factor in determining the types and numbers of organisms found in a system because the conditions that caused this bloom might not be suitable for other organisms as well.
