<u>From the given options which may suitably apply to the description of grid-lines of the map are
</u>
- They are measured in degrees
- They set up a reference system
- They divide Earth into four equal parts
Answers: Options A, B and E
<u>Explanation:
</u>
Option A describes that the grid-lines of the map are measure in degrees, which are very true as the grid are lined with angular measurement which thus be done in unit of angles and is in degrees only.
Option B says it develops the reference system which specifies about the area being plotted are grid depending upon the size which sets up the referential system of enumeration.
Option E is true as the world or the Earth has been divided into 4 equal parts through the Prime Meridian as the longitudinal line and Equator as the latitudinal line.
Oceanic ridges are volcanic landforms at divergent ocean plate boundaries.
In geology, the Radioactive dating is significant because its provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.
<h3>What is a Radioactive dating?</h3>
This refers to the technique that is used to know the date of materials such as rocks or carbon in which the trace radioactive impurities were selectively incorporated when they were formed.
It determines the dating of rocks and minerals through the use of a radioactive isotopes, it is also useful for igneous and metamorphic rocks that cannot be dated by the stratigraphic correlation method.
As the carbon dating helps to determine the age of an object containing organic material by using the properties of its radiocarbon, it is considered a poor tool for finding the age of the dinosaur skull in the purple layer because the collagen in the dinosaur's bone has usually long since decayed away and is therefore unavailable for radiocarbon dating.

Answer:
50-100 minutes
Explanation:
The process begins again. In some small geysers, the eruption process can take just a few minutes. In larger geysers, it can take days. The most famous geyser in the United States, Yellowstone National Park's Old Faithful, erupts about every 50-100 minutes.
