The index fossils are fossils that are found in the rock strata of certain geologic period, but they are also fossils that are very common and can be found in numerous places around the globe.
Because they can be found all over the globe, and they are indicative of certain geologic period, the geologists have started to use them as a simple way of determining the age of the rock strata. While this method can not provide the geologists with an accurate year for the formation of the rocks, it is still able to determine the relative age of the rocks. By determining the relative age with such ease by using the index fossils, the geologists are able to immediately make conclusions about the rock strata, have basic information about it, and largely be aware of the processes that formed them and influenced them.
Answer:
True
Explanation:
According to Morvel model of Charles Demets the total displacement rate of Pacific plate in comparison with North American Plate at Wallace Creek is 0.051 m /yr. The slip rate of Wallace Creek towards the North is 3.5m due to major earthquakes. Wallace creek is located in central California.
Answer:
Monsoon is a seasonal change. It brings rain and the strongest wind in the region.
Explanation:
Monsoons determine the climate in India and South Asia. The summer monsoon brings many precipitation, humidity, and heavy rains. This period of monsoons lasts between April and September. Monsoons are especially important for India and Southeast Asia because these countries don’t have irrigation systems. The summer monsoon brings the water that is enough for the whole year. That is how rice and herb tea are growing. In India, monsoon rain is very important so that they could feed their cows and keep them healthy.
Answer:
The Cartesian Coordinate System is used to locate a point in space by giving its relative distance from perpendicular intersecting lines (Encyclopedia.com). René Descartes was the inventor of the Cartesian coordinate system with the help of Pierre de Fermat. Descartes used the letters from the beginning of alphabet (constants were identified by a, b, c and so forth) and the letters at the end of the alphabet (x, y, z) were used for variables. These were expressed on the line as equations. The system itself; first coordinate value (x-coordinate) describes the horizontal axis (x-axis) and the 2nd coordinate value (y-coordinate) locates the point of the vertical axis (y-axis). The coordinating system helps duplicate geometric figures (i.e. triangle has coordinates of A (3,2), B (4,5), and C (-2,4) and with these coordinates, you are able to duplicate another.
