Answer:
a. Increases tremendously in luminosity
Explanation:
- The helium flash is a thermal nuclear fusion with large quantities of helium gas into carbon. During the red giant phase, the sun is predicted to have a flash 1.2 billion after it leaves the main sequence and this helium fusion cannot be produced by the low mass stars.
- The sun in this stage will burn out or run out of its fuel and eventually will lead to gravitational collapse. The star being to shrink in size and core starts to collapse.
Answer:
Soil salinity is the salt content in the soil. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean.
Explanation:
Answer:
The answer is below
Explanation:
The question is not complete since no map is attached, but I would show you how to solve it.
When trying to determine the location of the epicenter of the earthquake, we need at least three different seismic stations. To find the epicenter, a method known as triangulation is used. This is done by drawing circle at each of the seismic stations with the radius of the circle equal to the distance from the station to the earthquake. The point of intersection of this three circles is the epicenter.
In this problem, a circle with a radius of 380 miles is drawn at Phoenix, 280 miles radius circle at Denver and a 880 miles radius circle at California. The point of intersection of the circle gives the epicenter. Note that the circles are drawn to scale.
It depends on the map. There should be a key indicated.
