Answer:
15003.19
Explanation:
The fossil bones age can calculated by using the formula
t = (In ( 12.5 /100) / (-λ)) × half life
where λ = 0.693
t = ((In (12.5 /100) / (-0.693) ) × 5000 = 15003.19 years
the age of the fossil bones is 15003.19
thus the age of the human habitation site 15003.19
These organisms get the food needed to survive by filtering the food from the water with the use of their cells. Some of these organisms feed up with different wastes because that is their food and diet. Others use their sense of smell by detecting their food in order to survive.
From the given choices the true statement is Surface winds blow parallel to isobars.
Answer: Option B
<u>Explanation:</u>
The winds which flow near the isobars, flow in the parallel direction of the isobars. They are not absolutely parallel to each other but are this much parallel that the purpose of the flight planning can be fulfilled with this.
These winds flow in perpendicular position to isobars which are present at that particular surface and they flow in this direction due to the acting of the force of friction in that area. This force of friction can also change the direction and the flow of the wind.
Answer:
Stratovolcanoes
Explanation:
Stratovolcanoes are usually defined as those volcanoes that are characterized by the presence of steep slopes, having a height of about thousands of feet and comprised of alternate layers of ash deposited particles and lava flows. These are very explosive and when it comes in contact with water, it erupts violently. These are also known as composite volcanoes. It produces pyroclastic materials, along with volcanic blocks and ashes with a large amount of toxic gases.
Answer:
The best answer to the question: With the discovery of magnetic reversals, there was evidence that:___, would be: the sea floor could create new continental crust.
Explanation:
The theory of sea floor spreading, which came from the studies of how continents formed, and the general mechanics of geology and geophysics, led scientists, since the 1960´s to understand how continental crust, and new land, is formed from the Earth´s lava mantle and the core. This sea floor spreading has been defined as the process during which, as mid-ocean ridges, which delimit two continental plates, move apart, weakening the crust, magna is able to pour through the ridge and form new crust. In relation with magnetic reversals, it must be said that this new crust that forms as lava pours forth will be magnetically charge at the time of its deposition on the surface, and as it cools down, it will store in it the magnetic charge to which it was exposed in the mantle before it was poured forth. As such, magnetic reversal shows that the earth has changed polarity throughout time, polar reversals, and these reversals have been proven through rock evidence that has been present in the ocean ridges, almost like records of the magnetic event.
