1. Nathan is given an image showing three rock layers and an intrusion of 10 points basalt. He is asked to determine the order in which these layers were
formed. Nathan already knows that when molten rock pushes its way into
rock layers already formed, it creates an intrusion. A diagram is provided.
Which of the following indicates when the basaltic intrusion must have
occurred?
Key
Sandstone
Limestone
口田園
Granite
Basalt
O After the limestone was deposited
O Before the granite was formed
After the sandstone was deposited
O Before all three layers were formed

it's filtration, but this is an assumption so my apologies if i got this

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
