Answer: Igneous Rock

Explanation: Radiometric dating is used to date rocks by measuring the decay of their composite materials. Stable isotopes remain the same over   time while the nucleus of an unstable or radioactive isotope will decay to form other isotopes .

Dating rocks using Isotopic methods uses the decay time of the isotope in the rock to assess its age. The accuracy of this method is assured by the fact that when these isotopes decay, they are retained in the rock. Isotopic dating is not very accurate in sedimentary rocks because they contain particles from older rocks.

1. Susan is a space scientist who made this diagram of the Moon and Earth, as seen from above (top view), with sunlight coming f
Sophie [7]

Answer:

d . Because Susan’s diagram is showing that the half of the Moon that is facing the sun is lit by the sun, and the other half is dark

Explanation:

We can see on the diagram on the left side arrows that show the way from which sunlight appears.<u> It only lights up the left side of the sun, while the right one stays dark.</u>

<u>The moon does not produce any light or energy on its own, so only the side that is facing the Sun at the moment is lit up. </u>That is also the only side we can see from the Earth.

Because of the way and pace Earth and moon move through space and around their own axis, we can only constantly see only one side of the moon. The other side always stays dark, and it is often called the “far side of the moon”.

The position of the sun and moon also determine the phases of the moon we see from the Earth. If more of the moon is visible, that means the moon is positioned to directly face the sun and be lit up. If we don’t see much, the sun lights up only that portion of the moon.

Marina CMI [18]

Answer:

Geostrophic wind D) flows parallel to contour lines of upper-air pressure .

Explanation:

Geostrophic wind -

Air parcel generally moves from higher pressure to lower pressure due to pressure gradient force and left or right deflection due to coriolis force. When this deflection takes place a time comes when pressure gradient force and coriolis force becomes equal and the air parcel moves parallel to isobar then the winds are called geostrophic winds .
