Winds and ocean currents do not move in straight lines because of the Coriolis Effect.
GPS Satellite Constellation: The baseline satellite constellation consists of 24 satellites positioned in six earth-centered orbital planes withfour operation satellites and a spare satellite slot in each orbital plane. The system can support a constellation of up to thirty satellites in orbit.
Answer:
Physical weathering enhances the rate of chemical weathering .
Explanation:
Physical weathering is the breaking down of rocks by various processes like freezing and thawing without altering the rocks chemical composition.
While, chemical weathering involves the disintegration and dissolution of rocks by the chemical processes like oxidation , carbonation and solution processes etc.
Generally a fractured rock can easily be weathered by chemical agents rather than a normal fractured rock.
So ,
when a rock is already subjected to physical weathering, the rock will develop cracks on it and when the chemical agents comes in contact with that rock, the chemical solution will penetrate into those cracks and will dissolve the rocks at a rapid rate.
Answer:
There are so many different ways that people communicate nowadays that would not have been possible years ago. The amount of people who have started campains for out Earth, for people in need, and for their interest is crazy and unbelievably. Would never have been possible without social media.
Explanation:
Answer:
D) the steady, clocklike decay of certain radioactive isotopes over time.
Explanation:
Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
For example, when rocks are formed, such as igneous rocks (formed when molten rocks cools), certain radioactive atoms are trapped inside the rocks during this formation process. Then these radioactive atoms decay over time.
The age of the rock can be estimated by comparing the occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
From the options;
A) this is about the formation of the radioactive molecules and not about radiometric dating
B) this is radiocarbon dating (cabon dating/carbon-14 dating)
C) the <em>assumption </em>is wrong since the radioactive isotopes decays not accumulate.
D) the corect option as I explained earlier.
