Answer:
llllllllllllllllllllllllllllllllllll
Answer:
Check the explanation
Explanation:
1) Vector sampling refers to the process of sampling locations at intervals along the length of linear entities like roads, or around the area entities perimeters just like property parcels.
So the correct answer is option 2 i.e vector.
2) Raster sampling involves sampling attributes and features at a fixed interval and is generally used to measure the slope of an area.
So the correct answer is option 1 i.e 'raster'.
-70+40 is like subtracting 70 and 40, but adding a negative sign in front. The answer is -30
Answer: a circle and uniform motion
Explanation:
Ptolemy's model of the universe placed the Earth motionless in the center of a universe subject to uniform circular motion, the other planets, the Moon and the Sun describe complicated orbits around it.
As Ptolemy was a respected astronomer and geographer, this idea was accepted for a long time, until Copernicus arrived with the new model (heliocentric theory) that placed the Sun at the center wir the Earth and other planets describing circular orbits around the star. However, <u>the heliocentric theory did not explain why planets orbit the Sun at different speeds at different times, because this model used only circular orbits in uniform motion. </u>
All of this is due to the Greek ideologies of perfect form and motion with a perfect circle. But then, the astronomer Johannes Kepler refined the Copernicus' heliocentric theory with the introduction of <u>elliptical orbits.</u>
B: becomes foggy or rainy because cool air holds less water vapor.
Explanation:
The maritime tropical air masses are warm and humid, while the air masses forming over the land tend to be dry, in some parts are cold and in some parts hot. When these two collide, the weather rapidly changes. If the maritime tropical air masses moves toward the colder ground surface, then the weather will become foggy or rainy.
The reason for this is that the water vapor in the maritime tropical air mass will start to condensate because of the lower temperatures, so precipitation will form. The precipitation is usually manifested through rainfall, while in the mornings it tends to be foggy.
