The flags that were placed by people who landed there
Answer:
<u>Geocentric Model</u>: - this model is Earth Centered
-Retrograde motion is explained by epicycles
<u>Heliocentric Model</u>: - This model is Sun Centered
-Retrograde motion is explained by the orbital speeds of planets
<u>Both models</u>:- Epicycles and deferents help explain planetary motion
-Planets move in circular orbits and with uniform motion
-The brightness of a planet increases when the planet is closest to Earth
Explanation:
Retrograde motion is an apparent change in the movement of the planet through the sky. Ptolemy's model of the solar systems was geocentric, where the Sun, Moon, planets and start all orbit the Earth in perfectly circular orbits. However this perfectly circular orbits around the Earth did not explain the occasional retrograde motion of the planets. In the Copernicus' heliocentric model, retrograde motion of planets is naturally explained. The explanation for retrograde motion in a heliocentric model is that retrograde occurs roughly when a faster moving planet catches up to and passes a slower moving planet.
Answer:
Explanation:
Atlanta and Dallas both have the Cfa (humid subtropical) climate type, but Atlanta is in the temperate broadleaf and mixed forest biome and Dallas, which is drier and hotter in the summer, is on the eastern edge of the temperature grasslands, savannas, and shrublands biome.
<span>Areas immediately to the leeward of the mountains have a microclimate with sparse precipitation called a rain shadow.
It is described as "</span><span> a patch of land that has been forced to become a </span>desert because<span> mountain ranges blocked all plant-growing, rainy </span><span>weather" On one side of the mountain the weather is wet, rainy and snowy. And on the other side (the rain shadow) there are no precipitations. </span>
Answer:
The true statement is - Sympatric speciation only occurs in areas where there is local variation in environmental resources
Explanation:
- Sympatric speciation means the evolution of new species from an ancestor species which are occupying in the same area and no geographical barrier takes place.
- Overlapping of ranges takes place to the organism and old and new species are living i the same geographical region.
- A dam diving a fish population could lead to allopatric speciation where geographical barrier causes formation of new species which are completely different from their ancestor species.
