Answer:
explained below.
Explanation:
b) Urbanization decreases the lag time because the loss of the rainfall decrease as the water absorbed by the ground decreases and water reaches to the river very quickly.
c) In urbanization the runoff occurs for small period of time because there is no hindrance in the flow of the rainfall so the runoff reaches very quickly to the water body.
d) Intense rainfall in urban area often experience the flash flood condition because there no absorption of water by the ground, trees are less so which does not lead to perception of water by leaves of the tree hence all the rainfall is basically converted into runoff and city does not have system to act on the situation which lead to flash flood condition.

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:
The key geographic questions ask Where is it located? Why is it there? What is the significance of the location? As students pose additional questions, they seek responses that help to organize spatial understandings: What is this place like?
