Answer:
alluvial fan
Explanation:
Alluvial fans are a mix of sediments made up of mostly sand and gravel that are created when canyons, hills or mountains interact with flowing water. They help with the sustenance of life and irrigation farming as the main source of water.
Answer:
There are 37 time zones in place today
Answer:
Two stars (a and b) can have the same luminosity, but different surface area and temperature if the following condition is met:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
Explanation:
The luminosity of a star is the total energy that produces in one second. It depends on the size of the star and its surface temperature.
L = σ(T^4)(4πR^2)
L is the luminosity f the star, T is the temperature of the surface of the star and R is its radius.
Two stars can have the same luminosity if the relation between the radius and the surface temperature is maintained.
To see this lets suposed you have 2 stars, a and b, and the luminosities of each one of them:
L_a = σ(T_a^4)(4πR_a^2)
L_b = σ(T_b^4)(4πR_b^2)
you can assume that L_a and L_b are equal:
σ(T_a^4)(4πR_a^2) = σ(T_b^4)(4πR_b^2)
Now, you can cancel the constants:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
as long as this relation between a and b is true, then the luminosity can be the same.
Answer is b
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
#1 is a natural process of the minerals and things in rock is not destroyed but rather moved.
#2 weathering breaks down the material while erosion just moves it.
#3 <em><u>gully,rill, and sheet</u></em>
#4 climatic characteristics( rainfall,wind and atmosphere"temp")
#5 they are effected bye temp ans perspiration(rain) there will be more flooding for a mid temp and rainy area while a dry and hot area will have more rocky areas
#6 wet areas will erode away and have less land to use and the dry areas will have nutrient low sand and more rocks then actual dirt
#7 it makes the soil loose the nutrient s and casue tons fo farmland to loose a good quality of use.
#8 farm land wont produce as much cause there is nothing to fuel the plant growth.
#9 farmers and humans will need to move around more and tear down more natural land to find suitable soil or else there will be famine all over
#10 since farmers have to till massive amounts of tops soil in order to be able to use the land it cause erosion from the wind rain etc. causing land to fail cause mudslides etc. then famine start setting in cause there would be now more suitable land for farming cause farmers would move around and use up all the land.
i hope these are right if one is wrong then put in comments
