Answer: A, B, and D,
C is incorrect because continental drift takes several centuries to move the tectonic plates witch is not an immediate impact leaving you with A,B, and D.
I would say food but like they take weight too
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

Kindly check explanation
Explanation:
Given the following :
Distance between Ranjan and Gomez house = 9km
Start time = 6'o clock
Time he arrived at Gomes house = 7'o clock
Time used for chatting during this period = 5 minutes
Distance covered in 40minutes = 6km
Time spend for second part of the journey = (60 - (40 + 5))minutes = 15 minutes = 15/60 = 0.25 hoir
Distance covered during second part of journey = 9 - 6 = 3 km
Speed = distance / time
Speed = 3km / 0.25 hr = 12km/hr
Average speed for entire journey :
First part :
Speed = distance / time
Time = 40 minutes = (40/60) = 0.667 hour
Speed = 6km / 0.667 hour = 9km / hr
Average speed :
(First part + second part) / 2
(9km/hr + 12km/hr) / 2 = 21km/hr / 2 = 10.5 km/hr
= 10.5km/hr
<u>Answer:</u>
Mass of leaves in scientific notation = 
<u>Explanation:</u>
Number of leaves released by type of deciduous tree = 7500 leaves on average each fall
Mass of 1 leaf = 1.7 grams = 
Mass of 7500 leaves = 
No trees per acre = 206
Area of forest = 135,000 acre.
Total no of trees in 135,000 acre = 135,000 * 206 = 
trees
Mass of leaves fallen in 135,000 acre = 
Mass of leaves in scientific notation =
