Answer:
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).
Explanation:
A shows the physical features of the land
Explanation:
A topographic map is a map that shows the physical features of the land area. Rivers, streams, mountains, valleys, hills and other physical features.
- A topographic map is made up of series of contour lines.
- The contour lines are lines that joins places of equal elevation.
- All places on the contour lines have the same elevation.
- Using the contour lines, we can understand the landforms in an area.
- Other map keys are used to delineate settlement patterns, streams, churches, dams and the like.
- Most topographic maps are used as base maps for making other maps.

Answer:
oxidation state of sulphur=x
Explanation:
Na2S4O6=2[+1]+4x+6[-2]=0
+2+4x-12=0
4x-10=0
4x=10
x=10/4=2.5
Answer: The volume occupied by 2.50 moles of 
gas at STP is 56.0L
Explanation:
According to ideal gas equation:
P = pressure of gas = 1 atm (at STP)
V = Volume of gas = ?
n = number of moles = 2.50
R = gas constant =
T =temperature =
(at STP)
Thus the volume occupied by 2.50 moles of gas at STP is 56.0L
I'd say it's single replacement/displacement
