Answer:
3.29ft/mi
Explanation:
The gradient of a river is the slope through which a river flows. It measures the vertical drop in elevation of river to the horizontal distance.
Mathematically;
River gradient = 
Elevation = 1229ft
Horizontal distance = 373miles
River gradient = 
= 3.29ft/mi
The correct answer is D. Air moving along lines of constant longitude
Explanation:
In geography, the word meridian refers to an imaginary line that connects the North pole and the South pole, this includes the main meridian called Prime Meridian as well as multiple longitude lines that determine East and West.
On the other hand, the meridional circulation refers to a natural phenomenon in which air and air masses move from North to South and vice-versa following longitude lines or the imaginary lines that divide the planet vertically. Additionally, the meridional circulation affects climate especially in terms of extreme weather. According to this, the meridional circulation means "Air moving along lines of constant longitude".
Answer:
Fast flowing waters .
Explanation:
the coriolis effect causes storms to spend in a counterclockwise direction . Jet Streams are narrow currents of fast-moving air in the upper atmosphere. They are created by the flow of air in the upper atmosphere which gets bent and channelled to the East Coriolis effect
Answer: D) Mexico city is in Central America
Explanation:
Reason being that Mexico is part of the North American region with Canada and the United states. The central american countries are all those that border below mexico between mexico and Colombia. Hoped this helped.
Nitrogen and oxygen are the main constituents of the atmosphere plus water vapour near the surface. Carbon dioxide is present in smaller amounts butgl of course it can have a profound influence on the climate as global warming has shown, Greenhouse gases include water vapour, carbon dioxide, methane and nitrous oxide.
