Answer:
The direction of rivers are usually expressed with respect to the directions we are familiar with: North, South, East or West.
A river has an origin, usually at a higher latitude and ends at the sea or ocean or a large water body. Gravity is the driving force for river flow. Hence, we gauge the ‘direction’ the water is going to flow for any river.
If we were going to get more technical, flow in rivers and streams are measured for their streamflow, which is the amount of water passing through some infinitesmal volume, i.e a point over time. The velocity of the water is determined using acoustic/Doppler based instruments, which will give the local direction of the flow of the river at the measured point along with the velocity.
Hope the answer helps!
Answer:
a. hail
c. tornadoes
d. lightning
Explanation:
It is described as a cloud that is masked and dense, with considerable vertical development, in the form of a mountain or huge towers. Part, at least of its top is normally smooth, fibrous or striated, and almost always crushed; This part often extends in the form of an anvil or a vast plume. Below the base, very dark, low clouds appear torn and rainfall or showers.
They are composed of water droplets and ice crystals on top or anvil. In their interior they also contain large raindrops, snowflakes, granulated ice, hail and in cases of extreme instability of large size.
They almost always produce a storm, that is to say, precipitation in the form of showers, of rain or hail, generally, although also of snow in winter, accompanied by gusty winds and electric discharges that occur between clouds or between cloud and earth (lightning) and even tornadoes
Because of oceans, mountains, and trenches, the earth is not as round.
