\underline{\:\large{\textit{1) \sf Answer \: :}}}

\leadsto The River has mainly 3 different courses. They are as follows:

\boxed{:\implies\mathfrak\red{Upper \: Course}}

  • The Upper Course has a lot of few unique landforms present there, which are mainly caused by the soil erosion.

  • In the case of Mountainous Course, the river passes through the steep slope of mountain. Due to it's steep slope, water gains a high speed & rush fast towards the downwards.

  • Erosion and Transportation are two main types of activities of a river in the Upper Course.

\boxed{:\implies\mathfrak\blue{Middle \: Course}}

  • The Middle Course is seen when river leaves the holly region & enters into a plain region.

  • Hence, Steep of slope in case of plain region becomes less. Therefore, Water flows at slow speed & cannot transport much more material from it.

  • In this course of journey, river is fed by many small lakes & tributaries. Hence, the volume of river goes on increasing.

\boxed{:\implies\mathfrak\purple{Lower \: Course}}

  • When river reaches its mouth part it is termed as Lower Course.

  • Steep of slope in this region of area is not so steep but current is also very less. Many materials carried out by river while flowing gets deposited.

  • Deposition is the main activity of river in this course.

\underline{\:\large{\textit{2) \sf Answer \: :}}}

\leadsto Following are effects of Ocean Currents:

  • \sf\blue{Cause \: of \: deserts.}

  • \sf\pink{Resulting \: in \: rain.}

  • \sf\red{Destroying \: marine \: life.}

  • \sf\green{Resulting \: in \: deaths.}

Explanation:

An ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences.[1] Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean currents are primarily horizontal water movements.
