<p>The hydrological cycle is a closed system because the amount of water in the cycle remains constant, with water neither entering nor leaving the Earth and its atmosphere. The drainage basin cycle is an open system because it has external inputs and outputs, with the amount of water in the system varying over time.</p> Signup and view all the answers

<p>The two main types of mass movement in river valleys are slumping and soil creep.</p> Signup and view all the answers

<p>Slumping in river valleys is caused when the bottom of a valley side slope is cut away by the river flowing at its base, making the slope unstable and causing weathered material to slump down towards the river.</p> Signup and view all the answers

<p>Attrition is the process of particles of material being carried by a river becoming rounder and smaller as they collide with each other.</p> Signup and view all the answers

<p>Deposition is the laying down of material transported by the river. It occurs when there is a decrease in the energy, speed, and discharge of the river.</p> Signup and view all the answers

<p>The long profile of a river changes downstream by becoming wider, deeper, and smoother. Discharge and average velocity also increase downstream, as does the amount of load being transported.</p> Signup and view all the answers
