The size of the pebble will decrease down stream because the further downstream you go the quicker the river velocity. This means there will be more abrasion against the sides and bed of the river and the friction will be greater, this wears away the river load making it decrease in size. Increase velocity means that bigger material will be picked up by the river and carried as river load. More load in the river and increased size of load will mean more attrition and the river load will keep colliding into each other smoothening and rounding their shape. Brap brap !!
Channel depth typically increases as you move downstream due to the accumulation of water volume and sediment load from upstream sources. As the flow progresses, the river or stream gains more energy, allowing it to erode deeper into the channel and carry a greater volume of water. Additionally, downstream channels tend to widen, which can also contribute to increased depth.

Air pressure decreases the higher up you go, according to Boyle's law volume and pressire are inversely proportional, so volume will increase.
According to the state equation pv=nrt p=pressure v=volume n=number of moles r=gas constant t=temperature. p and v are inversely proportional; as p increases, v decreases, as v increases, p decreases.
Not necessarily.
To turn down the volume of the notification sound on a Huawei 1850 Ideos, you can go to the Settings menu, then select Sound and Vibration. From there, you can adjust the notification volume slider to decrease the volume of the notification sounds.
It's when you load and go somewhere
When it's cold, the molecules in the mercury slow down and become more compact, leading to a decrease in volume. This reduction in volume results in the mercury level dropping in a thermometer.

Velocity increases in a downstream direction because more sources of water combine depth and width. A constant flow of water would result in a higher river velocity.
The water is running faster and has eroded the bank.
