How does water affects Earth´s features
Deposition
All moving water has energy, and water runnind downhill is the main process.
Deposition is the process of adding sediments to a new place after being carried to another. The shape and direction of a River changes.
Minerals in lakes and Oceans
Rivers carries sediments and minerals to the ocean.
It deposits in lakes, along the coast and ocean floor.
A mineral carry by water is salt.
River systems
Rivers and streams are dinamic systems, so they are always changing.
A stream begins on land that is higher than sea.
As a stream flows, other streams may join it, until a river forms.The flowing river water wears down soil and rock and carries the sediments away.
Wave energy
Oceans waves carry and pass along a great deal of energy.
The water stays in the same spot, rising and falling in a circular motion. As wave aproaches the water moves slightly forward and back in a circular loop. Each time a waves passes, the water ends up just about where it started.
As a waves moves toward shore, the shallower ocean bottom and interfers with the waves movements. The ocean floor can cause the bottom of waves to slow down.The tops of the waves moves quickly, so the tops move forward.
Floodplains
When rivers and streams flood their banks their water often slows down and sediments are deposited.
A flood plain is that part of the landscape that is likely to receive the overflow water and sediment from a flooded river.
In some places farmers depend on flooding because sedimments add to the soil nutrients for growing crops in cases floods are very destructive.
Causes of waves
They can be caused by wind or tectonic activity.
Beaches dinamic systems
Waves also carry sediments that can wear down coastal landforms.
Waves also build beaches by moving sand along the shore.
Wind can also change landforms along the coast.
Coastal landforms are constantly changing as water and wind act on them.
Not all beaches are the same.
Wave characteristics
Scientists use certain characteristics to describe all waves.
The highest part of the wave is the crest and the lowest is the trough. The Wavelenght is the distance from the crest to the trough.
If you mesaure the line of the crest or the trough you know´s the wave amplitude.
