Why is a drainage basin considered an open system? en-us 2021-01-11 10:42:11 UTC 2021-01-12 04:09:47 UTC hello@padlet.com https://padlet.com/list4/a7ut1pr7aagq5jp8/wish/1076965242 2021-01-12 04:03:59 UTC https://padlet.com/list4/a7ut1pr7aagq5jp8/wish/1076965242 https://padlet.com/list4/a7ut1pr7aagq5jp8/wish/1076965562 A drainage basin is an area of the land surface from which a river receives its supply of water. The drainage basin can be described as a system, consisting of inputs eg. precipitation, stores eg. aquifers  and outputs eg. EVT.  The drainage basin can also be considered to be an open system because it allows the movement of energy and matter across its boundaries. ]]> 2021-01-12 04:04:13 UTC https://padlet.com/list4/a7ut1pr7aagq5jp8/wish/1076965562 https://padlet.com/list4/a7ut1pr7aagq5jp8/wish/1076965636 key features of a drainage basin are
1. Source- start of the river, mainly in the mountains
2. river channel
3. Tributaries- small rivers that flow in larger rivers
4. confluence- when two rivers meet
5. watershed-  dividing lines between two tributaries
6. mouth- where the river leads into the ocean or lake/ end of the river]]> 2021-01-12 04:04:17 UTC https://padlet.com/list4/a7ut1pr7aagq5jp8/wish/1076965636 https://padlet.com/list4/a7ut1pr7aagq5jp8/wish/1076966065 The key features of a drainage basin are 
-main channel/river
-tributary
-mouth 
-watershed
A drainage basin is considered an open system because it allows matter and movement of energy through its boundaries

It also allows movement of energy and matter across it's boundaries. Example of an input is precipitation such as rain fall or snow. Output is like the final release of water - river flowing into the the sea - mouth.]]> 2021-01-12 04:04:35 UTC https://padlet.com/list4/a7ut1pr7aagq5jp8/wish/1076966250 https://padlet.com/list4/a7ut1pr7aagq5jp8/wish/1076966319 A drainage basin is an open system because it is open to inputs from outside (eg. precipitation) and is responsible for outputs out of the system (eg. into the sea)

- It is the area around a large river which contains all of its tributaries.
- open system
- Points of confluence

-  tributaries  are small streams within the drainage basin

- River (Main channel)
- Source of river
- Tributaries
- Mouth of river (could end at lake or sea)
- Confluence

The main characteristics are: river channel,  water shed (imaginary boundary), confluence (join of smaller and larger river joining), tributary...
A drainage basin is considered an open system because there is the factor of water loss through evaporation and water falling onto another drainage basin.]]> 2021-01-12 04:05:02 UTC https://padlet.com/list4/a7ut1pr7aagq5jp8/wish/1076966920 https://padlet.com/list4/a7ut1pr7aagq5jp8/wish/1076967971 -  a drainage basin is an area where rain and other sources of water collect and drain into a larger form of water
