ocean
what do ocean currents do?
ocean currents move warm water and cold water around they go all around the world.
how do rivers affect the land?
rivers shape land as they flow over it
NAME THE DEFINITION
Levee
a raised bank on the edge of a river channel.
what is a Meanders
Meanders form on slow-moving rivers with very little slope
where are most cool currents going to?
antarctica and alaska
how do rivers affect habitat
Rivers are ecosystems that provide homes for many species. These animals can live around the water or in the water.
NAME THE DEFINITION.
the process by which weathered material is laid down or deposited by wind, water, and ice.
deposition
what are characteristics of a river
They change the shape of the land and affect the habitats of living things
where are most warm currents going?
North America, Africa, Australia, Europe and Asia.
what can rivers create?
they form different landforms such as valleys and deltas
NAME THE DEFINITION
the shallow gently sloping submerged zone of a continent next to an ocean
Continental Shelf
do rivers become inter connected?
yes. Rivers become interconnected channels as it flows around them creating a braided pattern
do ocean floors change when plates shift?
yes. Oceans floors actually change so as Earth's plates shift, they cause the ocean floor to spread out. When Earth’s plates slide, the ocean floor gets smaller.
how do rivers shape the land
Rivers shape land as they flow over it. When they flow over land, rivers form different landforms such as valleys and deltas. When the water rises and forms a delta it floods the land. That's why in this photo it has these water streams everywhere.
NAME THE DEFINITION
El Nino
a mass of warm water that travels from the western to eastern Pacific
what are some parts of a river
Watershed- the line of high ground that separates water from flowing in one direction from another
Drainage basin- the area drained by a river system
Source- where a river or stream begins, for example, a spring or a glacier high on the mountains
Tributary- a stream or river that flows into a larger one
Channel- the depression where water flows; the path a river takes
Floodplain- flat, low-lying area near a river or stream that may be regularly flooded
Meander- loop or bend in a river
Riverbank- the land on the sides of the river
River bed - the bottom of a river
Delta- a plain formed by a deposit of sediment where a river enters a lake or ocean, typically a triangular shape
Mouth- the part of the river where it flows into a larger body of water
how do oceans change the land?
oceans change the land by flooding, shifting of plates, ocean currents.
what can rivers do when they meet with the ocean.
River water can mix with the ocean's salt water. It stirs up sediment. Sediments are the little pieces of matter at the bottom of leftover liquids. This provides plants with nutrients and minerals to help them grow.
NAME THE DEFINITIONS
a simple plant ranging from one-celled forms to seaweed and giant kelp
Algae
what are some river patterns
The change depends on the type and slope its moving through
Rivers flow quickly and straighter when they’re on a steeper slope; Rivers flow slower when they are on gentler slopes
Rivers erode and deposit materials in other places
The shape of a river changes and may form meanders or braided patterns
