The Water Cycle Flashcards
What are the 14 parts of water systems
Oceans
Bays
Coral reefs
Beaches
Rivers
Tributaries
Lakes
Ponds
Wetlands
Riparians
Glaciers
Icebergs
Ground water
Waterfalls
Oceans
Large saltwater basins covering 70% of earths surface. Although it is all connected, we divide it into five separate oceans: Arctic, Atlantic, Indian, Antarctic, and the biggest one, pacific.
Bays
Bodies of water partially surrounded by land. Can be fresh or salt water.
Coral reefs
Comprised of polyps or corals. These living organisms are part of the invertebrate family. Occur in tropical or subtropical waters close to the equator. The largest is called the Great Barrier Reef in Australia.
Beaches
Portions of land where water meets inland areas. Characterized by sand and small pebbles caused by erosion. Located beside oceans, lakes, and rivers.
Rivers
Channels of water that flow or drain into a larger body of water (lake, ocean, or larger rivers). Can be wide and deep or shallow enough to walk through. Flow of rivers may change seasonally. Smaller channels are called creeks, streams, or brooks. Most rivers contain fresh water. Rivers that meet with oceans are called estuaries. These can be half salt and half fresh water. Can carry nutrients through.
Tributaries
Smaller streams that feed into one larger one. The larger river is called a mainstream.
Lakes
Slow moving bodies of water that gather in the depression on the land. Usually fresh water but saline lakes have high salt content like the Dead Sea in Israel.
Ponds
Smaller bodies of water that gather in land depressions. Can be naturally occurring or man made.
Wetlands
Areas of land saturated with water. Essential to ecosystems because they filter out excess minerals, sediments, and pollutants before reaching other bodies of water that animals drink from. They provide homes to many kinds of wildlife and allow plants to thrive inside them. They also are able to slow the flow of water during floods
Riparian
Zones between the shoreline of a water source and the lush vegetation beside it. Home to many species and known as the ribbon of life. It is essential to keep these zones natural to support the species living there.
Glaciers
Compacted snow, ice, sediment, and rock that gather in mountainous regions. Polar regions are known for these large structures of slow-moving ice. Glaciers contain the most accessible water for us to drink and hold 2% of the entire worlds water.
Icebergs
Pieces of broken off glaciers. Found in the sea but are made of fresh water. Glaciers and icebergs formed during the ice age over 10 000 years ago.
Groundwater
Found under the earth. Water travels down through cracks in stone and soil, known as aquifers. Water drains and fills the empty spaces through these aquifers until it reaches an impenetrable layer of rock. The open areas that fill with water are saturated zones, and the top is called the water table. Groundwater can travel to rivers, lakes, oceans, and manufactured wells.
Waterfalls
Waterfalls are unique water features where water flows over a steep incline and plunges to a pool underneath.
Examples of solid water
Glaciers, icebergs, snow, ice.
Examples of liquid water
Precipitation, lakes, rivers, oceans, etc.
Examples of gas water
Fog, clouds, most, steam

The water cycle
Water evaporates from the energy of the sun and turns into a cloud in the sky. Once the clouds get too heavy and filled with water, they precipitate down back to earth. This water can runoff into larger bodies of water again or infiltrate into the ground and percolate further into groundwater. This groundwater can stay underground forever or go back to another body of water through the ground. The water can also go into trees and be transpired up through the trees and back into the clouds and end up in any of these places again.
Watersheds - Basics
Drainage basins
Water sources from higher up places can all drain back into the same central body of water. Can be any size. Everything living in that area is considered part of the watershed as it all has an affect on the water there. Canada has 5 main watersheds: pacific, arctic, Gulf of Mexico, Hudson Bay, and Atlantic. The entire world is technically one big watershed.
Influence on watersheds
Every watershed is unique and will drain differently depending on conditions. The network of the sun drainage systems, vegetation, topography (landforms), and soil types all influence how watersheds drain.
Watersheds - purpose
To slow, filter, clean, and store water. Water quality and health is impacted by watersheds. Water carries harmful pollutants from industries like mining, forestry, and agriculture. This affects our ecosystems. Canada has watershed authorities to help make sure its running correctly.
How can erosion take place?
Water
Wind
Ice
Gravity
Erosion- cut banks
Cut banks are kinda like cliffs on the edge of a river caused by the flow of water.
Erosion - sea stacks
Sea stacks are often vertical stacks found in water that have been eroded away by waves and wind. They tend to be parts of old cliffs that were broken down, then carried away.
Erosion - Barrier Island
These are bigger rocks that have been eroded and surrounded by water.
Erosion - aeolian landform
Basically a sea stack on land. Pieces of old cliffs where the area around it had been weathered and eroded.
Erosion - glacier
Glaciers are ice and move rocks very slowly.
Weathering
Breaks down a rock with physical or chemical change that changes the characteristics of the rock
Erosion
Carried the broken down rocks from weathering away
Deposition
When the rock gets deposited
Heavy rocks go down first which is why there is so many at the shallow end of the lake
Physical weathering
When factors in the environment break down a rock. Ex:
Abrasion is the physical grinding of a rock by waves, wind, water, gravity, plants, or animals.
Frost wedging is the result of water freezing within a rock and expanding, causing a fracture from within.
Thermal stress is when a rock expands and contracts due to temperature changes, which causes fractures.
Chemical weathering
When a chemical reaction occurs, causing a new substance to be created. Ex:
Oxidation is when oxygen combines with iron in the rock, creating iron oxide (rust)
Hydrolysis is when hydrogen replaces the iron in a rock or mineral.
Carbonation is when water and carbon mixes to create carbonic acid. This kind of chemical can dissolve certain types of rock like limestone. Creates caves.
Coastlines are…
A) static and rarely change
B) dynamic and always changing
B)
What common problem do coastlines around the world face?
Erosion - waves carry barriers from the ocean to the people and beach
What events can accelerate erosion beyond normal levels?
Hurricanes
Typhoons
High winds
Why is coastal erosion so important to people near beaches?
Homes are being consumed by big waves and tides coming in. Beaches are a big spot for tourism and if the beaches are gone it can cause huge problems financially.
Solutions to coastal erosion
Seawalls
Groynes
Planting forests
These all take away energy from the waves
Water currents are the ___ of water in the ___.
Flow
Oceans
