This is a powerpoint I share with my students at the beginning of the school year. I like to get them familiar with landforms before we begin Social Studies content.
The majority of water on Earth is salt water, with 97% found in oceans and seas. Freshwater makes up the remaining 3% and is found as ice (79%), groundwater (20%), and surface water (1%). Water quality refers to the amount of substances other than water found in a sample, describing how pure the water is. Potable water is safe for humans to drink. The most common substance in water samples besides H2O is salt. Water quality is negatively impacted by human pollution but also benefited by filtration. Monitoring helps identify quality changes early.
Freshwater ecology is the specialized study of the interrelationships between freshwater organisms and their natural and cultural environments. It examines freshwater habitats like upland rivers and streams, which are fast flowing rivers and streams that drain mountainous areas onto plains. Upland rivers are characterized by rapid drops in altitude, fast water flow, high stream power, incised courses, beds dominated by bedrock and coarse sediments, and a riffle and pool structure.
The document discusses different types of bodies of water such as streams, rivers, lakes, and waterfalls. Streams are small and narrow bodies of water that join together to form wider rivers. Rivers can empty into lakes and range from clear to muddy. People and animals rely on streams and rivers as a source of fresh drinking water.
The earth is made up of water, land, and an atmosphere. Water exists in three states - solid, liquid, and gas. It is the most abundant component on earth and is essential for most living things. Water can be found in oceans, seas, rivers, lakes, clouds, underground, and as water vapor in the air as part of the continuous water cycle.
The document discusses the major forms of water on Earth. It describes the five oceans which cover 70.8% of the planet's surface: Pacific, Atlantic, Indian, Antarctic, and Arctic. It also discusses seas, which are large bodies of water almost completely surrounded by land like the Mediterranean. Other forms discussed include lakes, rivers, gulfs, bays, straits, canals, and the world's longest rivers. The document provides locations and other key details about major examples of each water form.
This document defines various geographic and hydrologic terms. It describes different types of bodies of water like oceans, seas, gulfs, straits, rivers, streams, lakes, and reservoirs. It also defines landforms such as continents, islands, peninsulas, mountains, hills, valleys, plains, and deserts. Additionally, it explains geographic coordinate systems and important lines like the equator, prime meridian, latitude and longitude.
Oceans, rivers, and lakes are the three main types of bodies of water on Earth. Oceans are large bodies of salt water surrounding continents, with the Pacific being the largest. Rivers are flowing bodies of fresh water that cross land and empty into seas or oceans. Lakes are large bodies of fresh water surrounded by land on all sides, such as Lake Kaweah in Tulare County.

The document discusses the five main oceans of the world - the Pacific, Atlantic, Indian, Southern, and Arctic oceans. It provides data on the size and depths of each ocean, with the Pacific being the largest and the Mariana Trench in the Pacific being the deepest location at over 36,000 feet deep. Rivers are described as large bodies of fresh water that flow across land into seas or oceans, while lakes are bodies of fresh water surrounded by land.
The document describes the hydrologic cycle (water cycle) where water is constantly being cycled through the atmosphere, ocean, and land, driven by energy from the sun. Water evaporates from bodies of water and soil into the atmosphere, condenses to form clouds, and falls back to earth as precipitation. Precipitation replenishes groundwater, surface water in streams and rivers, and water in oceans, completing the cycle which is crucial for life on Earth.
Lakes are inland bodies of water formed in depressions where water collects. They are formed through processes like diastrophism, glacial action, and volcanic activity. Lakes provide many benefits like transportation, water storage, hydroelectric power, and recreation. Specific types of lakes include kettle lakes formed in depressions left by melting glaciers, tarn lakes in mountain hollows, and volcanic lakes that form in volcanic craters. Oxbow lakes form from river meanders that are cut off. Swamps occur in low-lying areas and transition between lakes and dry land depending on the season. Rivers are natural freshwater streams that flow towards seas, lakes or other rivers. Meltwater from glaciers feeds streams
The document discusses different bodies of water on Earth. It states that about three-quarters of the Earth's surface is covered by water, but only around 1 cup out of a gallon jug representing all the world's water is freshwater. Most of the Earth's water is contained in the oceans, including the Pacific, Atlantic, Indian, Arctic, and Southern oceans. While oceans contain saltwater, lakes, rivers, ponds and streams hold freshwater that can be consumed. The Great Lakes including Lakes Huron, Ontario, Michigan, Erie and Superior are examples of large freshwater lakes.
The document discusses Earth's water resources and the hydrologic cycle. It explains that 97% of Earth's water is saltwater found in oceans, while the remaining 3% is freshwater. Freshwater is found in glaciers, ice sheets, lakes, rivers, streams, groundwater, and the atmosphere. The hydrologic cycle involves water evaporating from oceans and other surfaces, condensing in the atmosphere, and falling as precipitation before collecting in streams, rivers and groundwater that flow back into oceans, completing the cycle. Human activities like population growth, urbanization, agriculture and industry can negatively impact water quality through pollution and overuse.
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. Water can change between liquid, solid, and gas states in this cycle. In its purest form, water is a chemical compound made up of two hydrogen atoms and one oxygen atom. Bodies of flowing water include rivers, creeks, brooks, and canals, which vary in size and flow. Bodies of non-flowing water include oceans, lakes, ponds, reservoirs, sloughs, marshes, and estuaries, and also vary in size and salinity.

This document summarizes various bodies of water and landforms. It describes the four main oceans, how ocean currents affect climate, and details about lakes, rivers and streams. It also explains the hydrologic cycle of water evaporating and condensing, drainage basins, water tables, and various landforms like continental shelves that can be found on land and in the ocean.
This document summarizes the major water bodies of Earth. It explains that 3/4 of the Earth's surface is covered by water in various forms called water bodies. The largest water bodies are the five oceans: Pacific, Atlantic, Indian, Arctic, and Antarctic oceans. It also describes seas as large water bodies smaller than oceans, which can be marginal seas partly enclosed by land or inland seas covering central land areas. Minor water bodies include bays, lakes, gulfs, lagoons, straits, and rivers.

Rivers form through the natural process of water runoff from land surfaces collecting in low areas and eroding channels over time. As runoff from multiple slopes combines, it increases the water's eroding power to form gullies that eventually develop into full valleys containing a permanent stream, along with tributaries that feed into the growing river system within the watershed.
The document discusses the hydrosphere, specifically water on Earth. It covers the basics of water molecules, the water cycle, oceans, and other bodies of water. The key points are:
- Water (H2O) covers 70% of Earth's surface and is made up of two hydrogen atoms and one oxygen atom.
- The water cycle constantly moves water around Earth through processes like evaporation and precipitation.
- The oceans are the largest part of Earth's hydrosphere, covering over 70% of the planet. The four major oceans are the Pacific, Atlantic, Indian, and Arctic oceans.
- Other bodies of water include lakes, rivers, ice caps, and groundwater, which
There are two main types of bodies of water: flowing and non-flowing. Rivers are a type of flowing body of water that carries water from higher elevations to oceans, lakes, or other rivers. There are different patterns that river channels can take, such as dendritic where many small streams join into larger tributaries, or trellis where tributaries join the main river at 90 degree angles. Seas can be formed through marine transgression when sea levels rise and flood land, marine regression when sea levels fall and expose seafloor, or marine ingression when the sea pushes farther inland.
The document summarizes key aspects of physical oceanography. It discusses the composition of seawater, properties like salinity, temperature, pressure and density. It also describes major ocean basins, currents that circulate water globally, and ocean motions including waves and tides. Overall, the document provides a broad overview of physical characteristics and processes within Earth's oceans.
The document defines and describes various bodies of water. It discusses seas as large expanses of salt water connected to oceans. Rivers are described as freshwater flows towards larger bodies of water. Ponds are smaller than lakes and hold standing fresh or salt water. Streams have currents confined within banks. Oceans are large bodies of saline water forming the hydrosphere. Puddles are small accumulations of liquid, usually water, on surfaces.
Multiple surveys in the Upper Cuyahoga River found healthy mussel populations, particularly in the main stem and West branch, though abundance was lacking in the East branch. The most recent 2015 survey examined the Middle Cuyahoga River, a poorly understood area. The river ecosystem has experienced changes from dam removals and the presence of invasive mussel species, which compete with native Unionid mussels for resources.
The document discusses the hydrosphere and water cycle on Earth. It describes how water circulates between the oceans, atmosphere, and land via evaporation, condensation, and precipitation in the water cycle. It provides details on the distribution of water on Earth, including that 97.5% is salt water in oceans and seas while the remaining 2.5% is fresh water in ice caps, glaciers, inland water, and groundwater. Rivers, lakes, and oceans are described along with their characteristics and locations.
The document discusses key features and processes related to river systems, including the drainage basin, tributaries, confluence, watershed, waterfalls, meanders, and river mouths. It explains that a river's drainage basin is the area that drains into the river and its tributaries, and that waterfalls form when a river flows over mixed hard and soft rocks, eroding the soft rocks more quickly to form a ledge. It also describes how river meanders and oxbow lakes are formed by rivers and that sediments deposited at river mouths over time create deltas with distributaries.

El Gobernador de Sonora anunció tres grandes obras de infraestructura hidráulica como parte de la segunda etapa del proyecto Sonora SI, con una inversión de $3,825 millones de pesos. Las obras incluyen dos acueductos que proveerán agua a varios municipios y una presa para Nacozari de García. El Gobernador también firmó un decreto para crear un fondo que garantice la realización del proyecto Sonora SI, cuyas obras comenzarán en octubre de 2010.
The document summarizes key aspects of water resources and the hydrologic cycle. It describes the hydrologic cycle as the continuous movement of water on, above and below the Earth's surface, changing forms between liquid, solid and vapor. It also outlines the major processes involved like evaporation, transpiration, condensation, precipitation, infiltration and runoff. It provides details on different water reservoirs like oceans, glaciers, groundwater, lakes and rivers. It explains the distribution and movement of water within the hydrologic cycle and between various reservoirs on Earth.
The document summarizes key aspects of the hydrologic cycle and Earth's water systems. It describes the hydrologic cycle as a series of interconnected water storage areas and transfer processes. It discusses the oceans, which contain over 97% of Earth's water, and how ocean waters vary in salinity, temperature, and density around the world. It also outlines various freshwater storage areas like lakes, rivers, groundwater, and glaciers, and how humans have impacted some of these systems through activities like irrigation and groundwater extraction.
Rivers begin as small streams and creeks in headwaters and flow downstream, increasing in width and other factors. The biology changes along the river continuum from the source to mouth, with cooler, clearer water and organisms adapted to fast flow near the headwaters and larger, muddier water with slower flow and different adaptations closer to the mouth. Human activities like pollution, dams, and industry have influenced rivers worldwide.
Rivers begin as small streams in high elevation areas and flow downstream, gradually widening and slowing as they go. They provide important ecosystem services like freshwater, habitat, and nutrient transport. The biology and chemistry of rivers changes longitudinally from headwaters to mouth, with cooler, faster upper reaches containing trout and mayflies while lower stretches have warmer water and fish like catfish. Human activities like pollution, dams, and industry have impacted many of the world's major rivers.
Water resources can be divided into surface sources and subsurface sources. Surface sources include ponds, lakes, streams, rivers, and storage resources like dams. Subsurface sources include springs and wells. Together these natural sources provide most of the planet's fresh water supply, though only a small percentage is readily accessible for human use.
This document summarizes different types of aquatic ecosystems, including freshwater ecosystems like ponds, lakes, streams, rivers, and wetlands, as well as marine ecosystems like oceans, coral reefs, and estuaries. It provides details on the characteristics of each ecosystem, such as the temperature and salinity of freshwater bodies, the diversity of species in oceans and coral reefs, and how estuaries are formed by the mixing of fresh and salt water.
The document discusses various topics related to hydrology and oceanography. It defines hydrology as the study of Earth's water in its different states and how it circulates between oceans, atmosphere, and land. It also defines oceanography as the scientific study of oceans, their physical and biological properties, and the ocean floor. It outlines the major water reservoirs on Earth and describes the water cycle and groundwater systems.

The document discusses various aspects of water including the water cycle, distribution of water bodies, ocean circulation, waves, tides, and ocean currents. The water cycle involves water evaporating from oceans and land into vapor, condensing into clouds, and falling as precipitation. Oceans hold 97.3% of the world's water, mostly as salty water, while fresh water is found in ice caps, groundwater, lakes, and rivers. Ocean circulation involves large scale movements of ocean water in various directions driven by forces like winds, gravitational pulls of the sun and moon, and differences in water temperature.
Lakes and rivers are important bodies of freshwater on Earth. Lakes and rivers contain water, which can exist as a solid, liquid, or gas. While water covers 70% of the Earth's surface, most is saltwater - only 1% of the total water on Earth is freshwater available for human use, found primarily in lakes and rivers. Rivers drain the landscape and transport water and minerals to oceans, beginning as small streams and merging into larger rivers like the Amazon and Mississippi that span great distances. Lakes vary in depth, size, and location around the world, storing about 90% of the Earth's surface freshwater aside from oceans.
Oceanography is the science that studies the oceans along with marine organisms and ecosystem dynamics, ocean currents and waves, plate tectonics and the geology of the sea floor, and the chemical substances and physical properties of the world oceans.
This document discusses different types of hydrometeorological hazards and processes related to the hydrologic cycle. It begins by defining hydrometeorology as the study of atmospheric and terrestrial phases of the hydrologic cycle, focusing on the interrelationship between land and lower atmosphere. It then describes various processes involved in the hydrologic cycle like evaporation, condensation, precipitation, runoff, infiltration and transpiration. The document also discusses different types of clouds and their roles in the cycle. Finally, it covers terrestrial processes like surface runoff, infiltration rates based on soil properties, and factors influencing runoff generation in watersheds.
The document discusses ocean circulation and currents. It describes how surface ocean currents are driven primarily by wind and transfer heat from warmer to cooler areas, affecting coastal climates. Deep ocean currents are driven by differences in water density from factors like temperature and salinity. Major currents include the Gulf Stream and North Atlantic Drift, which form part of the North Atlantic gyre and transport warm water northward.
The document discusses the distribution and composition of Earth's water. It notes that 97% of water on Earth is salt water, with the remaining 3% being fresh water that exists as ice water (79%), groundwater (20%), and surface water (1%). It also discusses various factors that affect bodies of water, including waves caused by wind and lunar/solar gravitational forces, as well as how humans can negatively impact water quality through pollution but also help filter water.
The document discusses the hydrosphere and water pollution. It defines the hydrosphere as the liquid water component of Earth, including oceans, seas, lakes, rivers, and streams, which covers 70% of the planet. The hydrosphere is in constant motion due to ocean currents driven by factors like temperature, salinity, and wind energy transfer. The document then discusses how water pollution has increased as the human population has grown and industrialized, threatening the quality of both surface waters and underground aquifers, with over half of Iowa's groundwater wells found contaminated in 1996.
Grade 11 Chapter 4 Module Earth Science : Water Resourcesyeshynegarin
- Water resources are natural resources that are potentially useful for agricultural, industrial, household, recreational and environmental activities. All living things require water to grow and reproduce.
- Water exists on Earth in different forms and locations, including oceans, atmosphere, ground, and within living things as part of the hydrologic cycle. The hydrologic cycle involves the continuous movement of water between these different reservoirs through various processes like evaporation and precipitation.
- Freshwater, which makes up a very small percentage of the total water on Earth, is found as glaciers, groundwater, atmospheric water vapor, and surface water resources like rivers, lakes, and wetlands that are important for human and other uses.
Ponds are smaller bodies of standing freshwater than lakes. They are often shallow and contain plants, algae, and small aquatic animals. Ponds provide habitat for species like frogs, turtles, and fish. While ponds can be naturally occurring, human activities like roads and overgrazing can negatively impact ponds. The design of a pond determines what wildlife it will support. Ponds are used for aesthetic, agricultural, and wildlife purposes.
The document describes the hydrologic cycle (water cycle) where water is constantly being cycled through the atmosphere, ocean, and land, driven by energy from the sun. Water evaporates from bodies of water and soil into the atmosphere, condenses to form clouds, and falls back to earth as precipitation. Precipitation replenishes groundwater, surface water in streams and rivers, and water in oceans, completing the cycle which is crucial for life on Earth.
