Which of the following best describes the distribution of water on Earth?
Water is evenly distributed across Earth
. … Most of the Pacific Ocean and Indian Ocean comprise the so-called “water hemisphere.” Most of Earth’s water is freshwater and is predominately stored in the many lakes around the world.
What is the distribution of water bodies on our Earth?
Water distribution
The distribution of water on the Earth’s surface is extremely uneven. Only
3% of water on the surface is fresh
; the remaining 97% resides in the ocean. Of freshwater, 69% resides in glaciers, 30% underground, and less than 1% is located in lakes, rivers, and swamps.
How does water is being distributed?
In urban and suburban areas, water is distributed from
the source through large underground pipes
, called water mains, under the streets. … Most of the water that is used inside homes or schools remains liquid. It flows through drainpipes into a municipal sewer system or into a septic system connected to the building.
Which best describes 97% of Earth’s water?
97% of total water on Earth is
salt water
, and most of the remaining 3% is freshwater frozen in ice caps and glaciers.
What is the process involved in the distribution of water in Earth?
water cycle, also called
hydrologic cycle
, cycle that involves the continuous circulation of water in the Earth-atmosphere system. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff.
What is the most important factor which affects the distribution of water on the earth?
Climate –
low levels of rainfall and high temperatures
lead to water deficits . When rainfall is low, there is less water available. When temperatures are high, water evaporates and so there is less available to use. Water surpluses are common where rainfall is high and temperatures are lower.
What is the most abundant type of water on Earth?
The vast majority of water on the Earth’s surface, over 96 percent, is
saline water in the oceans
.
What is the cause of unequal distribution of water?
Water is unevenly distributed around the world. …
Over time, there will be less water per person within many river basins as the population grows and global temperatures increase so that some water sources are lost
. Over time, many nations, even developed nations, are projected to have less water per person than now.
Where is Earth’s water found?
Earth’s water is (almost) everywhere:
above the Earth in the air and clouds
, on the surface of the Earth in rivers, oceans, ice, plants, in living organisms, and inside the Earth in the top few miles of the ground.
What is the importance of knowing the distribution of water on Earth?
The distribution of water throughout the atmosphere and how it moves, changing between its solid, liquid, and gaseous forms, is
a powerful vehicle for redistributing Earth’s energy and influences the behavior of the planet’s weather, climate, and other environmental systems
.
Is Earth’s water finite?
Fresh water is vital to life and yet
it is a finite resource
. Of all the water on Earth, just 3% is fresh water. Although critical to natural and human communities, fresh water is threatened by a myriad of forces including overdevelopment, polluted runoff and global warming.
What is the main source of water on Earth?
Complete answer: The main source of water is
the rainwater
. The water cycle is a process that involves evaporation, condensation and precipitation and the output is rainwater. The water source is important in the water cycle. The water resources are lake, pond, canal, the river from where water evaporates.
Are we losing water on Earth?
The Central Valley Aquifer in California underlies one of the nation’s most agriculturally productive regions, but it is in drastic decline and has
lost about ten cubic miles of water in just four years
.
What is water cycle with diagram?
The water cycle is defined as a
natural process of constantly recycling the water in the atmosphere
. It is also known as the hydrological cycle or the hydrologic cycle. During the process of the water cycle between the earth and the atmosphere, water changes into three states of matter – solid, liquid and gas.
What is water cycle for kids?
The water cycle is
the path that all water follows as it moves around Earth in different states
. … Water can be found all over Earth in the ocean, on land and in the atmosphere. The water cycle is the path that all water follows as it moves around our planet.
What are the two types of water available on Earth?
The world’s water exists naturally in different forms and locations: in the air, on the surface, below the ground and in the oceans. Just 2.5% of the Earth’s water is
freshwater
, and most is frozen in glaciers and ice sheets. About 96% of all liquid freshwater can be found underground.
