# What is the total amount of global evaporation?

## What is the total amount of global evaporation?

Total annual evapotranspiration amounts to approximately 505,000 km3 (121,000 cu mi) of water, 434,000 km3 (104,000 cu mi) of which evaporates from the oceans. 86% of global evaporation occurs over the ocean.

### What percentage of global precipitation falls on land compared to oceans?

Evapotranspiration from land — in context Of the global rainfall amount, 77 percent of precipitation falls over oceans and 23 percent over continents. Because some continental precipitation runs off to the seas, 83 percent of global evaporation comes from the oceans and only 17 percent from continents.

What percentage of global precipitation occurs over land?

falls on the land compared to falling on the oceans? 13 percent 22 percent 35 percent 48 percent Although land makes up about 30% of the. precipitation. Only about 22% is transported over land to fall as rain or snow there. SPOT CHECKING.

What is the meaning of global precipitation?

Global Precipitation Measurement (GPM) is a joint mission between JAXA and NASA as well as other international space agencies to make frequent (every 2–3 hours) observations of Earth’s precipitation.

## What percentage of the world’s precipitation falls into the oceans 85% 90% 75%?

~96.5% of the world’s water is held in the oceans. ~90% of evaporated ocean water leads to precipitation over the oceans. ~77% of precipitation falls over the ocean.

### Where is most of the water on Earth stored?

The ocean
The ocean holds about 97 percent of the Earth’s water; the remaining three percent is found in glaciers and ice, below the ground, in rivers and lakes. Of the world’s total water supply of about 332 million cubic miles of water, about 97 percent is found in the ocean.

Does most precipitation fall in the ocean?

Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as surface runoff. A portion of runoff enters rivers in valleys in the landscape, with streamflow moving water towards the oceans.

What has happened to global precipitation patterns during the last 100 years?

What has happened to global precipitation patterns during the last 100 years? There is less precipitation all around the world. Some parts of the world are seeing more precipitation than ever before while other parts are seeing less.

## What percent of precipitation falls on the ocean?

78%
The ocean plays a key role in this vital cycle of water. The ocean holds 97% of the total water on the planet; 78% of global precipitation occurs over the ocean, and it is the source of 86% of global evaporation.

### What are the 5 places water is stored on Earth?

How much precipitation does the US get per year?

On average, total annual precipitation has increased over land areas in the United States and worldwide (see Figures 1 and 2). Since 1901, global precipitation has increased at an average rate of 0.10 inches per decade, while precipitation in the contiguous 48 states has increased at a rate of 0.20 inches per decade.

How does the amount of precipitation change over time?

This figure shows how the total annual amount of precipitation in the contiguous 48 states has changed since 1901. This graph uses the 1901–2000 average as a baseline for depicting change. Choosing a different baseline period would not change the shape of the data over time. Figure 2. Precipitation Worldwide, 1901–2019

## How are precipitation anomalies determined in the United States?

Anomalies for the contiguous 48 states and Alaska have been determined by calculating average precipitation anomalies for areas within each state based on station density and topography. These regional anomalies are then averaged together in proportion to their area to develop national results.

### How does precipitation affect human well-being and ecosystem?

Precipitation can have wide-ranging effects on human well-being and ecosystems. Rainfall, snowfall, and the timing of snowmelt can all affect the amount of surface water and groundwater available for drinking, irrigation, and industry.
