First, surface water.

Let's call it area surface.

0.3 of all fresh water is surface water.

So surface area, if you increase the surface area of interaction, then you'll also increase the reaction rate.

The surface area in the pie shown in red really corresponds to 8 12 of the total surface area.

There is no surface fresh water.

Water is scarce in this area.

Water is scarce in this area.

She sank under the surface of the water.

Land and water make up the earth's surface.

The wind ruffled the surface of the water.

The surface of the earth is 70 water.

Three fourths of the earth's surface is water.

Water makes up most of the earth's surface.

Below the surface there is hard saline water.

112 feet high, and a 12,000acre water surface.

If you increase the surface area so we were just doing gas gas interactions, which almost by definition have pretty good surface area interactions.

There's a water shortage in this area.

This is called kund. We have, in English, surface water and ground water.

Three quarters of the surface of Earth is water.

What is going to be the surface area of this ring?

What is the total surface area that she has to paint?

A fallen leaf floated on the surface of the water.

The surface of a planet is composed mostly of water.

About three fourths of the earth's surface consists of water.

Three fourths of the earth's surface is covered with water.

Two thirds of the earth's surface is covered with water.

Three quarters of the surface of the Earth is water.

So, there is a lot of water below the surface.

The pebble I threw skipped along the surface of the water.

Sub surface water on Mars, frozen in the form of ice.

Well, that's less than one percent of the surface area of the bay.

And the last one, and you probably realize this, is just the surface area.

All the liquid water above ground is surface water and it is a tiny blip of an amount.

People living in this area are dying for want of water.

100, 400, 2000, and 700 in terms of the surface area that the fire occupied.

So the surface area of this cube right over here is going to be 6.

So for this cube, the surface area is going to be 6 times 2 squared.

It's invisible to us, but it is much more plentiful than surface water.

We have this road going around the area, which brings the people electricity and water from our own area.

However, by breaking up the clumps into individual particles, the total surface area is increased, and each particle has an exposed surface that can react.

And then the surface area of this cube is going to be 6 times 1.5 squared.

And notice when we did surface area. We got our answer in terms of sq cm.

But if the surface area goes up, then the reaction also goes up, the reaction rate.

And other observations have revealed the red planet may still contain water below surface.
