This pie chart displays the makeup of Earth's water. Which sentence is true about Earth's water, based on the data in the pie chart?

• Over 30% of fresh water humans use comes from lakes and rivers

• Humans use a much greater percentage of salt water than fresh water

• Fresh water makes up 2.5% of the water on Earth so it should be conserved

• Most of Earth's total water is frozen in ice glaciers, which are made of salt water

Less than 3% of the Earth's water supply is fresh water. Only about 0.3% of this supply is surface water, found in rivers, lakes, and swamps. This pie chart shows how this small percentage of surface water is distributed. Based on the data shown, which statement is true?

• The majority of Earth's rivers and swamps are found in North America and Africa

• The North American Great Lakes is Earth's third-largest fresh surface water source

• The North American Great Lakes and Lake Baikal hold 50% of Earth's fresh surface water

• The amount of fresh surface water in swamps and rivers is equal to that of Lake Baikal
