Verified step by step guidance

Understand the composition of Earth's water: Earth's water is divided into salt water and fresh water. Salt water is primarily found in oceans and seas, while fresh water is found in rivers, lakes, and glaciers.

Recognize the distribution of water types: Approximately 97% of Earth's water is salt water, which is found in oceans and seas. The remaining 3% is fresh water, which is found in glaciers, ice caps, groundwater, and surface water.

Identify the correct percentage: Given the options, the correct percentage of Earth's water that is salt water is 97%. This is based on the known distribution of water types on Earth.

Consider the implications: Understanding the distribution of salt water versus fresh water is important for environmental science, resource management, and understanding the Earth's ecosystems.

Reflect on the importance of fresh water: Although fresh water makes up only a small percentage of Earth's total water, it is crucial for human consumption, agriculture, and sustaining terrestrial life.
