EVERYDAY SCIENCE

Detailed explanation-1: -The complete sentence is: Earth scientists often use a model to represent complex objects or processes.

Detailed explanation-2: -Scientific models are representations of objects, systems or events and are used as tools for understanding the natural world.

Detailed explanation-3: -Earth system models can help understand and provide critical information on water availability, drought, climate and temperature extremes, ice sheets and sea levels, and land-use change. They help scientists understand how plants, people, animals, and microbes all contribute to and are affected by the Earth’s climate.

Detailed explanation-4: -There are three types of models that are generally grouped. They include visual models, mathematical models, and computer models. All three types of models can be used in every branch of science. Each depends largely on the type of scientific inquiry and the form of the data collected.

Detailed explanation-5: -Earth system models and climate models are a complex integration of environmental variables used for understanding our planet. Earth system models simulate how chemistry, biology, and physical forces work together. These models are similar to but much more comprehensive than global climate models.
