Final answer:

The major types of physical and biological evidence for climate change include temperature records, ice core samples, and changes in plant and animal behavior.


Step-by-step explanation:

The major types of physical and biological evidence for climate change include temperature records, ice core samples, and changes in plant and animal behavior.

Temperature records show that the Earth's average temperature has been increasing over the past century. This can be observed through measurements from weather stations, satellites, and other instruments.

Ice core samples provide a record of past climate conditions by analyzing the composition of ice layers. The layers contain indicators of temperature, greenhouse gas concentrations, and other climate variables.

Changes in plant and animal behavior can also provide evidence of climate change. For example, some bird species are migrating earlier in the spring because of warmer temperatures, and plants are blooming earlier.
