Which type of evidence acts as a record of changes in species over time and indicates major changes in Earth's surface and climate? A. Fossil record B. Movement of continents C. Ripple marks and mud cracks D. Composition of ice core samples

A. Fossil record

Explanation :

A fossil can be defined as any preserved element (e.g., bones, exoskeletons, shells, animal imprints) which can be used to demonstrate the existence of organisms from past geological periods. The totality of fossils accumulated in a particular area is referred to as the fossil record. The fossil record is very useful in geology and paleontology because the information provided by the fossils helps to place geological events and species in their corresponding geologic eras and periods.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
