Earth Science Basics

A student examined a patch of mud and recorded several statements about footprints in the mud. Which statement is most likely an inference?

• there are five footprints in the mud

• the depth of the deepest footprint is 3 cm

• the footprints were made by a dog

• the footprints are oriented in an east-west direction

Science investigators initially use classification systems to

• extend their powers of observation

• make more accurate inferences

• organize their observations in a meaningful way

• make direct comparisons with standard units of measurement

A student measures and records the temperature of water in a beaker for 8 minutes as shown. What is the average rate of cooling for the water in the beaker during the 8-minute time interval?

• 3.2 ^oC/min

• 3.6 ^oC/min

• 4.5 ^oC/min

• 4.0 ^oC/min
