module 1 Planet earth

what is the relationship between gravity and mass.

• less mass=  more gravity
• more mass  = less gravity
• less mass = more weight
• more mass = more gravity

accretion is best described as

• the evolution of the solar system

• a process of the accumulation of small pieces into larger peices

• a process by which a star begins its nuclear reactions

• a band of colour produced by passing white light through a prism

the age of the earth can be determined using

• radioactivity

• seismic data

• salt concentration of the oceans

• banding substrate of the stratification composition

differentiation is best described as

• the layering of earth

• identifying differences in minerals

• process of accumulation of small pieces into large pieces

• a band of colour produced by passing white light through a prism

which of the following pairs of rocks include one igneous and one sedimentary rock

• shale and slate

• mica and conglomerate

• granite and gneiss

• limestonr and basalt

identify the property of rocks that is best used during correlation

• colour

• type of rock

• fossils

• grain size

identify the list that only contains renewable resources

• vegetables, wool, diamonds, water

• steel, coal, diamonds, plastic

• paper, wool, vegetables, water

• plastic, natural gas, cotton, paper

Igneous rocks are usually identified by

• their crystal size

• the minerals they contain

• their crystal size and minerals they contain

• their crystal size, minerals they contain and their location.

percentage of moisture in a soil sample can be estimated by measuring the change in mass before and after

• strongly heating a dried soil sample

• strongly heating a wet soil sample

• strongly heating a fresh soil sample

• gently heating a wet soil sample

identify which of the following is identified by radiometric dating

• relative date

• type of rock

• absolute date

• mineral content
