The equivalent widths of MgII absorption in the circumgalactic medium (CGM)trace the global star formation rate up to $z<6$, are larger for star-forminggalaxies than passively-evolving galaxies, and decrease with increasingdistance from the galaxy. We delve further into the physics involved byinvestigating gas kinematics and cloud column density distributions as afunction of galaxy color, redshift, and projected distance from the galaxy(normalized by galaxy virial radius, $D/R_{\rm vir}$). For 39 isolated galaxiesat $0.3<z_{\rm gal}<1.0$, we have detected MgII absorption in high-resolution($\Delta v\simeq 6.6$ km/s) spectra of background quasars within a projecteddistance of $7<D<190$ kpc. We characterize the absorption velocity spread usingpixel-velocity two-point correlation functions. Velocity dispersions and cloudcolumn densities for blue galaxies do not differ with redshift nor with$D/R_{\rm vir}$. This suggests that outflows continually replenish the CGM ofblue galaxies with high velocity dispersion, large column density gas out tolarge distances. Conversely, absorption hosted by red galaxies evolves withredshift where the velocity dispersions (column densities) are smaller (larger)at $z_{\rm gal}<0.656$. After taking into account larger possible velocities inmore massive galaxies, we find that there is no difference in the velocitydispersions or column densities for absorption hosted by red galaxies with$D/R_{\rm vir}$. Thus, a lack of outflows in red galaxies causes the CGM tobecome more quiescent over time, with lower velocity dispersions and largercolumn densities towards lower $z_{\rm gal}$. The quenching of star formationappears to affect the CGM out to $D/R_{\rm vir}=0.75$.
