  Spicules are the thin hair/grass-like structures that are prominently
observed at the chromospheric solar limb. It is believed that fibrils and rapid
blueshifted and redshifted excursions (RBEs and RREs; collectively referred to
as REs) correspond to on-disk counterparts of type I spicules and type II
spicules, respectively. Our investigation focuses on observing the response of
these REs alongside similar spectral features in the chromosphere, transition
Region (TR), and corona, utilizing space-time plots derived from coordinated
observations from Swedish 1 m Solar Telescope/H{\alpha}, Interface Region
Imaging Spectrograph (IRIS), and Solar Dynamics Observatory. Our analysis
reveals upflowing REs, promptly reaching temperatures characteristic of the TR
and corona, indicating a multi-thermal nature. Similarly, downflowing features
exhibiting similar spectral signatures over the disk display plasma motion from
the corona to chromospheric temperatures, demonstrating a multithermal nature.
In addition to distinct upflows and downflows, we observe sequential upflow and
downflow along the same path, depicting a distinctive parabolic trajectory in
space-time plots of observations sampling TR and various coronal passbands.
Similar to isolated upflows and downflows, these REs also exhibit a
multi-thermal nature throughout their trajectory. Furthermore, our results
reveal a more intricate motion of the REs in which both upflow and downflow
coexist at the same spatial location. On a different note, our analysis,
utilizing coordinated IRIS spectral observations, shows spatio-temporal
redshifts/downflows in both the TR and chromosphere, suggesting that at least
subsets of the strong redshifts/downflows observed in TR temperature spectra
result from the return from the upper atmosphere flow of plasma in the form of
bundles of spicules or features exhibiting similar spectra.
