Whenever condensation was observed, a circular patch of dry lid, several millimetres in diameter larger than the seed, surrounded where the seed contacted the lid.
Narrow millimetre-thick epidote veins are associated with brittle shear planes and faults.
Reflectance spectra were measured for small rock chips (a few millimetres across), while emittance spectra were measured for the whole rock sample (y2 cm across).
These fossils range in size from millimetre-scale up to 2 cm in width.
The typical spot size on the target was in the millimetre range.
In addition to being endangered by other insects, a larva which can only burrow a few millimetres may be subjected to considerable changes of temperature.
The central depression is typically a fraction of a millimetre in diameter but may be up to 2 mm.
The amount of moisture was expressed as millimetres of dew.
