49. which is not characteristic of an lava flows? blocky, elinkery surface fast moving e, steep front d. relatively viscous lava

C. surface fast moving

Explanation:

Lava is characterized by molten rock that is generated by geothermal energy and ejected through the planetary crust, having temperature usually 700 to 1200 degrees celsius. Explosive eruptions in the form of volcanic ash and tephra, volcanic lava is composed of silicate elements, including felsic lava, 750 degrees intermediate lava, 950 degrees, Mafic lava of above 950 degrees and ultramafic i.e 160 degrees. Volcanic lava tends to be slow, cloggy, and semi-solid blocks. Tends to flow easily from a channel and classified as Aa, Pāhoehoe, Block, Dome, and Pillow lava. Lavas are enormously destructive in their paths they destroy everything and hence usually very slow-moving and characterized based on its viscosity of flow.
