Main Difference
The main difference between Slush and Smoothie is that the Slush is a mixture of snow and liquid water and Smoothie is a drink.
Slush
Slush, also called slush ice, is a slurry mixture of small ice crystals (e.g., snow) and liquid water.In the natural environment, slush forms when ice or snow melts. This often mixes with dirt and other materials, resulting in a gray or muddy brown color. Often, solid ice or snow can block the drainage of fluid water from slushy areas, so slush often goes through multiple freeze/thaw cycles before completely disappearing.
In areas where road salt is used to clear roadways, slush forms at lower temperatures than it would ordinarily in salted areas. This can produce a number of different consistencies over the same geographical area.
Smoothie
A smoothie is a thick and creamy beverage made from pureed raw fruit, vegetables, and sometimes dairy products (e.g. milk, yogurt, ice-cream or cottage cheese), typically using a blender. Smoothies may be made using other ingredients, such as water, crushed ice, fruit juice, sweeteners (e.g. honey, sugar, stevia, or syrup), whey powder, plant milk, nuts, nut butter, seeds, tea, chocolate, herbal supplements, or nutritional supplements. A smoothie containing dairy products is similar to a milkshake, though the latter typically contains less fruit and often uses ice cream or frozen yogurt.
