Carbonation:

Column B
a.A physical process: Slow cracking of rock when ocean water seeps in, creating mineral crystals that cause the crack to deepen.
b.A physical process: The slow cracking of rock by having water seep into cracks and expand when it freezes
c.A chemical process in which matter reacts with oxygen, typically creating a more brittle substance afterwards, and most often, rust!
d.A chemical process in which carbon dioxide dissolves into water, producing carbonic acid. Ex: Limestone caves!

Question 22 (1 point)
Which statement about how Weathering and Erosion interact with Earth's Spheres is Correct? Weathering and Erosion | Science Lesson For Kids | Grades 3-5

a
Weathering and Erosion is the destruction of the biosphere, caused by massive changes in the composition of the atmosphere, hydrosphere and lithosphere
b
Weathering and Erosion is the breaking of the lithosphere (geosphere), which is caused by weathering agents from the biosphere, hydrosphere and atmosphere
c
Weathering and Erosion is the polluting of the atmosphere, caused by the industries of the hydrosphere, biosphere and lithosphere
d
Weathering and Erosion is the carbonation of the hydrosphere, caused by the pollution of the atmosphere, biosphere and lithosphere
