Buttes usually have a hard, erosion-resistant cap rock on the top.

The dominant rock in the park is granite, which is very hard and erosion-resistant.

However, most of the rocks have one thing in common; the rocks are generally hard and erosion-resistant.

They are often fitted with erosion-resistant liners to extend rotor life.

The range consists almost exclusively of Table Mountain sandstone which is extremely erosion-resistant.

The top rock formation was composed of erosion-resistant limestone and Lockport dolostone.

Christensen also developed an erosion-resistant matrix for diamond bits and introduced the 250P-core barrel system that quickly became the industry standard.

Usually an erosion-resistant rock layer also has a more gentle slope on the other side of the ridge called a dip slope.

The sides of the basin are defined by the patchy remains of relatively erosion-resistant formations.

The upper and lower layers are softer than the middle, which creates a short stretch of erosion-resistant creekbed between two waterfalls.

The distinct shape of these rocks comes from an erosion-resistant layer of rock atop softer sandstone.

Caprock: A stratum of erosion-resistant sedimentary rock (usually limestone) found in arid areas.

Popularly mistaken for a volcano, it is in fact an erosion-resistant metamorphosed sedimentary deposit from the deep sea.

Limestone was crushed into a powder on the Mission grounds to create a mortar that was more erosion-resistant than the actual stones.

The hills are composed of trap rock which is an erosion-resistant, fine-grained mafic volcanic rock.

The two units accumualate on the erosion-resistant layer beneath, the cliff-forming Tapeats Sandstone.

Wills Mountain is capped by the erosion-resistant Silurian Tuscarora quartrzite.

If a plug is preserved, erosion may remove the surrounding rock while the erosion-resistant plug remains, producing a distinctive landform.

Both Sugarloaf Mountain and Mount Toby are composed of erosion-resistant sedimentary rock.

The erosion-resistant quartz has lasted to this day and can be seen in many places in the Taunus, but nowhere is it more spectacular than here.
