Mud cracks
Sep 29, 2023 · Multi-billion-year-old mud cracks on the surface of Mars are helping researchers piece together the ancient history of our planetary neighbor’s climate. Observed by NASA’s Curiosity rover in ... An oscillatory crack traveling in a thin plate between two free edges or between two other cracks will release strain energy more efficiently by curving toward either boundary. That is the physics behind the appearance of T-junctions in mud cracks. However, the total strain energy density is higher near the middle of a plate than near the edges.Ripple Marks Mud craks adalah perlapisan sedimen yang terbentuk akibat air yang mengandung banyak lumpur mengering oleh pengaruh udara. Sedimen ini biasanya menghasilkan bentukan-bentukan poligonal. Mud Cracks Lamination atau laminasi adalah struktur lapisan sedimen yang menunjukkan perlapisan yang sejajar (horizontal).

Cracks on a sagging or bowed ceiling. If a ceiling is bowed, sagging, or dropped down, then the reason may relate to structural issues. Common causes include: 1. Spacing of ceiling joists or trusses. If the ceiling joists or trusses supporting the ceiling drywall are spaced too far apart, then sagging may result and the stress from this may ...On Earth, initial mud cracks in mud form a T-shaped pattern, but subsequent wetting and drying cycles cause the cracks to form more of a Y-shaped pattern, which is what Curiosity observed. Additionally, the rover found evidence that the mud cracks were only a few centimeters deep, which could mean that wet-dry cycles were seasonal, or may have ...Deep, irregular cracks resembling dried mud in the dry paint film.
