A mysterious black line in the sky could be caused by a phenomenon such as a contrail from an aircraft, a shadow cast by a cloud, or a solar eclipse.
A large crack in the ground formed by a river is called a gorge or canyon. If it is formed by a series of earthquakes, it is called a fault line or fissure.
A line of violent thunderstorms is called a squall line. It is a long, narrow band of severe thunderstorms that can produce damaging winds, large hail, and sometimes tornadoes. Squall lines often form along or ahead of cold fronts.
Earthquakes occur at long narrow fractures in the Earth's crust called faults. As tectonic plates shift past each other, stress builds up at these faults until it is released in the form of an earthquake. Movement along the fault line causes the ground to shake, resulting in seismic waves that can be felt at the surface.
I would draw the line at the base of the lithosphere, which is known as the lithosphere-asthenosphere boundary. This boundary separates the rigid lithosphere from the more plastic asthenosphere below it.
The first line is "A narrow fellow in the grass".
An A line is a piece of garment that is slightly flared from narrow shoulders or waist.
a long, narrow mark or band.
The base line is the end line on both sides of the court.
You can detect a black line on a white surface using infrared sensors that can distinguish the color contrast between the line and the surface. The sensors can detect the different reflectivity levels of the two colors and help the robot follow the line accordingly. Employing a PID (Proportional Integral Derivative) control algorithm can also assist in keeping the robot aligned with the black line.

Yes a straight line is considered an angle as the line which is inclined on the base line has 0degree angle on the base line .
Black Line happened in 1830.
The river had carved a wide canyon through the relatively softer sedimentary rock. Cell phones rely on a direct line of sight, and may not work in a mountain canyon.
A long narrow mark could be a scratch on a surface, a streak of light, or a thin line drawn with a writing implement.
No, with modifications. Norway has a government which its core platform is built on Marxist ideas, namely socialism. The line between communism and socialism is in many instances very narrow. In Norway's case this line is narrow!
