I think it's an index contour, but I'm not sure.
Elevation can be expressed using various units depending on the region and context. Common units include feet, meters, and kilometers. In aviation, elevation is often measured in feet above sea level, while in geology and geography, it is commonly measured in meters or kilometers above sea level. Additionally, some regions may use specific units like fathoms or leagues to express elevation.
In geology, elevation refers to the vertical height of a location above sea level. It is commonly expressed in units like meters or feet and is used to describe the terrain's height or altitude. Elevation influences climate, ecosystems, and the distribution of geological features.
elevation
the measure of change in elevation in a certain distance is called gradient
Momentum is defined as mass times velocity, and it requires units of mass times units of velocity. The SI unit is kilograms x meters / second. There is no special name for this combination of units. Impulse (force times time) has the same units.
A contour line on a topographic map is typically labeled with the elevation in round units. This helps to indicate the elevation of the land and the change in elevation across the map.

it is something i would know if i paid attention is science class. thats all i can say
just units
"Gradient" of a point quantity is a measurement of how fast it changes in a specific direction. For topography, the gradient of the land is its slope in some direction. It would work out to be dimensionless, because it has to be change in elevation/distance which is length/length no matter what units you use for the elevation or distance.
Because it is a length and so must have units of length.
Mass is typically labeled in units of kilograms (kg) or grams (g).
Relief is the difference in the highest and lowest elevation of a region. Relief is therefore measured in units of length (e.g. meters). Relief controls erosional rates of an area. Slope is the spatial variability of elevation. Slope is measured in units of length per length (e.g. cm/km). Slope controls the local stability of landscapes and therefore, sediment transport. Example of relief: The relief from the top of the mountain to the bottom of the valley is 500 meters. Example of slope: The slope of the Amazon drainage basin varies from 4 cm/km to 1.5 cm/km from the Andes to the mouth of the Amazon river.
Hz is hertz which measures sound.

Whenever you are answering volume questions, it's always units cubed (^3).
A thicker line that has numbers written on it showing the rising or decreasing elevation on a topographic map By Ash Every fifth contour line on a topographic map, usually thicker, used to label elevation.
