What does it mean when the contour lines are father apart?

When contour lines are farther apart, it indicates a gentle slope or gradual change in elevation in the terrain. This means the change in elevation over a given distance is more gradual.


What is the approximate height of a building when the angle of elevation at the top of a building is 34 degrees and at a point 80 feet closer the angle of elevation is 45 degrees?

It can be shown that:height = (d tan α tan β)/(tan α - tan β)where: α is the angle closest to the objectβ is the angle further away from the objectd is the distance from the point of angle α to the point of angle βThus: height = (80 ft × tan 45° × tan 34°)/(tan 45° - tan 34°) ≈ 165.78 ft


What is the rule of the thumb and where does it come from?

The Texas Rule of Thumb is: The further you travel Northwest, the higher the elevation and lower the precipitation, the further you travel Southeast, the lower the elevation, and higher the precipitation.


What happens to the elevation when the crust thickens?

When the crust thickens, the elevation typically increases due to the isostatic response of the Earth's lithosphere. As the crust becomes more buoyant, it can rise to maintain equilibrium with the underlying mantle. This process is often associated with tectonic activity, such as mountain building or volcanic activity, which can further contribute to increased elevation. Overall, thicker crust generally leads to higher elevations.


Is a star with no measurable parallax is very close to Earth.?

No, if you can measure no parallax, the star is far away - further than a certain distance.


What is the height of a building if the angle of elevation to the top from a point on the ground is 31.4 degrees and from 53 feet further back it is 26.4 degrees?

It can be shown that:height = (d tan α tan β)/(tan α - tan β)where: α is the angle closest to the objectβ is the angle further away from the objectd is the distance from the point of angle α to the point of angle βThus: height = (53 ft × tan 31.4° × tan 26.4°)/(tan 31.4° - tan 26.4°) ≈ 140.87 ft


How do scientists use computers to measure distance from stars?

From what I remember in two geology classes, scientists measure the distance between a star and Earth by comparing "red shift," a shifting of certain bands of light toward the "red" end of the spectrum. The further the shifting, the greater the distance.


How to determine the dip of formation from the geological map?

To determine the dip of formation from a geological map, first identify the strike direction of the rock layers, which is indicated by the orientation of the geological symbols. Next, look for contour lines or symbols that represent the elevation of the formations; the difference in elevation across a horizontal distance indicates the dip. Finally, use the formula for calculating dip, which involves the change in elevation divided by the horizontal distance, typically expressed in degrees. Additionally, any cross-sections included in the map can provide further insight into the dip of the formations.


What is the comparative degree of far?

The comparative degree of "far" is "farther" when referring to physical distance or "further" when referring to metaphorical distance or degree.


What is the land elevation along the coastal plain between?

The land elevation along the coastal plain varies but generally ranges from sea level to a few hundred feet above sea level. The elevation gradually increases as you move further inland from the coast.


Is pressure higher at a lower or at a higher elevation?

Pressure decreases with increasing elevation, so pressure is higher at lower elevations and vice versa. This is because the density of the atmosphere decreases as you move further away from the Earth's surface.


How is elevation represented on a topographic map?

In order to "map" a terrain a cartographer needs to know how high or how low the soil is (land) from sea level. The physical makeup of earth, the physical map of places shows you land formations through the use of color which codes the particular place as being a certain distance above sea level. If the map was coded so that low elevation numbers (valleys) are dark and high elevations (mountains, peaks, plataues) are light, what you end up with is an image (likely shaded) which represents the "relief" of the place. Relief means 3 dimensional or sculptured in art. You can think of a map as a kind of art of the 3 dimensional physical world.
