What is the range of FM and Am broadcaster in km?
The range of FM and AM broadcaster in kilometres ranges from 6 to 70 kilometres.
How thick is earths crust?
The continental crust, (where all the land is) is generally around 30 km (20 mi) to 50 km (30 mi) thick. The oceanic crust (the bottom of the sea) is roughly 5 km (3 mi) to 10 km (6 mi) thick.
Which layer is with its characteristic?
answer Mantle: Convection here leads to earthquakes Crust: Ranges from 6 km to 70 km thick Core: Has a liquid and solid layer Moho Barrier: Separates the crust and mantle The core has a liquid layer and a solid layer. The mantle has convection cells that lead to earthquakes. The Moho Barrier separates the mantle and the crust. The crust is the thinnest layer, ranging from about 6 km to 70 km in thickness
How thick is the earth's curst?
The crust consists of two parts: the oceanic and the continental crust. All of these values vary slightly, of course, but oceanic crust is generally 4 - 7 miles (6 - 11 km) thick, whereas continental crust is much thicker, averaging 20 - 25 miles (30 - 40 km), reaching a maximum of 45 miles (70 km) beneath large mountain ranges (having to do with tectonics and isostacy, the "roots" of a mountain range).
How thick is the earths continental crust in km?
Earth is 24,000 kilometers in Circumference. C = Pi times r. So r = 24,000 / 3.14159 or a radius of just about 8,000 kilometers wide. A radius of 8,000 kilometers amounts to the Diameter of 16,000 km. The thickness of Earth's crust varies as per Location.
How thick are oceanic plates?
The oceanic crust is typically between 5 km (3 mi) to 10 km (6 mi) thick.
The average thickness of the crust is?
Oceanic crust is typically 6-10 km thick. Continental crust is typically 35-40 km thick, but can be a lot thicker below mountains. High mountains also have deep roots that enable them to "float" higher on the Asthenosphere. The crust there can be up to about 70 km thick or more. Note that not all crust covered by the sea is oceanic crust. Some continental shelves extend beyond the part of the continent that is above water. For example between Australia and Papua New Guinea and between Malaysia / Cambodia / Indonesia. The satellite view of Maps.google.com clearly shows how the continental shelf is extended beyond the landmass.
How does the earths mantle differ from its crust?
Inner core: 2450 km thick Outer core: 2300 km thick Lower mantle: 2500 km thick Upper Mantle: 400 km thick continental crust: 30-70 km thick Oceanic Crust: 6 km thick
How long 450 km away going 70 km per hour?
we know that, speed=distance / time time = 450/90 = 5 hr
How thin is the earth's crust at the mariana trench?
The surface of the earth is made up of two layers:- the oceanic crust and the continental crust. The oceanic crust is between 6-10km in thickness while the continental crust may be up to 70 km thick. by SVM
How long does it take to drive 14km at 70km an hour?
70 km = 1 hour = 60 min so 7 km = 6 min so 14 km = 12 min Answer: twelve minutes
Is the continental crust more dense than the oceanic crust?
Oceanic crust is thinner (about 6-8 km in total) and more dense. Continental crust is about 30-50 km thick.
