The largest mountains on the continents are formed by stress deformation.
This is also know as strain, which is a process that occurs when the intensity of the stress is greater then the internal strength of the rock. This kind of activity, forming of mountains, occurs when to tectonic continental plates with same densities are colliding, so under the pressure, stress, they create, the area of collision is lifting up.
1. Inner core
Made of solid iron about 1,200 km thick. temperature is about 7,000 degrees Celsius.
2. Outer core
Very dense liquid of iron and sulphur about 2,250 km thick. Temperature is about 4,000 degrees Celsius.
3. Lower Mantle
Solid rock about 2,200 km thick. Temperature is about 3,000 degrees Celsius.
4. Upper Mantle
Solid rock about 720 km thick that flows from plasticity. Temperature is about 850 degrees Celsius
5. Crust
Plates that average bout 30km in thickness and 25 degrees Celsius in temperature.
The three types are divergent, convergent, and transform boundaries.
Answer:
with the help of ecolocation process like most using sound wave for example ultrasound is used to calculate ocean depth it has high frequency
Explanation:
a fathometer device is used .let the downward distance travelled use to bed of the ocean by the wave be d .when these waves reflect back from the bed of ocean and received by fathometer the upward distance travelled is also d hence total distance travelled is equal to 2d. if v be the velocity of waves in water and t be the the time taken for the waves to reach back to the fathometer the from the definition of speed
speed =distance travelled÷ time taken=2d÷t
d=v×t÷2
