Answer:
Yes
Explanation:
Oceanic crust is denser than continental crust because it is made of basaltic rock. Basaltic rock is denser than silicate rocks which make up continental crust.
For this reason, it can be said that the continental crust is more 'buoyant' than the oceanic crust. Thus, when the two crusts meet at a subduction zone and collide, one of them has to give way. The denser crust ends up subducting (giong underneath) the less dense crust, and the continental crust gets pushed up to form mountain ranges like the Andes or the Rockies.
Answer:
sound pulse travels from a ship to the seafloor and back
Explanation:
An echo sounder employees techniques used in measuring the depth of the water body. Sound waves are usually passed from the ship into the sea and the time required for the waves to travel from the ship to the sea floor and back is usually recorded.
It is used in the calculation of the speed of sound in water at that point in time which varies according to the depth and physical characteristics of the water body involved.
Hail forms when its is A. SUPER cold and B they first have to accumulate into raindrops and then freeze, so basically they water molecules are just forming into regular rain and then the temperature suddenly drops the raindrops freeze and turn into hailstones.
Hope that helps!
Answer:
The Sun's temperature, which reaches around 15 million degrees Celsius in its core, steadily decreases with distance from the core, falling to 6000°C at its 'surface'. ... Instead, it rises to about 10,000°C in the chromosphere, and exceeds a million degrees Celsius in the corona.
