Respuesta :
Earthquake occurs due to friction between tectonic plates. The correct options are:
- First blank: Option C: A transform boundary causes excessive amounts of friction between two tectonic plates,
- Second blank: Option B: tsunami
When does earthquake happens?
An earthquake occurs when the Earth's crust moves suddenly. As the tectonic plates grind against each other, pressure builds up. Earthquake can occur when the plates collide, spread etc.
The options for first 'blank' space are:
- a. A volcanic island moves away from a hotspot and it goes extinct
- b. The solid rock layer in the lithosphere is no longer influenced by the more fluid asthenosphere,
- c. A transform boundary causes excessive amounts of friction between two tectonic plates,
- d. A divergent boundary abruptly reserves rolls to become a convergent boundary
Thus, correct statement would be:
Earthquakes sometimes occur when A transform boundary causes excessive amounts of friction between two tectonic plates.
(option C)
Now, the second blank has options:
- a. an avalanche,
- b. a tsunami,
- c. a tidal wave,
- d. a landslide
It asks the name for "some underwater earthquakes shake the ocean floor and cause large sea waves that destroy property and threaten lives. such a sea wave is called "
- Tidal waves are caused by gravity of heavenly bodies, mainly moon.
- Landslide is sliding of land from hillside etc places.
- Avalanche is falling of snow, rock and ice from a mountain or hill type region.
- Tsunami is correct option here, it is caused because of shaking of ocean floor.
Thus, Option B: A tsunami is correct.
Thus correct statement would be:
some underwater earthquakes shake the ocean floor and cause large sea waves that destroy property and threaten lives. such a sea wave is called a tsunami
Thus, the correct options are:
- First blank: Option C: A transform boundary causes excessive amounts of friction between two tectonic plates,
- Second blank: Option B: tsunami
