A)
Hawaiian shield volcanoes are eroded by steams that form deeply carved valleys with steeply sloping heads.
B)
The surrounding areas can remain highlands, lava ridges or mesas.
C)
Stratovolcanoes produce lava flows that initially follow valleys but are highly resistant to erosion.
D)
The system of streams on a dissected volcano cone is not a radial drainage pattern.

Correct Answer :   The system of streams on a dissected volcano cone is not a radial drainage pattern.

Stratovolcano, also known as acomposite volcano, is aconical volcanobuilt up by many layers (strata) of hardened lava, tephra, pumice and ash. Because it is stratified, therefore it  will definitely  form  a volcano cone.

A)
Teflon
B)
Carbon
C)
Silicon
D)
Gallium

Correct Answer :   Silicon

Crystalline silicon cells are made of silicon atoms connected to one another to form a crystal lattice. This lattice provides an organized structure that makes conversion of light into electricity more efficient.
