Please help with some science questions?
13. How are folds categorized?
A) By the relative ages of the rocks in the fold
B) By the color of each of the rocks in the fold
C) By the density of the rocks contained in the fold
D) By the hardness of the rocks in the fold

14. What type of fold has the youngest rock layer in the center of the fold?
A) Anticline
B) Monocline
C) Strike-slip
D) Syncline

15. How does rock move at a strike-slip fault?
A) Rock on either side of the fault moves toward each other
B) Rock on either side of the fault plane slides horizontally
C) The hanging wall is pushed over the footwall
D) The footwall is pushed up over the hanging wall

16. A reverse fault __________.
A) is formed when the hanging wall moves upward relative to the footwall
B) is formed when the hanging wall moves downward relative to the footwall
C) is formed when the footwall and hanging wall collide directly into each other
D) is formed when rock on both sides of the fault plane slides horizontally

17. At convergent boundaries, mountains can form when __________.
A) oceanic and continental lithosphere separate
B) oceanic and continental lithosphere collides
C) sea water engulfs the oceanic lithosphere
D) wind blows oceanic lithosphere into mountains

18. Pieces of crust that may break off and form mountains when oceanic lithosphere subducts are called __________.
A) asthenosphere
B) terranes
C) subductions
D) anticlines

19. A collision between two plates consisting of oceanic crust can form __________.
A) volcanic mountains
B) hurricanes
C) strike-slip faults
D) None of the above

20. The Himalaya Mountains formed when __________.
A) North America collided with Antarctica
B) South America collided with Europe
C) Australia collided with Canada
D) the Indian plate collided with Eurasia

21. What type of mountain is formed when magma rises through Earth’s crust and pushes up the rock layers above the magma?
A) Folded mountain
B) Plateau
C) Dome mountain
D) Graben

22. How do folded mountains form?
A) By tectonic movements squeezing rock layers together into folds
B) By magma rising through Earth’s crust and pushing up rock layers
C) By stretching Earth’s crust and breaking into large blocks
D) By magma erupting onto Earth’s surface

23. Because magma rises to Earth’s surface at mid-ocean ridges, what types of mountains are commonly found there?
A) Strike-slip mountains
B) Volcanic mountains
C) Fault-block mountains
D) Plateaus

24. How were the Hawaiian Islands formed?
A) Through convergent boundaries at mid-ocean ridges
B) By tectonic movements squeezing rock layers together into folds
C) By magma erupting and causing volcanic mountains to form above sea level
D) By continents colliding with each other millions of years ago

25. How did the volcanoes of the Andes Mountains form?
A) From the subduction of the oceanic crust under the continental crust
B) From oceanic crusts coming together at convergent boundaries
C) From Earth’s crust breaking into large blocks
D) None of the above
