#3 Sedimentary Rocks1. Go back to the main page and click “Sedimentary Rocks”

2. The three key vocabulary terms are:

a. _______________________

b. _______________________

c. _______________________


a. It's hard to believe, but ___________________ rocks like this sandstone formation in Glen Canyon, Utah, are made from tiny bits of ___________________.

b. Pieces of ___________________, ___________________, and ___________________ are all sediment. Sediment is created through weathering and erosion. Wind, water, and ice all weather rocks. As the rocks ___________________, pieces of sediment are created.

c. The sediment settles, or ___________________, in one place and piles up. Just like the Nockamixon Cliffs that run along the Delaware River in Pennsylvania.

d. Layer upon layer of sediment settle until the ___________________ of the sediment squeezes the sediment ___________________. Minerals that get mixed into the sediment help ___________________ the sediment together like in close-up of the Bright Angel Shale Formation.

e. When ___________________ and other matter fall between the layers of sediment, they become part of the rock. Sedimentary rock made up mostly of shell fragments is called ___________________. The Watchtowers of Castillo de San Marcos is made of coquina.

2. The four key vocabulary terms are:

a. _______________________

b. _______________________

c. _______________________

d. _______________________


a. Deep under Earth's surface, rocks are under ___________________ from all the rocks above them. All this heat and pressure transforms them into ___________________ rock. This slate was formed from shale, a sedimentary rock.

b. ___________________ means "change in form." That's where the word metamorphic comes from. The heat and pressure has changed the form of the rock. The result is a ___________________ rock.

7

c. Heat and pressure turns _________________, a sedimentary rock, into __________________, a metamorphic rock.

d. Granite, an ___________________rock, transforms into gneiss, another type of ___________________rock

f. Metamorphic rocks make up a large part of Earth's ___________________. Since the rock is so tightly packed, it isn't porous. That means it's hard for water to get through, which makes it very useful in ___________________.

Wind, rain, and other weather turn lava from volcanoes into metamorphic rock

3. Which kind of rock can be turned into gneiss?a. Marbleb. Shalec. Magmad. granite
