Ricardo has an igneous rock in his rock collection. Where did this rock most likely form?
What is a coral reef or an island.

A boundary where two tectonic plates come together, or collide, is called a
What is a divergent boundary.
200
To find the absolute age of the fossil shells, the geologist would use
What are radioactive isotopes.
200
Most earthquakes and volcanoes occur in areas of the Pacific Ocean called "The Ring of Fire." What is the main reason for this?
What is plate boundaries lie here.
300
Cleavage of a mineral is related to a mineral's
What is crystal structure.
300
How do active volcanoes located on islands create more land area on these islands?
What is magma cools and forms igneous rock.
300
In an undisturbed layer of rock, older rocks lie at the bottom and younger rocks lie at the top.
What is uniformitarianism?
300
Fossils of a particular animal species have been found in both southern Africa and South America but nowhere else. How can this be?
What is the continents were once joined.

Sedimentary rocks are not found on the Moon because
What is there is no weathering on the moon.

Cleavage of a mineral is related to a mineral's
What is crystalline structure.

Barrier islands are low and narrow sandy islands that form a rim offshore from a coastline. These islands protect inland shores from the surf, especially during storms. These islands are becoming increasingly developed because people want to live by the open ocean, yet the islands themselves are not permanent. Why aren't the islands permanent?
What are erosion and deposition?
400
This is an example of what type of scale? Scale Felt Intensity 2 Lamps swing 4 Dishes and windows break 6 Chairs, beds, table move 8 Walls collapse 10 Roads crack, landslides 12 Total destruction
What is a Mercalli Scale?

Limestone is a sedimentary rock found in South Georgia and North Florida. Limestone is easily weathered and eroded because the main mineral found in limestone reacts acid rain and ground water. What type of mineral likely makes up limestone?
What is calcite.
500
The surfaces of old concrete statues are often covered with small holes or pits. Which of these MOST LIKELY causes these holes or pits?
What is acid precipitation.
500
What landform is created when two continental plates spread apart?
What is a rift valley?
500
A fossil of an ocean fish was found in a rock outcrop on a mountain. This probably means that
What is the area was once below sea level.
500
What is the relationship between earthquakes and volcanoes?
What is earthquakes can cause volcanoes to erupt, and volcanoes can cause earthquakes to occur.
