1: The Carboniferous Period lasted from:
1.2 billion to 1.095 billion years ago
495 million to 425 million years ago
359 million to 299 million years ago
140 million to 65 million years ago
2: The Carboniferous is often divided into two other periods. The earliest (oldest) one is called the

3: The later, second period is called the

4: The name Carboniferous is from the Latin word for
coal
5: The large coal deposits of the Carboniferous were formed mainly because of two key factors. They are
Large flowering plants and high oxygen levels
Higher temperatures and greenhouse gases
A mass extinction event and higher sea levels
Bark-bearing trees and lower sea levels
6: Hydrocarbons are the main ingredient in oil.
True
False
7: Geologists often refer to the temperature range in which oil forms as an __________________ —below the minimum temperature oil remains trapped in the form of kerogen, and above the maximum temperature the oil is converted to natural gas through the process of thermal cracking.
Oil Threshold
Kerogen Transition Point
Cracking Point
Oil Window
8: Petroleum can migrate hundreds of kilometers horizontally, and even short distances downward, before becoming trapped in an _______________.
Oil Bunker
Oil Trap
Oil Reservoir
Oil Basin
9: Hydraulic Fracturing involves the high-pressure injection of 'fracking fluid' (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely
True
False
10: Synapsids ('fused arch') are a group of animals that includes mammals and everything more closely related to mammals than to other living amniotes. Primitive synapsids are usually called pelycosaurs; more advanced mammal-like ones are called ___________
Chronosids
Therapsids
Omnisids
Lapidosids
11: Synapsids are distinguished from other amniotes by having a single opening (temporal fenestra) in their skull behind each eye, which developed in the ancestral synapsid about 324 million years ago (mya) during the late Carboniferous Period.
True
False
12: The therapsids included the cynodonts, the group that gave rise to mammals in the Late Triassic around 225 million years ago.
Mammaladonts
Autodonts
Ergopsids
Cynodonts
13: The geologic period immediately following the Carboniferous is the
