melting and cooling
The mesozoic era is known as the age of the
reptiles
A mineral's hardness describes its
resistance to scratching
The idea that present day geologic processes can be used to understand the past is referred to as
uniformitarianism

Which feature in minerals is the most obvious, but not reliable in identification?
Color
Which type of stress is pushing things together?
Compressional
Volcanoes do NOT form at which type of convergent plate boundary?
Continental-continental convergent boundaries
A scientist is conducting a study to determine how well a new medication treats ear infections. The scientist tells the participants to put 10 drops in their infected ear each day. After two weeks, all participants' ear infections had healed. What changes to the design of this study would most improve the ability to test if the new medication effectively treats ear infections?
Create a second group of participants with ear infections who do not use any ear drops
What is the principle of original horizontality?
Each new layer of sediment is laid down nearly horizontally over older sediment

When large areas of forest are removed so land can be converted for other uses, such as farming, what occurs?
Increased erosion
What is a major concern about the overuse of antibiotics?
It can lead to antibiotic resistance bacteria

What type of rock is formed due to high temperatures and pressure?
Metamorphic rock
What is the metric basic unit to measure length?
