A

Granite

21
Q

Which of the following processes occurs when water seeps into cracks in a rock, freezes, and breaks the rock apart?

A

Physical weathering

22
Q

The material ejected from a shield volcano is mostly:

A

Non-viscous Lava

23
Q

Which of the following is not true regarding global warming and climate change?

A

Temperatures around the world are universally increasing

24
Q

Which of the following statements most accurately describes an igneous rock?

A

a light, very porous rock with visible holes, grains that are too small to see, and no fossils

25
Q

Why is material in the asthenosphere, the upper mantle, able to flow?

A

The asthenosphere is a very hot solid that can slowly circulate.

26
Q

Which of the following best describes the lithosphere?

A

A zone of rigid rock on Earth’s surface that includes the crust and the solid upper part of the mantle.

27
Q

Which of the following best explains how metamorphic rocks are formed?

A

Rocks are changed by heat, with or without high pressure, deep inside the Earth.

28
Q

Which of the following would be the most appropriate occasion for a scientist to use carbon dating?

A

to determine the age of a newly-discovered fossil

29
Q

Which of the following statements most likely describes a metamorphic rock?

A

a rock with wavy bands of minerals that is very hard and has visible crystals

30
Q

Which of the following volcanoes is large and explosive, is built with alternating layers of light-colored rock and ash, and forms near a subduction zone?

A

stratovolcano

31
Q

An increase in carbon dioxide (CO2) emissions on Earth is thought to be responsible for which of the following?

A

an increase in Earth’s average temperatures

32
Q

Which of the following volcanoes is small and produces light, viscous, granitic lava around the vent of a larger volcano?

A

Lava dome

33
Q

Which of the following human activities is least likely to alter the environment?

A

Over watering the lawn

34
Q

Which type of rock is formed when magma cools very slowly?

A

Intrusive igneous rock

35
Q

The earth is divided into four distinct layers. Which layer is composed of very hot, liquid material?

A

Outer core

36
Q

There are three different types of rocks: sedimentary, igneous, and metamorphic. Over time, each of these rock types can be transformed into one of the other rock types. For example, if limestone which is a type of sedimentary rock is exposed to high heat, it can be transformed into marble, which is a metamorphic rock.

This process of rocks changing from one form into another form is typically referred to as:

A

Rock cycle

37
Q

Which of the following is the name for the point inside the earth where an earthquake originates?

A

Focus
