7th Quarter 2 Midterm

What are the three main types of rocks?

• Volcanic, crystalline, and organic

• Igneous, sedimentary, and metamorphic

• Magma, lava, and tectonic

• Granite, limestone, and shale

Explain the difference between igneous, sedimentary, and metamorphic rocks.

• Igneous rocks are formed from cooling and solidification of magma or lava, sedimentary rocks are formed from accumulation and compression of sediments, and metamorphic rocks are formed from alteration of existing rock through heat, pressure, or chemical processes.

• Igneous rocks are formed from the accumulation and compression of sediments

• Sedimentary rocks are formed from alteration of existing rock through heat, pressure, or chemical processes

• Metamorphic rocks are formed from cooling and solidification of magma or lava

How are tectonic plates related to earthquakes and volcanic activity?

• Tectonic plates cause volcanic activity, but not earthquakes

• Tectonic plates only cause earthquakes, not volcanic activity

• Tectonic plates interact at their boundaries, leading to earthquakes and volcanic activity.

• Tectonic plates have no relation to earthquakes and volcanic activity

What is the process of heat transfer through direct contact called?

• conduction

• reflection

• radiation

• absorption

Describe the concept of convection as a form of heat transfer.

• Transfer of heat through the movement of a fluid

• Transfer of heat through the movement of solid

• Transfer of heat through the movement of light

• Transfer of heat through the movement of sound waves

What is the geologic time scale and why is it important in understanding Earth's history?

• A type of musical scale used in geology to measure seismic activity

• A system of chronological dating that relates geological strata to time, and it helps scientists to organize and interpret the history of the Earth.

• A scale used to measure the height of geological formations

• A scale that measures the temperature of the Earth's core

What are the properties of a transverse wave?

• Does not oscillate at all

• Moves in a circular motion

• Oscillates perpendicular to the direction of energy transfer and has crests and troughs

• Moves in the same direction as energy transfer and has peaks and valleys

Explain the difference between a longitudinal wave and a transverse wave.

• Longitudinal waves have particles that vibrate perpendicular to the direction of the wave, while transverse waves have particles that vibrate parallel to the direction of the wave.

• Longitudinal waves have particles that do not vibrate, while transverse waves have particles that vibrate perpendicular to the direction of the wave.

• Longitudinal waves have particles that vibrate parallel to the direction of the wave, while transverse waves have particles that vibrate perpendicular to the direction of the wave.

• Longitudinal waves have particles that vibrate perpendicular to the direction of the wave, while transverse waves have particles that do not vibrate.

How do waves transfer energy from one place to another?

• Through the movement of clouds

• Through the vibration of particles in a medium or through electromagnetic radiation

• Through the rotation of the Earth

• Through the growth of plants

This type of thermal energy transfer can take place in gases only.

• conduction

• convection

• radiation
