Patterns of Change

Nature's patterns are visible in some rocks as small pebbles and in wonders as vast as the Grand Canyon. What is the meaning of natures patterns are visible ?

• It means that the designs and formations created by nature can be observed in different sizes and contexts.
• It refers to the random arrangement of rocks and pebbles.
• It suggests that patterns in nature are man-made and not natural.
• It indicates that nature's patterns are only found in large landscapes.

How are Igneous Rocks formed ?

• Igneous rocks are formed from the erosion of sediment.
• Igneous rocks are formed from the cooling and solidification of magma or lava.
• Igneous rocks are formed through the melting of existing rocks.
• Igneous rocks are created by the compression of organic materials.

Igneous rocks do not stay the same forever. Water and wind erode them, carrying away particles of broken rock and depositing them elsewhere . What is a good definition of erode ?

• To erode means to create new rock formations through volcanic activity.
• To erode means to increase the size of a rock by adding material.
• To erode means to solidify and harden existing rocks.

What do we call persons who study rocks ?

• Geologists
• Biologists
• Meteorologists
• Astronomers

As the magna slowly cools , it will turn back into igneous rock . The repitition of this process is called rock cycle . The rock cycle is a pattern - a pattern of change . What is a rock cycle ?

• The rock cycle is a pattern of change in which rocks transform between igneous, sedimentary, and metamorphic forms.
• The rock cycle is a process where rocks are formed from water.
• The rock cycle only involves the formation of sedimentary rocks.
• The rock cycle is a linear process that does not involve any transformations.
