Hello parents and students!

Today’s essay is about geology! We have been learning about the rock cycle, and I included a helpful outline here for your essay.

Paragraph 1 – Introduction

-3 kinds of rocks

-Igneous, Sedimentary, Metamorphic

-Introduce the rock cycle

Paragraph 2 – Igneous Rocks

-Formed when lava cools

-Found near volcanoes

-Were once lava so they can contain bubbles

Paragraph 3 – Sedimentary Rocks

-Formed underneath water and land

-Caused when sediment gets pushed down into the earth

-Formed under enormous pressure

-Can be caused when weather moves sediment from place to place

Paragraph 4 – Metamorphic Rocks

-When sedimentary rocks are pushed down far enough, they become metamorphic

-Meta. rocks contain many wavy lines that make them distinct

-They can only be formed under intense heat

-They are found close to lava

-After metamorphic rock melts down, it becomes lava, re-starting the rock cycle

Paragraph 5 – The Rock Cycle

Igneous Rocks become sedimentary rocks. Sedimentary rocks get pushed down into the earth and become metamorphic rocks. Metamorphic rocks become lava and when the lava hardens, the rock becomes an igneous rock again.
