A peek inside

Rudy tugged on his bright cap and stomped into the garden in muddy boots. Today he would dig like a real geologist and study what hid under the flower beds. "Hello, earth!" he said cheerfully. He lifted his small spade and made the first soft scrape. Learning about rocks and soil started right here, one careful scoop at a time.

Rudy dug down and found dark, crumbly topsoil full of tiny bits of old leaves. Topsoil is the upper layer where many plants grow their roots. It feels soft and smells earthy after rain. "This soil feeds the flowers," Rudy whispered. He rubbed a pinch between his fingers and watched it fall loosely back into the hole.

Deeper beside the path, Rudy found pale sandy soil that slipped through his hands. Sandy soil has large grains and does not hold water for long. Water drains quickly between the grains, so plants there need careful watering. "You feel gritty!" Rudy laughed. He poured a little water and watched it vanish almost at once into the sand.

Near the vegetable patch, the soil stuck to Rudy's boots in heavy clumps. This was clay soil, made of very fine particles packed tightly together. Clay holds water well and can feel smooth when wet, almost like soft modelling dough. "You are sticky!" said Rudy, peeling a lump free. He shaped a small ball and left it to dry in the sun.

In the middle of the flower bed, Rudy discovered rich brown loam. Loam is a balanced mix of sand, clay, and tiny bits of decayed plants called humus. Many gardeners love loam because it holds some water yet still lets roots breathe. "You feel just right," Rudy said with a grin. He patted the loam gently back around a daisy.

Under a stone path, Rudy found flat layered rock that looked stacked like thin pages. This was sedimentary rock, formed when bits of sand, mud, or shells settled and pressed together over a very long time. You can often see stripes or layers in it. "You tell a slow story," Rudy murmured. He traced one smooth layer with his muddy fingertip.

Beside the rockery sat a hard speckled stone that felt cool and solid. Rudy learned it was igneous rock, born when hot melted rock cooled and turned hard. Some igneous rocks cool underground; others cool above ground after a volcano. "You were once fiery!" he said in wonder. Tiny crystals sparkled faintly when he tilted the stone toward the light.
