The roots of the tree hold it tight to the Earth which is the source of its nourishment
In this line from Joyce Kilmer's poem "Trees," he describes the tree's roots as being deeply connected to the earth, drawing nourishment like a hungry mouth against the earth's fertile and life-giving surface. This imagery highlights the profound and intimate relationship between the tree and the earth.
Hot, slowly flowing rock comprises the asthenosphere, which is part of the mantle.

These streams are called Currents. An example would be The Gulf Stream.
These are glaciers.
Runoff is the water flowing downhill across the surface of the Earth.
That would be the sun. It is a star and provides the light and warmth required to support life and flowing water.
The plates are pushing against eachother.
When the molten rock is actually flowing on the earth, it is called lava. When it is contained, such as in a volcano, it is called magma.
Volcanoes are caused by the rising of magma in the earths mantle and earthquakes are caused by the colliding of the earths tectonic plates against one another.

Rivers, wind, and ice are three ways. Rivers create landforms by flowing deeper and deeper into the earth. Ice flowing downhill carves valleys into a mountain range. Soil erosion is formed by wind and water.
