1148 - How does the change in landscape caused by flowing water and biological activity differ.

Let's break it down in a simple way:

Flowing Water: When water flows (like in rivers or streams), it can change the landscape in these ways:

• It carries rocks and soil away, creating a new path or deeper channels.
• It can create holes or pools by eroding the surrounding area.
• It can deposit rocks and soil in a different place, creating new landforms or changing the shape of the existing ones.

Biological Activity: Biological activity, like plants and animals, can also change the landscape in these ways:

• Roots of plants can break rocks and hold soil together, preventing erosion.
• Animals can dig burrows or tunnels that create new pathways or holes in the ground.
• When plants and animals die, they leave behind organic matter that can fertilize the soil and help new plants grow.

The main difference is that flowing water wears down the landscape (erosion), while biological activity can both wear it down and build it up (by creating new soil or changing the ground shape).
