Question

ordering question
click and drag on elements in order
place the steps involved in the formation of glaciers and ice caps in order, starting with the first step at the top of the list.

instructions
gravity causes the mass of ice and snow to flow downhill like a slow-moving river.
the mass of ice and snow gets very heavy.
layers of un-melted snow pile up.
the top layers of snow press down on the lower layers, turning them to ice.

Explanation:

To determine the order, we analyze the glacier formation process:

1. First, snow accumulates: "Layers of un - melted snow pile up."
2. Then, the weight of the top snow compresses the lower layers into ice: "The top layers of snow press down on the lower layers, turning them to ice."
3. Next, the ice - snow mass becomes heavy: "The mass of ice and snow gets very heavy."
4. Finally, gravity makes it flow: "Gravity causes the mass of ice and snow to flow downhill like a slow - moving river."

Answer:

1. Layers of un - melted snow pile up.
2. The top layers of snow press down on the lower layers, turning them to ice.
3. The mass of ice and snow gets very heavy.
4. Gravity causes the mass of ice and snow to flow downhill like a slow - moving river.
