How would you get sedimentary rock and metamorphic rock from the lava after volcano has erupted?

What are 4 land features that glaciers cause from their movement?

Thanks for any help!

To understand how to obtain sedimentary rock and metamorphic rock from lava after a volcanic eruption, here's a step-by-step explanation:

1. After the eruption, allow the lava to cool and solidify. This process may take a considerable amount of time, as the lava needs to reach room temperature or colder.

2. As the lava cools, it undergoes a process called solidification, where it transforms from a molten state into a solid state. This solidified lava is known as volcanic or igneous rock.

3. To obtain sedimentary rock, the volcanic rock needs to undergo weathering and erosion, which occur over an extended period of time. Weathering refers to the breakdown of rocks into smaller fragments due to various natural processes like wind, water, and temperature changes. Erosion involves the transportation and deposition of these fragmented rocks by agents such as water, wind, or ice.

4. The fragmented volcanic rock fragments, known as sediment, are carried away by erosional agents. Over time, these sediments may accumulate in a depositional environment such as lakes, rivers, or ocean basins.

5. The weight of the accumulated sediments compresses the lower layers, leading to compaction. This, combined with the presence of minerals like silica or calcium carbonate, facilitates the process of lithification, where sediment turns into sedimentary rock.

To obtain metamorphic rock from lava, the volcanic rock needs to undergo metamorphism, a process caused by intense heat and pressure. This can occur due to tectonic forces when volcanic rocks are subjected to the Earth's internal heat and pressure.

Now, let's move on to the four land features caused by the movement of glaciers:

1. U-shaped Valleys: Glacier movement carves out valleys in the shape of a "U." The ice erodes the surrounding rock as it advances, creating a broad and steep-walled valley.

2. Moraines: Glacial moraines are landforms made up of sediment and debris transported or deposited by a glacier. These can be lateral moraines (along the sides of a glacier), medial moraines (formed when two glaciers merge), or terminal moraines (deposited at the farthest point of advancement).

3. Cirques: Cirques are amphitheater-like hollows found at the head or upper end of a glacial valley. They are formed when glaciers erode rock through plucking and abrasion.

4. Glacial Erratics: Glacial erratics are large boulders that are carried and deposited by glaciers in areas far from their original source rocks. Glaciers transport these erratics and then leave them behind as they melt, creating noticeable features on the landscape.

I hope this explanation helps! Let me know if you have any further questions.
