The country among the choices which has about 20 active volcanoes is the Philippines. The PHIVOLCS which is the Philippine national institution dedicated to studies on volcanoes have identified at least 23 volcanoes as active with 21 of them having historical eruptions.
Definition of erosion (according to National Geographic): “Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.”
1. Describe the features that water erosion produces in your images (mountains, canyons, deserts, etc?) What do they have in COMMON?
Mountains: Water erosion would create a waterway around the mountains.
Canyons: Water erosion would create more area between the canyons.
Deserts: Water erosion would generally change the desert’s landscape by making the hills more downslope.
What they have in common: They all create changes to the landscape of different areas.
2. You can see water erosion even when you do not see water. How is this possible? Be clear!
This is possible by rain?
- I’m not exactly sure about this question.
C) mountains
I just did this and it is the right answer
Layers of the soil are called horizons. Here are the horizons:
- Humus
- Topsoil
- Subsoil
- Fragmented rock
- Bedrock
Once a soil has developed, it forms layers called horizons. Beneath a surface layer of a plant remains, the topsoil is rich in decomposed plants and animal matter. The subsoil is mainly mineral particles, with much less organic material. The fragmented rock/bedrock is primarily small stones, and beneath it lies all bedrock.
Hope this answer helps you!
Yes yes yes yes yes yes yes.
