Why earthworm come out on ground in rainy season?

Earthworms come out on the ground during rainy seasons to avoid suffocating in waterlogged soil. They need oxygen to survive, and the rain saturates the soil, pushing them to the surface where they can breathe. Additionally, the moisture also helps them move more easily through the soil to find food and mates.

Where does delta's soil come from?

Delta soil primarily comes from sediment deposited by the Mississippi River. Over millions of years, the river has carried and deposited fine-grained sediments, creating the fertile soil that characterizes delta regions like the Mississippi Delta. Additionally, natural processes like flooding and erosion contribute to the formation and replenishment of the soil in delta areas.


Does the soil in a delta come from volcanoes?

No, the soil in a delta does not primarily come from volcanoes. Deltas are formed from the accumulation of sediment carried by rivers and deposited as they flow into a body of water, such as an ocean or lake. The soil in a delta is typically a mixture of silt, sand, and clay particles eroded from the land upstream.


Where do the essential elements in the soil come from?

Essential elements in the soil primarily come from the weathering of rocks and minerals. As rocks break down over time, they release nutrients such as phosphorus, potassium, calcium, and magnesium into the soil. These nutrients are then available for plant uptake and growth. Additionally, decomposing organic matter and biological activity also contribute to the cycling of essential elements in the soil.
