Important weather phenomena occur mostly in the a. thermosphere b. stratosphere c. mesosphere d. troposphere

The answer is:

Troposphere

Here is more about your question:

The Earth's atmosphere is divided into layers and the troposphere is the first layer. This layer is where we live in. This layer also has the most moisture among all the layers and this is why most clouds and weather occur in this layer. The other layers have very little moisture.

The features of the mesosphere would be the ice crystals that form there because it is so cold. The ice crystals help protect the Earth from meteors and other space junk. The stratosphere is the layer that contains our ozone layer. The thermosphere is the outermost layer, which contains the ionosphere and the exosphere.

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
