Answer:

Ice cores are cylinders of ice drilled from ice sheets/glaciers. ice cores tell scientists about temperature, volcanic activity, atmospheric composition, precipitation, and wind patterns.

Explanation:

the thickness of each layer in the core allow scientists to determine how much snow fell in the area during a particular year. the layers are formed by layers of different types of snow. During the summer, when it is light for 24 hours, the snow on the top layer changes texture. When winter arrives, it turns dark and cold again and more snow falls on top of the summer snow, creating distinct layers.

Hope this helps!

If you were planting a vegetable garden, what should you consider for the time of planting?
zvonat [6]

When planting vegetables it is very important to know the climate of the area, its usual patterns, and how will that affect the growth and development of the crops. The soil quality too is very important, as it is the basis for the development of the root-stock of the crops.

If we have a temperate type of climate, than we have four different seasons, meaning different weather patterns throughout the year. We can take onions, radish, and peppers as vegetables of choice. The onions can be planted in mid-autumn, as they will need more moisture, and they are resilient to low temperatures, thus will not have problems in the winter, and in the spring they will already have the basis so will grow quickly and be larger. The radish can be planet in late winter or early spring, in a period when there is more precipitation. It is not a vegetable that likes high temperatures, so with its quick development, it will be able to develop the tuber by late spring. The peppers can not sustain low temperatures, so they should be planted in late spring. They also like warm weather and lot of water, so it will be needed to water them a lot in the hot and dry period. They will manage to develop and produce the vegetables by the end of the summer, thus not getting damaged by the cold nights in the autumn.
