Answer:
1. True
Explanation:
From a certain depth, most of the carbonates dissolve, but the shells of the most resistant foraminifera do not. It is the LISOCLINE
.
From a certain depth, carbonates and microfossils dissolve completely beyond lysocylin. It is the CALCITE COMPENSATION LEVEL (CCD)
.
In areas deeper than the CCD, only clay or siliceous sediments are deposited and carbonates and carbonated fossils are absent
.
Lysocline and CCD vary in depth today in each ocean, being greater in the tropical belt (up to 5000 m)
. The CCD for the same latitude has varied throughout geological time
.
Due to the huge size of the country, Australia has serveral different climate zones. The northern section of Australia has a more tropical influenced climate, hot and humid in the summer, and quite warm and dry in the winter, while the southern parts are cooler with mild summers and cool, sometimes rainy winters. The main vegetation types in Australia (in simplified terms) are forest, rainforest, grassland and desert. Different types of trees, shrubs and grasses grow within each of these vegetation types and are specially adapted to the soil, rainfall and temperature in each area.
