Deficiency of calcium in plants causes reduced internode length and crinkled leaves.
Initial signs of calcium Deficiency include localized tissue necrosis that stunts plant growth and causes young leaves to curl or have necrotic leaf margins, and terminal buds and root tips to eventually die. New growth and tissues that are expanding quickly on the plant are typically the first to be harmed.
- These include boron, copper, iron, manganese, molybdenum and zinc. Most nutrient deficiencies are caused by a lack of nutrient content in the growing medium or nutrient solution
- Plants require calcium in order to develop new growth points and root tips. Symptoms of a deficiency include decreased growth in new leaf, buds, and roots. Younger leaves curl downward and develop tip burn, which is the browning of the leaf edges and tips.

Answer:
the plates of the lithosphere move (or float) on this hot, malleable s<u>emi liquid zone</u> in the upper mantle, directly underneath the <u>lithosphere</u>
Explanation:
- Lithosphere is the outermost layer of earth surface which contains crust and uppermost solid mantle.
- Tectonic plates are subdivision of lithosphere where tectonic activities take place. Tectonic activities often occur in Lithosphere which affects the structure of this layer by changing the landscape on earth surface.
- The Lithosphere is the layer where soil forming process takes place. The lithosphere influences temperature difference on earth when it reacts with the other layers called atmosphere, hydrosphere and cryosphere.
