Chemical weathering occurs faster in warm tropical climates, although it happens in cold climates as well, describe some conditions in antarctica that could lead to chemical weathering

Conditions in which it will lead to chemical weathering are the following;

-          Oxidation – formation of oxides when a rock reacts with elements oxygen and water changing into different color.

-          Dissolving in acid – carbonic acid is formed when carbon dioxide is dissolve n water, creating karst topography in creating sink holes and caves.

-          Hydrolysis – chemical weathering which is caused with the element water, it turns clay minerals.

-          Water absorption – rocks are put into stress making them vulnerable and expand.

-          Hydration – removal of water in the rocks.

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.

That is false the sun’s core does not fusion
