Answer:
Smoke and fumes
Explanation:
Smoke and fumes contain carbon monoxide, carbon dioxide and carbon particles. These are produced from industries which burn coal and petroleum fuels and also from motor vehicles exhaust. Carbon dioxide prevents layers of warm air from escaping into the upper atmosphere causing greenhouse effect that leads to global warming. On a global scale, this may bring about melting of the polar ice caps thus raising the level of oceans hence flooding of lowland areas.
Weathering and erosion ( they caused water and wind action)
Indonesian: tanaman sangat penting. mereka membantu mempertahankan kehidupan hewan dan manusia. tanaman memberi makan kita. tanaman memberi pekerjaan pada petani karena petani menjual dan memakan tanaman (dan hewan) agar tetap hidup. bagaimana hewan-hewan itu hidup? mereka makan tanaman.
jika tanaman entah bagaimana menghilang secara misterius. semuanya akan berantakan, hewan akan mati, yang akan membuat manusia mati kecuali zat lain dibuat untuk menjaga hewan tetap hidup. tanaman penting karena ini.
english: plants are very important. they help sustain life of animals and humans. plants feed us. plants give farmers work because farmers sell and eat plants (and animals) to stay alive. how do those animals live? they eat plants.
if plants were to mysteriously disapear somehow. everything would fall apart, animals would die, which would make humans die unless another substance is made to keep animals alive. plants are important because of this.
