Jawab:
1. Dampak jika atmosfer di bumi didominasi oleh karbondioksida:
- Konsentrasi CO2 meningkat, suhu meningkat
- Perubahan suhu lautan, perubahan arus laut
- Gletser mencair
- Permukaan air laut naik, banjir besar mengancam daerah rendah, tenggelamnya daratan
- Menipis dan mencairnya es kutub
- Cuaca berubah secara drastis
- Danau Mengering di Afrika
- Danau membeku lebih lambat di Belahan Bumi Utara
- Musim dingin berakhir lebih cepat
- Musim semi datang lebih cepat, musim gugur datang Iebih lambat
- Es di gunung mencair

2. Asal muasal air di bumi:
- Pendinginan Bumi purba hingga ke titik ketika komponen volatil yang terlepas ke atmosfer mencapai tekanan tertentu yang memungkinkan penstabilan dan pemertahanan air.
- Komet , objek trans-Neptunus , atau meteorit ( protoplanet) yang kaya akan air menubruk Bumi. Pengukuran rasio isotop hidrogen deuterium dan
protium menunjukkan peran asteroid karena kemiripannya dengan persentase ketidakmurnian dalam kondrit yang kaya akan karbon di samudra Bumi, sementara pengukuran terhadap konsentrasi isotop di komet dan objek trans-Neptunus tidak terlalu mirip dengan yang di Bumi.
- Secara biokimia melalui mineralisasi dan
fotosintesis
- Perembesan air yang disimpan di mineral hidrat di bebatuan Bumi secara perlahan.
- Fotolisis : radiasi dapat mengurai ikatan kimia di permukaan.

3. Hal-hal yang terjadi jika bumi berhenti berputar:
1. Kekacauan Navigasi Pesawat
2. Pertambahan durasi hari
3. Bumi Menjadi Tidak Bulat Sempurna
4. Banjir dan kekeringan
5. Naiknya Tekanan Udara
6. Terganggunya Kehidupan Flora & Fauna
7. Aktivitas Geologi Bertambah Ekstrim
8. Melemahnya Medan Magnet Bumi
9. 1 Hari = 13 Hari Normal
10. Munculnya Benua Baru
11. Cuaca Menjadi Sangat Ekstrim.
12. Satu Hari Sama Dengan Setahun
13. Hancurnya Populasi Manusia
