Answer:
Japan's population is shrinking and aging.
Explanation:
1. The carbon in a buried peat bed has about 6% of the C-14 of modern shells. When the plants that now form the buried
peat were alive, they absorbed C-14 and probably had about the same amount of C-14 as modern shells, so about 94% of
the peat's original C-14 has decayed. What is a reasonable initial estimate of the age of the peat bed? Explain,
2. In sampling the peat bed, you must be careful to avoid any young plant roots or old limestone. Why?
Based on the percentage that has decayed of the peat's original C-14, a reasonable estimate of the age of the peat bed is 22,880 years.
We should be careful to avoid old limestone because it contains carbon that will help in finding the age of the peat bed sample. Same goes for the young plant roots.
What is an estimate of the age of the peat bed?This can be found as:
= Half life of C-14 x Number of half lives that have passed
Number of half lives that have passed based on 6% being left of the orginal sample will be 4 half lives.
Estimate of age:
= 5,720 x 4
= 22,880 years.

cold currents tend to decrease the temparature of coastal regions
Answer:
Warm and cold ocean currents can affect the climate of coastal regions, but only when local winds blow in from the sea. Warm currents heat the air over the ocean and bring higher temperatures over land. Cold currents can lower air temperatures and can bring colder temperatures over land.

list the sedimentary rock that formed during the mesozoic era in ethiopia and the horn?
Answer: sandstone, limestone, shale, marls and evaporites (Adigrat Sandstone, Antalo Limestone, Amba Aradam Formation)
Explanation:
Sandstone, limestone, shale, marls, and evaporites (Adiabat Sandstone, Anatol Limestone) are the sedimentary rocks formed during the Mesozoic era in Ethiopia and the Horn.
What are Sedimentary rocks?Sedimentary rocks are one of the types of rock formed by the deposition, sedimentation, and lithification of sediments over a long period of time, and these rocks is found in layers and contain fossil fuels.
Rocks formed by the East African Orogeny 880 to 550 million years ago make up the oldest geological units in Ethiopia on the African continent. The orogeny caused the closure of the ancient Mozambique Ocean in the Indian ocean . Rocks of Ethiopia formed concurrently with the Mozambique Belt and the Arabian-Nubian Shield, forming a large north-south mountain chain called the Trans Gondwana Super-mountain.
Erosion of the Gondwana super mountain mountain may have played a role in triggering the Cambrian explosion. Sedimentary rocks of Ordovician age cover this surface, making it largely an unconformity.
Hence, sandstone, limestone, shale, marls and evaporites (Adiabat Sandstone, Anatol Limestone) are the sedimentary rocks formed during the Mesozoic era in Ethiopia and the Horn.
