Which is an example of evidence that changes in the biosphere affect other Earth systems?(1 point) Responses Increasing ozone increases weathering. Increasing ozone increases weathering. Increasing carbon dioxide concentration increases global warming. Increasing carbon dioxide concentration increases global warming. Coral reef destruction reduces the protection of the shoreline. Coral reef destruction reduces the protection of the shoreline. Increased UV protection increases animal evolution.
Coral reef destruction reduces the protection of the shoreline.
Use the image to answer the question. Which statement makes a correct observation of the image above? (1 point) Responses Humans are the only organisms whose fossils were found on both the African and South American continents. Humans are the only organisms whose fossils were found on both the African and South American continents. The same fossils were always found in South American and Africa. The only difference is that horses were found in Africa and not South America. The same fossils were always found in South American and Africa. The only difference is that horses were found in Africa and not South America. Until about 250 million years ago, fossils of the same organisms were found in both South America and Africa. After this, mostly different organisms were found. Until about 250 million years ago, fossils of the same organisms were found in both South America and Africa. After this, mostly different organisms were found. No fossils of organisms were from before 250 million years ago. The Mesosaurus fossil from 250 million years ago was found in both Africa and South America.
Until about 250 million years ago, fossils of the same organisms were found in both South America and Africa. After this, mostly different organisms were found.
Use the image to answer the question. Scientists use radiometric dating to determine the exact age of rocks. What might scientists hypothesize about the natural structure shown in the image? (1 point) Responses The lightest layers on the structure will be the oldest, while the darkest layers will be the youngest. The lightest layers on the structure will be the oldest, while the darkest layers will be the youngest. The highest layer on the structure will be the oldest, while the lowest layer will be the youngest. The highest layer on the structure will be the oldest, while the lowest layer will be the youngest. The lowest layer on the structure will be the oldest, while the highest layer will be the youngest. The lowest layer on the structure will be the oldest, while the highest layer will be the youngest. The darkest layers on the structure will be the oldest, while the lightest layers will be the youngest.
The lowest layer on the structure will be the oldest, while the highest layer will be the youngest.
Why do convergent boundaries cause the formation of volcanoes? (1 point) Responses When two plates collide, one goes under the other. This creates an area of high pressure, which causes mantle rock to melt into magma and shoot out onto the crust. When two plates collide, one goes under the other. This creates an area of high pressure, which causes mantle rock to melt into magma and shoot out onto the crust. When two plates move away from each other, they create a crack in the crust, or a fault. This fault can go all the way to the mantle, causing magma to shoot out onto the crust. When two plates move away from each other, they create a crack in the crust, or a fault. This fault can go all the way to the mantle, causing magma to shoot out onto the crust. When two plates move away from each other, the crust gets thinner. This allows magma to shoot out onto the surface of the crust and harden. When two plates move away from each other, the crust gets thinner. This allows magma to shoot out onto the surface of the crust and harden. When two plates collide, part of one plate is broken. This creates an area where the mantle is exposed to the air and magma shoots out onto the crust.
When two plates collide, one goes under the other. This creates an area of high pressure, which causes mantle rock to melt into magma and shoot out onto the crust.
