Answer:
Option A. is correct
Explanation:
Given:
A sediment core is removed from the floor of an inland sea. The sea has been in existence, off and on, throughout the entire time that terrestrial life has existed. Researchers wish to locate and study the terrestrial organisms fossilized in this core. The core is illustrated as a vertical column, with the top of the column representing the most recent strata and the bottom representing the time when the land was first colonized by life.
Solution:
A sediment core refers to a mud collected by the scientists from the bottom of lakes to interpret past ecosystems.
To assign absolute dates to fossils in this sediment core, it would be most helpful if volcanic ash layers were regularly interspersed between the sedimentary strata.
The effect that the silk road had on trade was massive; The Silk road brought people far across Asia and Europe bringing different aspects of their culture with them.
I live close to the Everglades! It’s a national park where lots of exotic animals live. It’s 1.5 million acres of tropical wetland. In the 1800s they were gonna drain it but the idea went away. 50% of the original wetlands have been turned into farmland and urban areas
Answer:
1. Divergent.
2. Transform.
3. Transform.
4. Convergent.
5. Divergent.
6. Transform.
Explanation:
A landform refers to a geomorphic or natural feature of the Earth's surface, which typically makes its terrain. Some examples of landforms on planet earth are mountain, plains, valley, hills and plateau.
Basically, the tectonic plates such as the oceanic and continental lithosphere interact in three (3) ways and these are; divergent, transform and convergent boundaries.
Matching the various types of plate boundaries with their description, we have;
1. <u>Divergent</u>: plates are moving apart from one another. An example of a divergent is the Mid-Atlantic Ridge. Mid-ocean ridge is a seafloor or underwater mountain range formed where tectonic plates pull away from each other at a divergent plate boundary. It is approximately about 65,000 kilometers deep. Some examples are the East pacific ridge and Mid-Atlantic ridge.
2. <u>Transform</u>: plates are sliding past one another horizontally.
3. <u>Transform</u>: this boundary is normally devoid of volcanism.
4. <u>Convergent</u>: where lithosphere or crust is sinking into the mantle. An example of a convergent is where subduction zones or collisions occurred such as the west coast of South America.
5. <u>Divergent</u>: characterized by basaltic volcanism and seafloor spreading. A rift valley are formed at where Earth's tectonic plates rifts and it's a lowland region found both at the bottom of oceans as a result of seafloor spreading and on land. Some examples are the Rhine Rift valley and Baikal Rift valley.
6. <u>Transform</u>: it is a boundary that we assign to the San Andreas fault.
Answer: D. Sea level drops when water is stored in expanding ice sheets and continental glaciers.
Explanation:
One of the most important and influential factors in the change in sea level is <u>the change in the amount of ice that covers the Earth</u>. This is because much of the planet's fresh water is stored in glaciers and ice sheets.
Then, the more water exists in solid state in glaciers and ice sheets, the lower the sea level. However, today the opposite is happening, due to the accelerated climate change, which has caused the melting of glaciers and sea level rise.
