Answer:
The three primary methods are: Radiation Measurement. Stratigraphic Superposition. The Fossil Record.
Explanation:
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.The best estimate for Earth's age is based on radiometric dating of fragments from the Canyon Diablo iron meteorite. From the fragments, scientists calculated the relative abundances of elements that formed as radioactive uranium decayed over billions of years.
Which of the following is accurate about monsoons?
Check all that apply.
A. Heavy monsoons hurt the affected economies.
B. Indians prefer heavy monsoon seasons.
C. Monsoons create a perfect environment for rice farming.
D. Monsoons can cause devastating landslides and floods.
Answer:
D. Monsoons can cause devastating landslides and floods.
Explanation:
Monsoons require a large area of land and oceans, they occur where large bodies of water are limited to large land areas.
Monsoons are formed on the shores of certain oceans in both the southern and northern hemispheres. The most pronounced monsoons are formed over the Indian Ocean and the southern part of Asia. They come to it in the summer and start from the Himalayas during the winter.

Rainforests are a feature of
the Columbia Basin.
the Olympic Mountains.
O the Puget Lowlands.
O the Willapa Hills.
Answer:
Rainforests are a feature of the Olympic Mountains.
Explanation:
The rainforests are something that is associated with the tropical regions around the Equator. This should not come as a surprise as the vast majority of them are found in this part of the world, but very often it is forgotten that there are other rainforests, outside of the tropics. These rainforests have all very similar characteristics to the tropical rainforests but they are located in the temperate regions in the mid-latitudes.
One such rainforest is found near the northwestern coast of the United States, in the state of Washington, on the Olympic Mountains. These mountains are located just above the coastline, and because they act as a barrier, the constant humidity that comes from the ocean is built up and there is rainfall throughout all of the year. Because there is rain all year round, there is lush vegetation, though it has to be noticed that the amount of plant species is relatively low compared to the tropical rainforests. The animal species tend to be in a higher number than in most of the other biomes in the temperate climates but again much smaller than in the tropical rainforests.
