geo b mid-term exam answers for 9th grade
1. What are the three types of plate boundaries and give an example of each?
- Divergent boundary: Plates move away from each other, for example, the Mid Atlantic Ridge.
- Convergent boundary: Plates move towards each other, for example, the Himalayas.
- Transform boundary: Plates slide past each other, for example, the San Andreas Fault.
2. What is the difference between weathering and erosion?
- Weathering is the breaking down of rocks into smaller pieces by natural processes such as wind, water, and temperature changes. Erosion is the process of transporting these broken pieces of rock from one place to another through natural forces like wind, water, or ice.
3. What is the difference between latitude and longitude?
- Latitude is the distance measured in degrees north or south of the equator, while longitude is the distance measured in degrees east or west of the Prime Meridian.
4. Describe the difference between a hurricane and a tornado.
- Hurricanes are large, powerful storms that form over warm ocean waters and have a well-defined eye at the center. They typically last for several days and can affect a wide area. Tornadoes, on the other hand, are smaller, more localized storms that form from thunderstorms and have a rotating column of air. They are typically short-lived but can be very destructive in the area they impact.
5. What is the difference between climate and weather?
- Climate refers to the average weather patterns in a region over a long period of time, usually 30 years or more. Weather, on the other hand, refers to the day-to-day conditions of the atmosphere in a specific location. Climate is the long-term trend, while weather is the short-term variation.
