What was Charles Darwin job on the ship?

In 1831, Charles Darwin received an astounding invitation: to join the HMS Beagle as ship’s naturalist for a trip around the world. The life of Charles Darwin “Charles Darwin was born in England on February 12, 1809. His father wanted him to become a doctor, but the young man was more interested in nature. He

What is fast mass wasting?

Mass wasting is the movement of rock and soil down slope under the influence of gravity. Rock falls, slumps, and debris flows are all examples of mass wasting. Often lubricated by rainfall or agitated by seismic activity, these events may occur very rapidly and move as a flow. What is rapid mass wasting? In rapid

What are the types of divergent boundaries?

There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges. What type of boundary is divergent? A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface,

Which terrestrial planet has the youngest surface?

Why does Earth have the youngest surface of all the terrestrial planets today? the Appalachian Mountains. Why does Earth have the youngest surface of all the terrestrial planets today? It is the largest terrestrial planet so its interior has not cooled too much. It is not so close to the Sun that it has lost

What are three types of convergent boundaries examples?

There are three types of convergent plate boundaries: oceanic-oceanic boundaries, oceanic-continental boundaries, and continental-continental boundaries. Each one is unique because of the density of the plates involved. What are 3 examples of convergent boundaries? Three types of convergent boundaries are recognized: continent‐continent, ocean‐continent, and ocean‐ocean. Continent‐continent convergence results when two continents collide. … Ocean‐continent convergence

Where does compaction and cementation occur?

Rainforests, dry forests, sand dunes, mountain streams, lakes, rivers, oceans, beaches, and deltas are just a few examples of where compaction, and eventually cementation, can occur. What rock is cementation and compaction? sedimentary rock After compaction and cementation the sedimentary sequence has changed into a sedimentary rock. Sedimentary rocks like sandstone, shale and limestone differ

What are the 5 forces of mechanical weathering?

The 5 types of mechanical weathering include thermal expansion, frost weathering (or ice wedging), exfoliation, abrasion, and salt crystal growth. What are the 5 forces of weathering? Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the

How does the moment magnitude scale work?

The moment magnitude scale is based on the total moment release of the earthquake. Moment is a product of the distance a fault moved and the force required to move it. It is derived from modeling recordings of the earthquake at multiple stations. How does the moment magnitude scale work for kids? The moment magnitude

Where is a reverse fault?

Reverse faults are exactly the opposite of normal faults. If the hanging wall rises relative to the footwall, you have a reverse fault. Reverse faults occur in areas undergoing compression (squishing). Where is a reverse fault found? Reverse faults, also called thrust faults, slide one block of crust on top of another. These faults are

How many main layers does Earth have?

three main layersthree main layers. The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. Earth’s interior is generally divided into three major layers: the crust, the mantle, and the core. How many main layers does the earth
